It's very bassy sounding, as you might expect given the pickup location. It's unmistakably a p-bass, just a thumpier version. It's as different from the split coil p-bass sound as a single-coil p-bass is...yet you can tell all three are p-basses. This is through an Ampeg V4 with 2x15. It has a little more definition through my Workingman's 10. In about 2 hours I go to rehearsal and will try it through my SVT 4 Pro with two 4x10 cabs -- hoping that set up gives it a little more articulation.
The stainless steel strings that come on it are really affecting the tone right now too. I won't really know how it sounds until I get my regular strings on it, mess around with pickup height, and try it through all my amps a lot more.
