I saw this second hand 4-string bass at local music shop and bought it. The price was about $300. The thing that confuses me most is that it looks exactly like Warwick Thumb (the headstock too). It has passive electronics, on the pickups it reads gotoh and there's a high-gloss lacquer finish on it. The bolt-on 26-fret neck is attached differently to the body than in the original Thumb. I have no idea who made this bass. There is an odd-looking logo on the headstock resembling the letter T, but that hasn't helped me much. Does anyone have any idea what this thing could be?
