I saw your post from ages ago. I have a Kolbe GP-1. I'm sure it is about 20 years old.I have used it very sparingly, as I had wanted a good direct pre-amp for studio use. I took it on one live gig. It is in pristine shape. I actually had Harry do some work on a DeLuxe Reverb of mine and took it to him to simply look and an checkout at the same time. His comment was, "Yeah, this is one of my better ones." If you are still interested, though I know it's been a while since you were looking, reply to this.
