I’ve now used the Mandolin Mic and am very happy with it. I used it through one of those Bose PA’s that has a subwoofer and a thin speaker stack and it worked well. It cut through nicely and was loud enough to be heard with two electric guitars and a bass without any feedback issues. I also used it in church yesterday through a Fender acoustic amp and it worked well there too.
Thanks for building a good product. It's especially handy that I can use it on any mandolin I happen to be playing. -- Jay Jessup
