What is the opening size exactly? My music maker has square pins that measure 0.165" and I know that some of the wrenches out there will not work.

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!

WILL THIS TUNE A 1959 Oscar Schmidt auto harp?

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.

Does this tuner work on the first act mg901 lap harp?

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.

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.

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!
