Like some others, I'd never say "never", but I'm very attached to my '91 Thumb. Although I would consider selling it if I found a '91 or earlier Thumb 5...
I think I'd wanted one since 1991, so it's quite fitting that I got one from that year. And it was mostly from listening to Fishbone, and then seeing how gorgeous they looked in the flesh in Carslbro Sound in Leeds when I was 16.
This one is as good a Thumb as I've ever played, it's got the sound, the looks, the lot. Every time I pick it up I smile.
