Re: Pickup swap...RG570
What are the Black Winters lacking in your 570? I ask because I also have a '99 570 and a brand new Black Winter bridge PUP waiting to go in, as my 570 is taken apart about to get a new paint job (all prep is just about finished, going to start spraying it today). I haven't decided on the pots yet, I have a couple 1 meg pots I might use but I also have a no load I might use for the tone pot instead...
Also, how do you like the Tone Zone? I know Ibanez uses them as the stock pickup on some of the Prestige models. I've heard they can get a bit muddy, but the basswood of the 570 might balance that. Then again, so many people dislike the V8, but I love it. I have a DiMarzio D Activator in another of my RGs and I do like it, but I wanted to try something a bit hotter with clarity in my 570.
Anyway, I agree with Sepulchrave if you go with Blackouts (or any active) don't hook up the S1. If you stay with with passives, the DiMarzio True Velvet is a nice sounding middle pickup and 1 meg pots will give you a brighter sound (assuming you have the stock 500k pots in there).
