These are the new Sperzel Trimlok EZ-Mount tuners, no need to drill your headstock! Satin Chrome, 6 inline and staggered/graduated.
The new Sperzel EZ-Mount system uses two tiny spurs instead of the traditional TrimLok pin or the screws needed on other tuners. No need to drill your headstock, just loose fit the tuners, line them up and tighten the nuts.
Important: Uses standard peg head holes, and is suitable for 6 inline headstocks - you should have a 10mm/13/32" peghead hole (most guitars have this), and your headstock needs to be less than 15mm/0.590" thick (most are)
We keep a massive inventory of Sperzel TrimLok guitar tuners, including the custom colors and 7 and 8-string sets. SportHiTech are authorized Sperzel distributors and all our tuners come direct from the Sperzel factory. They carry full factory warranty, and we don't just sell these, we use them as well on all our guitars. We're very proud of our customer service and our feedback rating, we ship really quickly, and we understand and use the products we sell.
