This has happened many times. While listening today to some old projects that were finished or stalled for some reason, I heard a GREAT clean sound I got with a Tele plugged into the clean channel of a HotCat 30, SM57 into a GR NV-1 preamp. I love this sound, yet the Cat and the preamp are gone. Sold them. I can't count the times this has happened: I hear a track I really like and I've sold the gear! Maybe it comes down to the fact that there are so many great amps and we can't keep them all. I hope it's not some self-destructive psychological disorder at work.
