I've got an older KMD 1x12 solid state amp. All made in the UK, even the small electronic bits inside. I really like the clean sound, and the amp gets good and loud. I'm completely customizing the it right now, and I've been taking pictures as I progress.
Main tasks:
Fix gain channel's post knob (completely non-functional)
Replace speaker (ripped cone on celestion, replacing with carvin

Completely reupholster the cabinet
I've already made some good progress, and I'm having a lot of fun. Can't wait to do it on a better amp someday. I'll post pictures when I'm all done.
