The J has only three main tones: neck pup full and bridge pup off, neck pup off and bridge pup full, and both pups full. All the other micro variations can be heard only by the player. So, VVT or VBT doesn’t matter.
I played a '69 Tele bass for years, and when I switched to a Jazz bass I thought this way... 3 basic tones, and messing with the pickups doesn't really do anything.
A huge light went off for me when I changed my
amplification. The amp and speakers make a massive difference. All the sudden I could hear all the details in the midrange. Even now, I have two different amps. One of them masks some of those subtle tone changes. With the other amp everything is loud and clear. With the good amp, the changes are even more pronounced when using a good dirt pedal or certain effects.
To me, it's like having a powerful midrange EQ control at your fingertips. Think about an engineer adjust the midrange knob on a console one or two clicks up or down. It's like that.
I have never use the bridge solo, but my basic tones are
(With each of these, I might also roll the tone off.)
- N/B full on
- N full / B off
- N full / B 25%-ish down (almost always with the tone down about 25%)
- N down 25%-ish / B full
I will use each of those during a gig depending on the song. Then I'm also adjusting my right hand attack in a number of different ways to make tone.
If you add B only on that mix, that if 5 very distinct sounds.
As far as the VVT / VBT debate -- I have two jazz basses, both with VVT. I have thought about making the second VBT or VT/VT - I'm more inclined to the VT/VT because it's just more different, and very in style right now.
