From private collection up for sale very rare, excellent condition 1975 Ampeg G115, 175W with Spring Reverb and Tremolo.
Fully working, complete with service manual and original two button foot-switch.
Serial no. A 168293, manufactured in the U.S.
I’m quite confident saying this is the best condition and the more complete G-115 on the market.
The amp has been fully serviced and checked by GB Electronics (all pots have been sprayed out, all hardware tightened, all voltages have been tested to ensure optimal functionality).
Photos speak for themselves.
