1. What onboard preamps do you use and do you run series or parallel? Im running in series and seem to be overdriving the input of my sadowsky pre. Sounds amazing, even the distortion sounds good in a GK GIVE kind of way. But id prefer clean. 2. My polepieces on the bridge pick have rough spots that grab my fingertip skin, are there and aftermarket polepieces that are really smoothly beveled, or any diy tips for msking them super smooth? Love these pickups!
