Autoharp etc. tuning key/wrench/hammer.
Trophy Music Company #8020, AKA Grover #8020
Fits Oscar Schmidt Autoharps and RBI ChromaharpsGUARANTEED!
I have also sold many in Europe and the 4.5mm square hole seems to be the worldwide standard for this type of tuning peg
Has square opening for tuning the standard square \"friction pegs\" found on many stringed instruments, even oddballs like Violin Uke & Tremoloa.
4.5mm x 4.5mm square opening on the wrench. (about .17\" x .17\").
I have never had one returned because it did not fit an autoharp. For any other instruments with square pegs, it should fit. I take returns if not.
This will ship USPS First Class, and I always try to shipsame day (please check my response score & rating)
Thanks for looking!
