Comfortable wood handle. Individually poly bagged. Made in the U.S.A.No. 8020 tuning hammer. Review: Perfect for Pedulla Bass - Fits Pedulla Bass truss rods. Yes, there are cheaper ones out there but they never fit right and could potentially strip the truss rod adjustment. Review: Works great, good quality and fit. - Not sure what the other customers received but mine seems like it is superior in quality to those. Handle is sturdy and the metal seems to hold up. I've tuned and retuned the harp several times and it works like a charm. Fits great on my lap harp that is branded as a 'melody maker' and made in Romania. Smaller pegs than those on a piano or harp and this fits perfectly. Very happy with it. ## Features - Hardened steel shaft is chrome plated. Comfortable wood handle. Individually poly bagged.

My music maker has square pins that measure 0.165" and I know that some of the wrenches out there will not work.** A: the opening size is ABOUT 5/16" to 3/8" square....i just took a chance and bought the tuner for my unknown brand autoharp...and it fit! **Q: WILL THIS TUNE A 1959 Oscar Schmidt auto harp?** A: Do the tuning pegs have a squarish roundish shape? Like tuning pegs on a piano but much smaller? I'm pretty sure all autoharps have the same kind of pegs and this one should work. I say go for it. Get a 25$ purchase and shippings free for that item, kinda cool. **Q: Does this tuner work on the first act mg901 lap harp?** A: I don't know. It works on most brands of auto harps because the pegs for the strings are alike on most of them. So I would assume it works. **Q: Would this work for a 19 string pixie harp? The pegs are about 4mm or about 5/32". A little smaller than someone said 3/16" was standard.** A: I don't know what a pixie harp is. But when trying to tune my autoharp, the metal end that fits over the string peg split. I found it to be a piece of junk! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for Pedulla Bass *by A***R on January 17, 2026* Fits Pedulla Bass truss rods.
