Ampeg "Diamond Blue" reissue series amplifiers
Mark Daigle
A question for any of you who have experience with the new "Diamond
Blue" series reissue amps from Ampeg. These include the Jet, SuperJet,
and ReverbRocket models.
Do you notice that the apparent volume (or sound pressure level), fully
cranked, is lower than it should be compared to similar sized amps?
I've seen other people's similar comments and wonder if it as an Ampeg
design problem or some of us just have lemons.
Feel free to share any other thought on these amps as you see fit.

Interesting to see another post on this issue...
I just had the local store put one of these on hold for me with the intent
to buy - my condition was that it be new in the box because the floor model
I tried couldn't seem to bother others in the store wide open at 10 in the
clean channel. I figured it was just the "floor model".
Now a red flag has definitly shot up and I'm going to rethink it. Too bad
because it had a helluva sound.

My first amp was an Ampeg Jet back in 1963. I never really liked it. The
chrome sheetmetal box used to get extremely hot! I got rid of it as soon as
I found something better. Good luck with the reissues.

I 've played through a late 60's or early 70's Reverb-o-Jet. It was brown
with a cool VU meter on the top. It got a great sound for such a small amp.
The reverb was maybe the best I ever heard. ( It did get hot.)
I still have a 60's G-12 combo that is big and heavy as hell, but " the
apparent volume (or sound pressure level), fully cranked, is lower than it
after beat switch on the tremelo.
I also played through what looked like the guitar version of the SVT. (
V-12? )
It was a screamer when cranked, and LOUD. No good for small clubs though.
I miss it.

the new Jet Reissues are great amps. I've got a J-12R and the amp is
loud enough to rehearse with a band (if the drummer is not Animal from
the Muppets Show:-)). I like the clipping of the poweramp (kind of Kiff
Riffhard Tone) if you turn the amp 3/4 up. The only downside is the
speaker...very weak. I made myself a speaker input and tried several
other speakers. The Celestion Vintage 30 does a very good job.

I've got a Jet reissue (purchased) and a Superjet reissue (gift).
First, the J-12R: I bought this amp for it's class A sound. I have used it with
a drummer. It rolls off into a great natural distortion at low volumes and
cranked it really screams. It is a little louder than my 12 watt Princeton at
cranked level. It sports 15 watts through an Ampeg 12" speaker.
I think class A amps may just have a lower volume level per watt than class
A/B.
It is great for certain types of music, but if you want clean headroom at loud
volumes forget it. It is a bit of a one trick pony in this regard. The reverb
is different than Fender's but still sounds great.
For reasonable level Rockabilly tones this amp excels.
The SJ-12R is a different animal. It is class A/B at 50 watts through an Ampeg
12" speaker. It has a large amount of headroom. I'm using it at a gig in a
couple of weeks because this headroom allows a lot of versitility in sound. I
A/B'd it with my 100 watt Fender Twin and it distorts at a higher sound level
than the Twin! So to play loud an extremely clean for jazzy songs I am going to
use the Super Jet.
The SJ has a three stage EQ and needs considerable tweaking to get "the tone."
With my Fenders it is difficult to get a bad souns no matter how they are set.
The Ampegs look about as cool as an amp can look. Blue pilot light and all. The
construction seems sound. But I haven't played out much to test their
ruggedness. They come with Five-year warranty. A minor irritation is having to
pull the back panel off to access a fuse. I haven't blown one yet. Luckily.
I'm happy with both of them. The price is right too.
See Harmony Central (www.harmony-central.com) for more (mostly negative)
reviews on these amps.

I'm not a techie, but Class A amps are less efficient than A/B amps
and so are probably not as loud. I have the Jet myself and think it's
a pretty good buy. Max volume probably occurs shortly after the 12
o'clock position. After that the saturation increases but the volume
doesn't change too much. For $250 bucks or so I think it's a good amp
for a single coil guitar. My Telecaster sounds best with the Jet, I
had an Epi LP at one time that sounded horrible through the Jet.
The reverb was one of the better reverbs in that price range also. My
local store has a Laney VC30 for $299 thats awfully tempting, as is
the $299 Spruce topped Seagull, and the $240 Boss ME-30 is pretty cool
too. Not to mention...man my G.A.S. is really acting up lately.

OK, I just took a peek inside a reissue ReverboSprocket
and made the following observations:
1.The plate voltage on the EL34's is low compared
to most other amps that use EL34's. I didn't get to
bench test it, but I'd guess it would put out only about
30 watts.
2. I guess for $250, it would be a good deal, but
if I were you, I'd keep it til the warranty expires
& peddle it. Inside it's built like a Crate, and has the
same pots & PC mount electrolytics that will
probably crap out after a couple years of regular use.
What's more, the PC board is only accessible
from one side, so if any parts have to be changed, you're
gonna pay to get the whole thing pulled out,
even if it's just one lousy resistor.
3.If you're expecting the same tone as an original
ReverboRocket..don't think so. For one thing, the
originals had 6V6's or 7591's, which don't sound like
EL34's. I asked one owner of an original RR
to try it, he described the reverb as "heinous"..
well, he is an Ampeg amp snob, so
of course an overly negative opinion might be
expected..but for $250 new, I don't think I'd
expect the same tone as an original.
4. IMHO, this amp would probably benefit from
using some good 6L6's or 6V6's, and some
different 12AX7's.

I own two Super Jets (SJ-12R) and I think they're fantastic. They are the only
amps I chose to replace my 1965 fenfer Deluxe Reverbs. However: I am trying
to get a little more low mids out of them..anybody out there try replacing the
stock 12" with a Celestion or similar?
GtarGeorge
I read your post about the SuperJet. I was thinking of taking out the 12" that
came with it. A guy at Ampeg suggested the Celestion G12-30 (Vintage style)..it
seems that's what you put in yours. Did you get a little more low mids by
doing this? Was the impedance a problem (isn't the stock 12" 8 ohms..isn't the
Celestion 16ohms?) And did the amp seem louder after the switch?
Please reply..No one around here knows dip about this. I'sd be happy to
correspond about any of my Ampeg experiences. Thanks in
advance...GtrGeorge@aol.com

I bought a used R212R a couple of weeks ago and like it a lot. I
tested it side by side with a gaggle of other 25 to 80 watt tube amps.
It wasn't as loud as most others, but not noticeably so. It was used,
eight months old. Soon, I am going to replace tubes and speakers.
I'll probably use Celestions Vintage 30's. PLEASE, if you have tried
different tube/speaker combinations in this amp, let me know your
opinions. I have heard that the Ampeg speakers are not the best, and
I'm wondering how much the tone and/or even the volume will improve
with Celestions. Thanks, all.

Did Ampeg ever get the cabinet buzz worked out on the Jet re-issues
(J12-T/R). Last time I played one (about a year ago) they buzzed like a
bumble bee at certain notes and volume levels. I could just about get one
to do the "Satisfaction" tone on demand.

I recently purchased an eight month old R212R Reverberocket. I've had
no problem with buzzing or rattling, even when cranked.

So, how do you like it? And what guitar are you playing through it?

You're lucky! Most everything I've ever played from the St. Louis Music
Co. buzzes like attack of the killer bees. Not to belittle the tone of
some of these amps--I dig my Crate VC3112.
Perhaps someone can help me here: I know Crate makes a head version of the
50 Watt VC. Do you suppose I could purchase an empty head enclosure and
drop my VC3112 chassis into it? Crate doesn't have an e mail address
posted on their site.
