This Gibson amp has 2 speakers, a 12 inch and an 8 inch.

Jim Hall's words: "I used a Gibson, I actually remember the number, it
was a GA50. I love the sound of tube amps in general. I don't know, I
may have been able to get used to a Fender but there was something
about the subtlety of that amp that I liked. I liked the way it
looked, like an old radio."

Jim used this amp for several years, but it eventually became too
fragile to take on the road. Since then he's been trying to get as
close to the sound of the GA50 as possible.

I heard him play through that amp at The Clifton Tap Room in NJ many years
ago. That thing had unbelievable sustain.

If I remember right, that is also the amp Howard Roberts played when he came
to Calif. I think his album, "Meet Mr. Roberts" was recorded with this amp.

The one he plays on that old film (Legends of Jazz Guitar video) looks like
a small sideboard!

I've often wondered why no one makes a clone of that amp, given its
place in the history of jazz guitar. I've seen the schematic and it's
not complicated at all. It was a cathode bias power section IIRC. Are
there other old Gibson amps that come close in tone? Also, I believe
Barney Kessel may have played one of the old Gibson amps in the late
'50's, though not sure which one.

What would be the advantage of the two speakers?

Blending of speaker tones I would imagine. Even today I occasionally
hear of guys trying 2 completely different speakers (simultaneously)in a
2-12 amp, just to see of they can get a unique sound from the blending
of tones that couldn't be achieved by using 2 identical speakers. For
example an EVM 12L and Celestion.

In this case one's an 8 and ones a 12 so the 8 probably helps out with
the highs.

The Gibson Ga 50 is one amp i would love to own. All of the jazz
greats played it at one time or another. Many say its the best
sounding jazz amp ever made. I played one 1x and it was very special.
If someone is selling an ALL original one, please feel free to email

Looks like it's been through a war (and lost), but....

Don't ship UPS or it will be in worse shape.
It is is great amp. It is the sound most players want; a great
midrange. Like I said I own one. I used to play it a lot. She like a
little old lady, very fragile. You are scared if you bump into her she
might die! That is why it is the closet today.

I was interested in this amp at one time. I played it at a local
shop. It is no GA-50 but a great amp just the same:
