Chapter 1:
In early Dec '05 a Guitar Center circular showed the new Vox AC30's CC
priced for less than $1000.00. Hard to pass up if the thing was even
remotely similar to the original, IMHO. I figured since I was in the
market for a new amp anyways I'd check it out.
Just to see what current owners were saying I went to Harmony Central
(www.harmony-central.com). Overall most owners were happy but a few
spoke of horrible problems within minutes. I wasn't really surprised to
hear that. Generally on Chineese imports like that you need to test 1
in 10 to get one that actually works right.
One of my first stops was at the Guitar Center store in Sherman Oaks to
speak of my concerns with a few sales folk there. After warming up the
amp I ran my typical chromatic scale exercises...whole notes starting
at the mid neck. Within SECONDS I noticed a strange oscillation
underneath my notes....as if the guitar was being piped through a
Eventide H3000 with the preset at -5 semitones. It wasn't loud, per se,
but loud enough for me to hear it. Thinking the amp was a bad model I
tested the next one. Same thing. I brought in the rep and showed him
the issue. To which he responded, "Hmmm...you're right it DOESN'T sound
right...it must be broken. Well...sorry that's all the stock we got..."
Chapter 2
The next day I went to Guitar Center in Lawndale Ca. Same thing... This
time I hunted down the kid that attacked me when I first walked in the
door and said, "Get your manager, you need to see this." At once they
arrive and I plug in to show my test. At first, because the ambient
noise level in the store was so stinking loud they missed it. "Get
close," I said, "and this time LISTEN!"
SILENCE....
"Wow," says the manager, "you know what you need?"
"No...what," I asked.
"You need to check out this original Vox over here...it doesn't make
that sound."
(Incidentally it also doesnt cost 1 grand either).
"NO," I said, "I came here for this model and I want one that works.
Either get me one that works or pull this defective stuff off your
floor so someone else doesn't get tripped up on it."
"Well, maybe something is broken...let me call the rep on Monday and
see what they say. I'll have little Joe here take care of ya."
I left them my info and said, "Make sure you follow up with me." And we
left it at that.
Chapter 3:
Since I was mildly entertained by the whole quandry I was bold enough
to try a fourth store. This time West LA Music would be my target.
After a quick walk into the amp room, (subsequently chasing out two
street kids making horrible noise), I was greeted by a sales guy to
whom I stated, "I'd like to show you something. Please come with
me...."
We promptly plugged into the AC30 1x12 (the 2x12 was not available).
"Does this sound right to you?", I asked as I tried my revealing tones.
The sales guy was stunned, as if he had just been hit upside the head
by the amp itself. "I have never heard an amp do that in all my life,"
he said, "something's not right."
"Well," I interjected, "if you can find me one that doesn't do that
I'll buy it." After respectfully taking down my info he said he would
contact the rep on Monday and get back to me.
Later that night I wrote an email to KORG indicting their product
deficiency to which I got no reply, short of a auto vacation notice.
Chapter 4:
Two days later both stores called me back and gave me Korg's direct
number. They both said it was out of their hands at this point. I
called the Korg rep they referred me to who, not surprisingly, had no
idea what I was talking about. I even had to start explaining why I was
qualified to comment on the issue. "Listen," I said, "Please just go
try my test and let me know what you find. I guarantee you will be
calling me back saying you can hear it. I am that confident of what I
am hearing." He agreed he would run the test and call me back.
About 30 minutes later I got a call from the Korg rep, "Dusk, we tried
it and you're right. We aren't sure what's causing that noise but we
think it goes deeper than just swapping out the tubes.... This could be
a more serious issue, possibly down to the PCB.... Anyways I asked
around here and Korg's position on this "sound" is that this is a
"characteristic" of the amp and we have no plans to modify the sound
out of it. Essentially, it's the nature of the beast..."
Funny, the last time I heard that moniker used was in analog tape
recording in reference to overbiasing, wow and flutter, and dropouts. I
never thought that a built in Harmonizer effect in a tube amp would
pass as a "nature" issue.
"You have got to be kidding," I stated, "selling this product knowing
what you now know borders on corporate negligence, and at the very
least there are ethical implications for walking away from a problem
like this. At one point you are going to have to deal with it. What
about product liability and legal stuff like that? What if all 3000+
amp owners out there file a class action suit? That's a big deal, isn't
it?"
"Sorry, have you tried looking at the older models from the 90's?" was
his response.
"Yes," I replied, "but there aren't any left."
"Well there is nothing more I can do for you, Dusk, try writing a
complaint or something." We hung up and left it at that.
Three days later I took his advice and wrote a letter to Korg demanding
that in the future they disclose this issue in writing to potential
buyers everywhere. I still have not heard back from them as of this
writing.
Since then two other stores were made aware of the issue and one claims
they will be doing something about it. We shall see...
Epilogue:
As one would expect, in my line of work we require intense attention to
detail. Especially a guitar that will be compressed at every stage of
recording. Eventually all sonic nuances reveal themselves, including
"unintended parallel 5th harmonies". As unfortunate as it is,
regardless of how many redeeming qualities there are in the new Vox
AC30CC, the product will not pass muster for my session work so I go
without. Equally unfortunate is the fact that several stores were made
aware of the problem but not one has actually pulled the product, or
even demanded an explanation for that matter, even though they all
admitted the problem sounded "bad". How is that for corporate
integrity?
Finally, it is my desire that current Custom Classic owners demand in
one voice that Vox develop a workaround for this issue. I believe Vox
has a responsibilty to solve the issue rather than ignore it. Corporate
responsibilty has become the platform for many political battles in
this day and age. IMHO this battle needs to be fought to prevent the
whoring out of flawed gear under the names of their classic originals.
Clearly, if previous revisions do not exhibit this problem then it is
not out of the question to modify the problem out of the new line. All
it takes is enough care to demand the level of workmanship expressed on
the models these manufacturers are attempting to recreate.

