Super 60′s sounding. A tech recently went through it, and replaced all the caps. It’s all original, along with the original 1961 Jensen speaker in it. Some of the tubes may not be original though, due to age. It also has the original built in foot switch. The power cable looks to be original. The tremolo is working well. The only issue that I know of, is that you go to use the foot switch to turn the tremolo off, the tremolo doesn’t go all the way off, it just lowers the tremolo effect. So you have to turn the depth knob all the way off if you don’t want the tremolo effect. Showing it’s age. Control panel has rust, wear on corners, and a few cigarette burns. But hey, that’s rock’n’roll! It’s working great. The item “Gibson GA-8T Discoverer Tremolo 1961 Vintage Tube Amp Guitar Amplifier withJensen” is in sale since Thursday, November 7, 2019.

Cool old Gibson Discoverer Tremolo GA-8T amplifier. I had my amp tech go through and replace the caps. Otherwise all all original – has the original 1961 Jensen speaker in it. Also some of the tubes may not be original as this is an older amp. Has the original built in footswitch. Power cable appears to be the original one. Working well, Great sounding amp. Tremolo working well, footswitch working – the only issue noticed is that when you use the footswtich to. Turn off the tremolo it does not go all the way off, it just lowers the tremolo effect. So you have to turn the. “Depth” knob all the way off if you want no tremolo effect. Nice old amp, Don’t Miss out! Please see all pictures Blond original covering shows age but still good. The control panal is pretty rusty with age. Wear on corners, a few cigarette burns.

This has been gone over by a tech with the capacitors and resistors replaced and any weak tubes. Speaker is original with numbers of 220034 10J11 V1373. It is working and loud on input #2. It has no hum at all until you plug a guitar cable into it and then it has a low hum/buzz on input #2. Hum does get louder as the volume is turned up but I can’t hear it when the guitar is playing. You can see the parts that were replaced in the bags I show and the old parts are included. Also a new feed power wire has been put on both the amp and pedal. The 1/8 rca plug on the pedal plugs in very tight. Cosmetically some of the covering needs glued back down and there are some stains and missing covering. Gibson logo on the grill side is partially missing and there is some wear to the cloth grill. Last to note is that the cover for the tubed section is not original and you need to drill the 4 holes to mount it yourself. It is the correct size and fit and a tweed material but does not quite match the rest of the amp. Base is 20″ wide x 8 3/4″ deep. Height is 17 1/4 with the carrying handle folded down. Age is late 1950′s to early 1960′s. Lettering on the metal plate is pretty good. I’m not sure if the nobs are original or not–they could be replacements but certainly close to original if they are. I will be listing several of these with this one being the best looking. I’m rather disappointed that input 1 did not work as when I bought it I was told it was fully working—and it is other than that input. Tubes are 12AX7, pair telefunken ECL82, 5Y3GT. I believe the speaker code dates this one to 1960. The items I sell Might or Might not be from a smoke free home. Most items are used and vintage and smoking occurred in almost 50% of the homes in the US at one time.

This has been gone over by a tech with the capacitors and resistors replaced and any bad tubes. Speaker is original with numbers of 220034 10J11 V1373. It is working and loud on both inputs. Hum does get louder as the volume is turned up but I can’t hear it when the guitar is playing. You can see the parts that were replaced in the bags I show and the old parts are included. Also a new feed power wire has been put on the amp. I have no tremolo pedal for this one but tested it with the pedal from my other one and tremolo works good. Cosmetically this is the ugliest one I have but case is sound. Some of the covering needs glued back down and there are some stains/soiling and missing covering as well as a hole in the top of the cabinet. Gibson logo on the grill side is missing and there is some wear to the cloth grill.
