I have a Pedulla Rapture 4 string with the single Bart soapbar. It seems I can never get it to sound right. If I adjust the pickups to the 1/8" from the strings as recommended on the Pedulla site, the sound is more balanced string to string, but it sounds thin and has no bottom end. I get a pleasing fatter sound by raising the pickups and boosting the bass knob almost all the way. The E and A strings are warm and fat, but the D and G strings virtually disappear. I have thought about a Bart quad coil (couldn't find it on their most recent site...but I THINK I've seen it in the past.). The concept would be to wire the two E and A string coils in series and the two D and G string coils in series. Each coil set would have a trim pot to balance their outout levels. They would then be wired in series again to the volume pot. Two questions. One, anyone else experience the string balance problem with the Rapture? Two, anyone ever wired a quad coil config like my crazy idea above?
