Jazz Bass series with no-load VVT

Ask and ye shall receive...



thanks Andy! I can tell what you mean about it getting fuller as both volumes open. I was not expecting the tone knob to have as much influence as it sounds in the vid, don't know why I thought that way lol

The change as you roll one pickup up or down is much more noticeable in person playing than the iPad mic was able to pick up. The video really doesn't do justice to the range of tone available.

If you lived closer I'd have you come over and demo the thing and make a proper video

I was just just looking for "variations on VVT" and ended up here! It sounds like I can try this mod with the new pots I acquired and add the grounds later if I want.

Going to be using a Kellingsound tone pot so I'll have to see how that plays into this before I commit... it arrives Friday

Furthermore, the diagram on the OP is for having the trace cuts, I can't seem to find a thread about the wiring w/o the trace cuts, can anybody point me in the right direction, or perhaps explain how to use the OP diagram to just do it the way he did? I was sure I could just dig it up from the forums but no luck...

Do I just focus on the wiring presented? Looks like he used red for hot...

You follow the wiring in the diagram in the OP whether or not you cut the traces. Cutting the traces only makes a difference when you have one or both pots full on (slightly hotter signal as though the pots were completely removed from the circuit when fully on) I never did cut my traces and it sounds great so really no need to cut them unless you want to squeeze every last little bit of signal out of your pickups.

If you need a diagram for wiring without cutting the traces just print out the diagram in the OP and take a pen and fill in the gap (on the diagram) where the trace is cut

Red in the diagram is just to keep it straight which pole from one pickup connects to which pole of the other pickup - don't assume that the color of your wire will be red

I won't assume, These are 3 wire single coils red/black/white - pretty sure white is hot (positive), black is ground, and I guess red is negative based on how they were wired originally.

It is a 5 string Ibanez Mikro so I'm not assuming they did anything wacky, looks more like just a standard VVT:

With the White wires going to the center terminal on the Volume pots.

Where on your diagram it looks like the Neck hot goes to one of the end terminals on the Vol1 pot:

bottom line, I only need to worry about your "red" and "purple" connections plus the black ground from Vol2 to jack, right?

I'm a computer guy, not a circuitry guy so I gotta break it down lol.
