I myself own a lovely 4003 midnight-blue Ric, and am VERY happy with it! Now here's something I've always wondered... I've always heard about how the 4001's have the old trussrods, and how they were designed for relatively low tension strings (Ive read in alot of cases people routinely have problems with these basses when they are strung with regular roundwound strings). Anyway, this goes to say not ALL 4001's are susceptible to the dreaded "bent rods syndome", but I've always wondered about the Rickenbacker 4000's (the ones with one birdge pickup, and a tone and volume knob)... to anyone who has ever played one, owns one, or knows about it: how are the trussrods and necks for these babies? in comparison to the 4001's? just curiosity!
