Funny how this keeps coming up...
I also like JP's sound, and I think I have the same guitar as you. I bought mine in Japan while on vacation. I tried the Steve's Special but it sounded too harsh, whereas I love it in basswood. Currently it has an IBZ F2 in the bridge, a Virtual Vintage 2.1 in the middle position, and a
DiMarzio PAF (not the PAF pro, the original) in the
neck position. This gives it a very fat sound that also has a lot of highs due to the wood. Not too aggressive sounding though.
I'd like to try a real Tone Zone or a D-Sonic in the bridge position. Something else with more clarity for the neck too.
