I bought this off a fellow TB’er thinking I would keep it, because it’s just an awesome sounding amp. Perfect for studio use or light gigging. The only reason I’m selling is that I typically play a Warwick Thumb, and it likes my GK combo better for the small stuff. With a passive bass, this amp slays all of the competition. active basses sound great, but past 50% gain it gets pretty dirty (a good dirt, but I like my Thumb clean). this amp is in mint condition. The only non-factory thing is the v2 (preamp/eq) tube has been replaced with a JJ 12ax7. Stock tube is a ruby 12ax7. If you use a at7 tube, you will get a cleaner tone, but a little less volume. My Warwick liked the at7 better, but I’m selling the amp with the 12ax7 since that is how it came from the Factory. $700 shipped in the original Ampeg Packaging.
