hey David,
I put a Duncan distortion in my
Epi Lespaul custom.
and to be honest, i couldnt be happier. its tight, aggressive and clear, specially under highgain. installation was very simple and straight forward. after you setup and wire the pickup, the only thing left is to adjust its height.
Keep one thing In mind.. if you order a Duncan Distortion with a cover, it wont have as much output as the none-covered ones. the cover doesnt allow the coils to get closer to the strings, which wont give you as much output.
Cheers
