OK so I want to replace one of my stock Ibanez SR885 pickup (ADX5) with a the Seymour Duncan Musicman 5er Replacement. I spoke to my luthier about it already and, physically, everything should work out (pickup placement spacing, string spacing, etc.. all compatible) but the thing he was not sure on is how my existing preamp in my SR885 will react to it. Anyone know if this can be done, any electronic problems, or ever do this before? Should we just contact Seymour Duncan? Any help would be appriciated..thanks!
