Hey Bjorn. This changes the control layout to give you individual tuning control over the 2 double tracked voices. It sounds good, very good.

Have you tried the Dimarzio Chopper? Both have a very strong signal so the intricacies of lower impedance pickups are not present.

The EP booster is one of my favorite pedals. Hi bjorn Just wanted to thank you for your help in helping me decide on the emg d20 pickups.
