I played a used Seymour Duncan amp (not the convertible) but I think
it was called the 84-40 or something like that. Anyhow I was at a
conference for work in California. They wanted something like $200
for this amp. It sounded absolutely great for blues - I don't think I
have every heard a better sounding blues amp played direct w/o effects
- seriously! This is from a person that owns a Black Face 66 Fender
Super Reverb. If you pushed the distortion, it got muddy and did not
sound the best. I should have bought it and had them ship it to me.
It is gone. I didn't much money at the time and was concerned about
shipping it. I could kick myself.

Is this a very common amp? I have only seen one, but I have seen
several convertibles in my time. They have a bad reputation as being
unreliable. Does anyone know when this was made? and how much is one
worth?

I've never heard of an 84-40. As for the convertables, I've heard the
same thing about reliability. However, I've known a couple guys that
have owned then (played in a band with one of them) and I absolutely
cannot speak highly enough of the tone. In fact, I would have bought
one myself, but I didn't want to sound like the other guy ;)

Hi, I've seen a few 84-40's either advertised fs or in stores in New
England..I think they're early 90's , and I've seen them used between
250-350..I don't think they were much more than 350.00 new...I've owned a
Convertible for over a year now, and played it out much as well as home,
and it's been very dependable, and sounds Great...It seems a bit fragile,
and heavy as hell, but I'm pretty careful with it in transit...Nice amp,
imo..ERIC

I owned one for a while. They were very common about 5-6 years ago, at
least out here in L.A. I really liked mine for awhile, but grew tired of
it. It's *supposed* to be like a cross between a Deluxe and an AC-30. More
like a British Deluxe to my ears. The clean was nice and if you really
mess with it, you could get some great bluesy distortions. But the tone
controls are the same for both channels, and what works for one channel
doesn't work for the other, at least not for me.

I payed somewhere around $600 for mine. Sold it last year for $250. If you
like it, $200 may be O.K. A word of caution. They are very un-road worthy!
They're wired in Korea or somewhere like that. I actually had an amp
technician tell me (after about my third time bringing it it for loose
this and that) not to bring it in to him again. He wouldn't work on it,
said it was built too flimsey. Of course, I was tossing it into my car for
club gigs, casuals, etc. If you use it at home your mileage might be a lot
better!

Now I throw a Peavey Delta Blues (with a 15") in the car. Built and sounds
much better! For the studio I use my '60 Ampeg Jet and my '63 4x10"
Concert, a Boogie preamp and/or this new Boss GT-5. The vintage amps
*don't* get thrown in the car!

Good Luck

Lord Valve Speaketh:

There were several incarnations of this particular chassis; some were
made in the US and some were from Korea, I think. 4-EL84s in the
output circuit. Very cheesy construction; lots of vibration-related
failures. The pots have very thin shafts, and break off all the time.
The jacks break often, too. Has a dirty channel and a clean channel,
with switching. Hard to work on. Sounds pretty good when working
right, which ain't all that often. I think there was a 2-10" and a
single 12" type, and I seem to recall that there was an 84-50, also. I
only see one or two per year for servicing, so there aren't a lot of
them around (at least, not in Denver).

Had one . Got it for 150.00 used. Sell out Chinese amp. Very cheap. Plastic everything. Tube sockets horrible. Glassy brite tone. Can be loud. Drives a 4x12 boogie cab. But worth 150.00 no more.

Probably worth what they were asking, maybe including shipping.
However, the build quality would be mediocre at best. PC board
mounted pots and caps, not good old easily repaired PTP.
Check the innards out on youtube:

I wouldn't go to the trouble to hunt one. I know some of those
kind of amps can sound pretty good. But I'd stick with the
Super Reverb. If it doesn't sound better that the object of
your desire, maybe it needs a tune-up.

Hey, Rocket Scientist? Do you realize you just replied to a post
that is *TWENTY* *THREE* *YEARS* *OLD*?!?!?! Fucking genius
you must be. I'm sure John Thornburg will be thrilled that he
finally got an answer, eh?
