I was speaking with a high end, custom pickup designer/maker the other day, (no, not someone at Bartolini, Basslines, EMG, DiMarzio). Two observations he had about bassists - 1. He said that in his experience, bassists are far more concerned with tone than guitarists. He finds we are much more concerned with lows, mids, highs, transparency, tone colors, et al, whereas guitarists tend to be concerned with sheer output as much or more than how something sounds. 2. Based on the orders he gets, and the feedback he has heard from the 200 (approx.) custom luthiers he deals with, he said over 90% of bassists want something innovative, unique or different when it comes to custom gear, whereas, about 5% of guitarists want something that is not already an existing, standard, design or sound, or based on one. This parallels what Ned Steinberger said - "They're (bassists) not so satisfied with their instruments, they're not so well established...I think guitar players like to have a lot of different guitars and don't necessarily want to spend all that much money on them whereas a bass player's more likely to have just one or two instruments," (some of us nonwithstanding), "and put everything he's got into those."
