hey guys, i'm looking at purchasing a used yamaha TRB4. it's one of the older ones, bolt on neck and a J/J pickup setup and 3 band EQ. Yamaha does my head in with all their model names and changes, but from what i can figure, the TRB4's now have a twin humbucker setup. it's selling for $599. from what i've read these originally listed as $1500. true? reckon that's a good deal? from what i can figure it's the same as the one James showed in this thread http://www.talkbass.com/forum/showthread.php?t=177091&highlight=yamaha+trb4 originally i was after a BB1500a, but they seem to be a bit of a rare commodity now days. I figured the JJ pup config on the TRB4 may be kinda similar. also, from what i can understand, the TRB's are a higher range instrument. just wondering if anybody has had any experience with this bass, and your opinions on the versatility of sound, neck, playability etc. that'd be greatly appreciated. cheers, Andy O'Neil.
