I used the black Schallers to replace the stock chrome tuners on an old Fender acoustic. They look slick as heck, hold tune, and turn nice and smooth. I had to widen out the old post holes and drill new holes for the screws but since it's a kickaround guitar I had no problem with that. My only issue was that 2 of the threaded collars had burrs on them and were difficult to screw into the tuner housing. I had to force them very carefully so as to not scratch the black finish on the hardware. Hence; the four stars.

Schaller M6 Machine Heads

I use .015 -.058 gauge strings on resonators guitars. I always encountered tuning problems despite purchasing several name brands, as they exhibited backlash. I installed the Schaller M6 tuners in half an hour and the resonator guitar remains in tune. I'm ordering additional sets of Schallers for all of my other guitars. Thank You STEWMAC for stocking these ultra cool machine heads. They work!

Schaller M-6 Tuners

I installed these on a 1992 PRS Custom 24 in place of the original winged tuners. They are not locking tuners but the fit on the guitar was perfect. You do have to grind a little off the ears on the two top ones so they will fit under one screw which is exactly what PRS did on the originals. These are quality tuners and they are the only ones I've found that fit without mods to the guitar.
Service from StewMac was excellent also. Received them in about three days after placing the order.

Schaller M-6 Guitar Machines

I recently had a customer give me a good looking but cheaply manufactured LP look-alike to overhaul with quality parts. Naturally I chose Schallers for the machine heads!

Schaller Preferred

I've tried other tuners, some more expensive, some less. From now on, I'll stick with Schaller. They're great quality and look beautiful, especially the gold.

Replacement Machine Heads for Les Paul

I was searching everywhere to find a replacement set for the original machine heads of my 1979 Gibson Les Paul. Thanks Stewart-MacDonald for being there.

Great Tuners

I have had these tuners on 2 les pauls for years. So when I decided to build an acoustic guitar, these are the ones I chose. I like Stewart MacDonald. When I ordered the wrong set, they responded right away and helped me get the right tuners. Just like the Schaller tuners, StewMac is a smooth machine.

Sturdy Tuning Machines

I bought these because a guitar I was repairing had three busted tuning heads and I got them in just in time and they work very smooth. Only problem was I needed to make another hole because the sizing wasn't right, but that was an easy fix.
