These pick-ups are terrific. I researched pick-ups suited for jazz for a hollow-bodied electro-acoustic and, after looked at Seymour Duncan, Gibson Classic 57s, hand-wound, etc. and eventually felt that because a) there were enough good comments about Toneriders and b) they were just for a third choice Epiphone Dot Studio, these would be just fine. They're beyond just fine. Way beyond. The tone is smooth and clean but still with enough bite to give them some character. They take a clean sound nicely and even get some satisfying controlled feedback when overdriven (not always easy in a hollow-body).