This is already out of control in the microphone world, as it is. And
lots of people just think tube preamps just sound gritty and distorted,
since they've never heard the real thing.
I think it's too late to fight this battle, but I wish you the best of

I don't think they are really attempting to recreate anything other than
the look and the nameplate, because sadly that's what sells product. To
actually make the electronics identical would cost a lot more money than
they're willing to pay.

Well.. you're determined.. I would have passed on the entire idea after the
third amp. What you are hearing may be some modulation from a cheezy design
, defective tubes... who knows. Probably not the guys who knocked the design
off.. Go for the orignal.
Well, as evolution tends to go about its business, Digitech one day
discontinued most of the classic rp units, keeping only the new,
cheaper, worst ones. And to the disapointment of maybe 2-3 hundred
customers, they pulled the plug on all of their lists without any
explanation.

Therein lies the problem - there were only 200-300 customers, and they
were customers of a discontinued product. The company isn't making any
money from you and they have to concentrate on the 20,000 people who
will buy the Jimi Hendrix pedal so they can sound just like Jimi.
Everything has become cheaper (you probably paid a small fortune for
your Digitech processor) and one of the ways that a manufacturer can
cut costs drastically is to cut back on support. Not just on-line
support, but phone support, and most important, sustaining support for
second-hand users. It's just not profitable, and once a company reaches
a certain size (or gets bought out enough times like Digitech) they
have to show a profit. The customers won't pay more money for the
products, so they have to cut somewhere, and there's only so many parts
you can leave out.
When TASCAM started their forum in 1998 or so the manager wanted all of
the product specialists to participate. Then they changed management,
changed direction, and you rarely heard from any of the TASCAM folks.
Then it was taken down. Mackie has a similar forum but their policy has
always been on of only monitoring and not participating other than to
correct a posting that's a gross error.
Strange about the Vox amplifier. I suppose that what will happen is
that those currently in stock will be sold out and it will be replaced
by another model. Manufacturers of this sort of gear don't do recalls
unless it's for safety reasons. And one reason why there's so little
money left over for technological innovation and support is because of
all the money they have to put toward product safety so they don't have
to recall or get sued for something that can actually win a court case.
Dusk did the right thing - he tried the amplifier in a store, heard
something he knew he didn't like, and didn't buy it. If more people
would do that rather than waiting until after they plunked down their
money, found that there was something weird about what they bought, and
post an "is this normal?" message on a forum, manufacturers would get
the idea that they're doing something wrong. But as long as people keep
buying, they'll keep selling.

