Great sounding pickup. I have been using this pickup for a year with my RK-35 resonator banjo in a full band with drums. The piezo pickup I used previously used to pick up the drums, but I have had zero problems with the Myers mic. Once being set up to find the sweet spot, it sounds very well and keeps much of the original banjo sound. It
Mine is fastened with velcro (kardborre), so it is easy to remove and reattach to the banjo. The suction cup did not work with the round body of my banjo, but I would believe it works well on a flat surface.
All in all, I am very happy with this pickup. Easy to attach and sounds great with any string instrument I have tried it on.
