Oddly, I've made it this far without ever really playing a jazz bass. By playing, I don't mean actually owning. I have hardly ever spent time playing a jazz bass, except for about 10 total minutes in stores over the years. Always liked the sound, but never really wanted to buy one. I'm starting to heavily consider a purchase, so I demoed several today and came away with this... The pickup volume controls seem almost binary to me. When I try to blend the two pickups to achieve different combinations, the tone changes immediately when I take one off of full volume, and any lowering of the pickup volume after that is hardly audible. It sounded to me like I was hitting an on/off switch rather than making gradual adjustments, and really limited the range of tones I was able to achieve. Jazz basses are new to me, but seem very simple so I was a bit perplexed by the lack of flexibility. Can any of you jazz players (or detractors) elaborate on this a bit? Are there some simple mods that can achieve more of a useful range out of the pickups? FWIW, I tried several models of passive jazz basses, so my assumption is this is pretty much just a characteristic of jazz basses.
