My Les Paul has Seymour Duncan Alnico II Pros in neck and bridge. I also have an RS Guitarworks modern kit installed. I only play with the tone knobs rolled all the way down to zero. Sounds great that way. If I turn the tone knob past 3 it sounds horrible. It sounds like I'm playing through an amplified transistor radio that is located at the other end of a drain pipe that runs under the road. I can't believe anybody could possibly find an application where that sound would be deemed appropriate. I've always avoided the problem by rolling the tone completely off. This can't be normal . . . or can it?