I'll almost put money on the first, though.
When those cheap Zoom pedals came flooding in, I was amazed at how many
people were just throwing their money away without even getting it out
of the box. IMO, manufacturers like Digitech at that point decided to
focus more on the amateur segment than on the pro, hence the decay in
their product quality, generally speaking.
I never heard of a class action against any audio manufacturer, could
anyone enlighten me on this?
Everybody is moving production to China. But the thing is, if you go
to mass production abroad, you have to sell a _lot_ of units to make it
profitable. Your fixed costs are very high, even though the per-unit
cost is very low.
So, as a result, a lot of companies have moved into the amateur segment,
because that's where they can make the money. Margins are much higher
on that stuff than on high grade gear, the customers don't expect as
much support, and you can sell a lot of the stuff. It's a huge win for
the stockholders.

People said they wanted to file a class action suit against Mackie for
things like bad ribbon cable connectors in their mixers, and features
that appeared in ad copy that were never implemented in the products.
It's easy to say on a forum " users should file a suit" but it's more
difficult to actually do. I've never heard on one that got beyond the
net threat stage.
The usual way it goes is:
Lawyer: "Well, did you return it and get your money back?"
Disbruntled customer: "Yes, of course. You think I'm going to keep this
piece of crap?"
Lawyer: "So what's your point?"
at which point "False advertising" usually comes up, the lawyer asks
how you were harmed by the false advertising. When you can't come up
with any better reason than that you didn't have a cool toy to play
with at a ridiculously low price (as advertised, of course), the lawyer
loses interest,
Aphex did successfully win an intellectual property lawsuit against
Behringer (Mackie tried the same thing but flubbed it) but they
actually had a case and could prove a loss of market share.
They'll be concentrating on the 20,000 people who don't realize that
buying the Hendrix pedal isn't going to make them sound like Hendrix.

That's an easy question for Tech Support to answer.
Because of another fact that consumer OEMs are keenly aware of - a fairly
large percentage of people will never return a product or use the warranty
to get it fixed. Normally in manufacturing you want to fix problems as close
to the source as possible because the total cost of the fix increases as the
product gets further through the development process, with the most
expensive fix being after reaches the hands of the consumer. This
relationship works the other way if the majority of consumers don't take
action on their defective product, the manufacturer is free to focus on just
getting the product off the showroom floor, and simply eat the cost of the
returns they'll have to deal with.
Traditionally a company that did this would get a bad reputation and lose
business in the long run, but that factor can also be mitigated. They simply
buy somebody else's reliable name and run it into the ground, and keep
acquiring and milking quality companies as they need to. Quality costs, and
the companies that reduce their quality to the minimum to do business have a
big competitive advantage over companies that want to earn a long term
reputation as a quality manufacturer.
As you and other have said, the only counter-measure is us - our collective
ability to simply stop buying crap and insist on better products.
Unfortunately for many cash-starved musicians the mentality is like
gambling; "I don't care if 1 out of 5 fails out of the box, as long as I'm
not that one. I'm always going to buy the cheapest thing available.".

Then buy a Vox AC30, not some Chinese knockoff made by Korg.
I was hoping that the Chinese would turn out to be a good amp, because
it gives more preamp options. But, as I feared...
Which is exactly what happened to Vox the first time around. Thomas
Organ took it over, started making shitty amps, people stopped buying
them, & Vox dissolved. The current owners (Korg) are connected with the
original Vox in no way other than having purchased the right to use the
name & logo. Anybody can clone the original AC30 design, many have
improved upon it, but only Korg can call it a Vox AC30, & only Korg can
again ruin the reputation of the name.

