Are you sure that's vinyl? It looks more like double-knit polyester left over from a leisure suit.
So I just won this red vinyl Klira Triumphator - my offer for EUR 340 was accepted:
Sorry to hear it.I noticed the warranty disclaimers in the seller's listing, but it is described as Used, which includes "but is fully operational and functions as intended" in the definition.
He refuses to take it back. I'll try to deal with the back-bow by heat treatment.
Patient heat treatment can do a lot. I hope it works!
I remember some stories from friends here in the eighties in The Netherlands. One guy sold his '60s Höfner bass to buy an active 5 string. I guess we all thought carbon fibre and headless was the future. I guess it wasn't only Höfner but also certain guitars getting just not fiting ij with the neon coloured eighties.I read an interview once with a guy with a big Rickenbacker bass collection in the UK. In the eighties he spend all his student grants on Rickenbacker basses. People almost gave them away and bought modern stuff.
