Hello, posting here because vguitarforums seems a little anemic on the V-Bass front... I picked up a GK-3B and a V-Bass (not the VB-99) on ebay, mostly to experiment with upright models. I put the pup on my Jazz bass and things seem to work pretty well. However, I'm having issues with the A string (and the E to a lesser extent). The G and D sound good, but the A seems to have this missing bit of dynamic range in the middle. It registers softly-played notes as soft; plucking harder still produces a tone and volume like a softly-played note; then suddenly it registers loud notes as loud (there's a similar problem with the E, but not nearly as pronounced, so it's a little hard to tell yet if it's something I can live with). (I THINK that describes it OK; there might even be some unevenness between a softly-played A string note and softly played G/D string notes, which you'd think could be compensated for with string sensitivity tweaking, but it's a little hard to tell.) So if you imagine graphing the response of the different strings, the G and D seem to have nice smooth gradations from soft to hard, whereas the A string might have more of an S-curve or a stair step (and the E string to a lesser extent, maybe). I think I've ruled out problems with the action (i.e., string-pup distance), as well as the sensitivity setting on the V-Bass (boosting the A significantly only seems to raise the relative volume without addressing the uneven response). I'm wondering if I have either a slightly defective pup (I suppose I could test by shifting it up/down one string, so the middle marker is either between the E/A or the G/D), or maybe the way I have it mounted is creating some strange resonance (or lack of resonance; I have (4) 1/2" x 3/4" tabs of foam tape evenly spaced along the pup holding it on, seemingly securely), or maybe it's something inherent in the bass itself (It's a Fender Jazz with a Modulus neck and a Badass II bridge). Or possibly some other adjustment I'm not aware of? Any ideas welcome!
