I've just installed this configuration into my MIM P bass. The difference in sound is minimal, one slightly softer and thinner than the other. However, it still retains very much the sonic characteristics of the middle position p pickup. Im wondering 1) how this squares up against the different settings in the S1 P bass. 2) Has anyone who has done this mod found it to be useful? I don't see much difference in tone lean towards one setting over the other. Rather, I see it more as a 'added boost' switch What are your views?
