I'll bet more than a few of you have been in this situation. I just put together a new amp: Aguilar DB 659 followed by a Stewart 1.6. To replace an old amp which just wasn't meeting my needs: Trace Elliot GP7SM 300W at 8 Ohm (Pre Gibson) Now, just two days later, I'm having second thoughts about selling off the Trace. This thing has been the most solid piece of gear I've ever owned, and has been a trusty partner for the last 8 years. I'm not sure I can part with it. It's still solid, in perfect condition, and sounds great. You see, I made the mistake of listening to some old recordings and got all sentimental. I've had this feeling about basses before (still have my Steinberger from '85 even though I HATE playing it now) but never expected to have the same feeling about an amp. I figger I can get $300-$350 for the Trace, but is that worth parting with it? I'm not sure.
