This seller in Northridge CA (Los Angeles area) is offering a cosmetically challenged Ampeg Reverbrocket 2 (GS-12G). These are from the late 1960's and they are one of the more desirable of the Ampeg Combos. This one is a little worse for wear - seller says its been in storage for 35 years - but they say it was brought up slowly on a Variac and is in good working condition.
Definitely worth a look if you are in the market for a vintage tube combo and don't have a lot to spend. These old Ampegs are built very solidly. The reverb circuit is different than the Fender circuit and I think the Echo is more like "oil can" echo. You will see RR2's out there in much better cosmetic shape but those prices are generally several hundred dollars more than this one. - Jim C.
