and be SURE that whatever tuner you get allows for a plug-in input, so you can use an inexpensive little gadget that clips to a post on the 'harp and allows you to tune even in a noisy environment!!It is nothing more than an alligator clip with a 1/4"RCA plug , but it saves you hours of aggravation, I used to have to go off in another room to tune till someone gave me one of those.
