Grover 8020 Autoharp Tuning Hammer

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.

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.

I needed a truss wrench for my Pedulla bass guitar and could not find one. I tried several different sizes. This one works perfectly!

Make sure you get the right prong shape and size. It’s pretty easy to use after that.

Searched and searched for a better tuner for my Music Maker lap harp -- tuner provided is a flat piece of metal very hard to maneuver, which complicated tuning. This Grover 8020 tuner works perfectly -- easy to make those tiny, tiny adjustments when tuning this lap harp (and I'm guessing other small string instruments).

Tried taking an old Autoharp that grandma and grandpa bought at a garage sale and tuning it up. The trouble is that the strings are out of shape, corrosion, wear, and tension has made them untunable. The tool though is as expected.

I ordered this because the Oscar Schmidt autoharp I ordered at the same time didn't have one listed in the description. When I received the autoharp it was broken into about 100 pieces, so I returned it. I ordered another 'harp from another source and had to wait two weeks for it to arrive. It came with a tuning hammer. So, I figured I had a spare. Until I tried to use this one. This tuning hammer won't fit the tuning pegs of the 'harp I received. The hole/opening on this wrench is smaller than the wrench that came with my 'harp. And, it's malformed. It's not square, as the one is I received with my 'harp. After it didn't work, I checked the posted reviews. I saw some that said their hammer worked on Oscar Schmidt 'harps. I read others that said their hammer failed or wouldn't fit. Obviously, the quality control for this item is in the toilet. Don't make the mistake I made and expect this to work on an Oscar Schmidt 'harp.

If you are buying a lyre harp or autoharp, get this, even if one is included with your harp. This is a solid tool, not like the one I got with my lyre harp. I would have preferred wood, but it does the job well.
