Dear Dale Neither repinning/nor renotching, etc made the difference that WAPIN did on our S&S D. We tried the repinning/notching route first, and yes, we got some improvement....but w/WAPIN it was dramatic, and not the same as you would get w/just a repin/notch job. Sustain/and volume are greatly increased. You have to go hear/play one to really appreciate it. Regards, Rich A.
