I just put a pair of Fralin stock soap bar P90's in my Axis Super Sport. The original MM90's had been replaced with Dimarzio P169's when I bought the guitar. The P169's are 'virtual P90's' that are actually like mini humbuckers, so the silent circuit was pulled and they were wired to a 5 way switch. They weren't bad, but the Fralins's are just superb. My axis seems well shielded and the Fralin P90's are very quiet. I re-wired them to a tele type 3 way switch, and I am wondering if I should replace the silent circuit system of not? Any thoughts?
