Well that's one good way to listen to the bass runs in a tune. I have been working on the tone for the last year playing in a tribute band. I didn't have to work too hard at it since it's close to the same tone I have been usuing for years. I have however gained much respect for JPJ. He gets many different tones for different songs. A little more highs, sometimes distortion, mid growls, and at times lots of low end. With a jazz bass and DiMarzio pups, an added Steve Harrris P neck that's nice and thick, I come pretty close. I also use a 62 AVRI P bass for some tunes. Some fretless work thrown in on my Alembic works well. Last night I tried a Hot Rod P/J bass and it sounded awesome. Just backed off the J pup about 25%. I use a combination of a 69 SVT amp or my Messa 400 with a sealed 810 ampeg cab and a 410 ported ampeg stack. The rest is in the fingers. I will apologize in advance for this crappy flip video quality. It was shot in a bar last week. The bass is a little hard to hear if you don't turn it up on your eq.