Jim,
FWIW I've not heard the problem the original poster mentioned on my 2x12
with the blues. I can get it to produce ghost notes when driven hard
(dimed) with the filtering switch set to the smaller (20uF) "vintage"
setting, because of insufficient power filtration, but the ghost note
goes away when you switch to the "modern" (40uF) setting.
That's the only sound deficiency I've noted in what, three months now.
I'm not saying the OP didn't hear what he said he did, or couldn't make
my amp do it too <G>, just that I've not heard anything like it myself.
Walt Campbell

FWIW I mentioned little about any given style of music revealing the
undertones, it has more to do with plucking high frequency notes with
gusto and letting them decay on their own. 90% of the guitar work I do
involves heavy layering, in which 1/2 note and 1/4 note arpeggios ring
out (my reason for testing amps with chromatic scales to see how the
amp responds to simple waveforms).
These overtones would definitely show up in these instances. As I
mentioned to the GC rep. really sit down and give it another try. You
will hear it. I even called a few stores and had them try it without me
in the room and they confirmed my findings, also consider the amp Korg
tested as well.
As I said for $1000 if I found one that actually worked I'd probably
buy it...I accept the fact that I'd end up gutting most of it and
making it more like the original, if possible.
BTW the "second" amp I mentioned at the Sherman Oaks store was the one
with the AlNico's. There was no difference in the oscillation, short of
the fact that the oscillation just sounded marginally "better".
FWIW I would not pay the extra $600 for the factory installed AlNico's.
They were not $600 better.
Also as an aside (and I think I pointed this out in my post) this may
not sound exactly like a vintage AC30 but it DID sound good. Good
enough that I wanted to buy it. Unfortunately I can't deal with
uncontrolable oscillations in my music.
Happy New Year to all!

It's _possible_ that putting a better driver into the thing will fix
the problem. It's also possible that you'll find something else
wrong afterward.
Does the amp have a jack for an external speaker? If so, out of
curiosity, it might be useful to try it with one. The sound you're
describing sounds like it could be mechanical rather than electrical.
I'd suspect your guitar, but since others have confirmed the problem
with other guitars and other fingers, that theory's out. But it could
be a loose winding on the speaker voice coil - maybe they got a bad lot
of speakers.
Or if you can't plug in an outboard speaker, maybe you could connect a
recorder to the speaker using a cable with clip leads, and record a
bit. That would tell you if it was electronic, and would also give you
something you could post so we could hear what you're hearing. If the
recording is clean, that points back to a mechanical problem.
If it's a mechanical problem as I suspect it might be, as they probably
don't listen to every amplifier, they wouldn't detect it.

To the original poster -- If you want a real Vox AC-30, why do you want
the CC version of it anyway? Get one of the earlier Korg AC-30s that
are an exact copy of the old ones, rather than the CC model which is
the hot roded version. The earlier Korgs have a good rep. Or buy a
real hand-made PTP wired copy, there are many of them out there. You
can find them second hand for not much more money than a new CC with
good speakers.

Outstanding. I got it all on DAT, sending Buddy a CD copy on Tuesday. It
was a lot of fun watching those guys just jam for 3 hours. While I was
rigging the stage they were learning the material for the night. It was one
of those great gigs where everyone has fun. He played his old Dr Z Studio
(early Maz 38) 1x12 combo with an Airbrake early in the gig and then
straight open as it got louder. The fiddle player was no slouch, either.
Usually those guys with Grammy's on their mantle can play though.
He'll have to be saving for awhile..!
I'm sure it's there Dusk, I just suspect that I'm not good enough or
fast enough to "find" it <BG>!
Walt
I am not married to any particular model but the CC is readilly
available, and for tax reasons (12/31) that made it attractive. I still
have not found an older one though there IS one at the Sam Ash store in
Hollywood for $3000. They are selling it as "vintage" and apparently
the jerk for a sales guy I dealt with there said they move like
hotcakes at that price.
I told him he was nuts.

I didn't mean to suggest that you use it with an external speaker as a
work-around. I just thought it might give a clue as to where the
problem is, for those of us who you got curious.

Things are a little different in the UK - if they're making claims that
can't be substantiated in an advert then you can complain to the
Advertising Standards Authority who can force the advert to be withdrawn.
