I can't seem to find a definitive answer on my own so I'm hoping somebody here knows. I'd like to change the stock duncan designed bridge pickup in my RR24XT and need to know the polepiece spacing. Being that it has a fixed bridge, am I correct to assume that I will need to purchase the non-trem spacing version of whatever pickup I decide to go with or is there more I need to know about the spacing? Also, anyone have an opinion of the Dimarzio Crunch Lab as I have been ready many good reviews of it? Thanks for your replies.
