I installed one on my handmade guitar on the advice of the guy I bought it from. He tried one in a Gibson and thought that the sound "Opened up" with a bridge doctor. I think that he was right. My guitar sounds much more balanced across the entire range, with what sounds to me to be additional "chorus" in the acoustics.

I feel that I've lost a bit in volume, but the guitar was a boomer to begin with. It suits my fingerstyle playing much better.

I give the bridge doctor a thumbs up.
