Schaller M6 135 tuner holes


New member
Hi there,

Does anybody knows  which tuner holes the Schaller M6 135 require? 10MM or the 11/32"? There is nothing at Warmoth's website about that. They seem to be perfect for Fender necks... but which one? I even read something about smaller headstocks... Crazy...

Yes you need the Schaller / Modern Fender / Sperzel (25/64" - 9.92mm) option that Warmoth provides. Here you can see Schaller M6 135 being installed into the holes...

When you mention perfect for Fender necks you would need to have a Fender neck with a modern 10mm bore. However a lot of those are drilled for two pin locators. If you want to put Schallers onto a two pin locator Fender neck you would be better off with the F-Series Standard + Locking which are a direct retrofit. Do not get the Schaller M6 Pin for a Fender neck as the location of the pins is different between the M6 and the Schaller F-Series.
