The string posts on 6-in-line sets have graduated height (no string trees needed). Cast gear housings with sealed lubrication. Single pin mount keeps tuner from rotating, no mounting screws needed. Recommended for 9/16" - 11/16" thick pegheads.

• 12:1 ratio
• 10mm (13/32") diameter pegholes required
• Removable metal knobs
• Threaded peghead bushings included
• Sets of 6

Staggered string posts:
The Sperzel 6-in-line tuners feature 3 heights of string posts in each set. The tallest two tuners are used on the E and A strings, the medium length posts are used on the D and G strings, and the shortest two posts are for the B and E strings. This allows the E, B, G, and D strings to have a steeper angle off the nut than with traditional tuners — eliminating the need for string trees.

To be sure these tuners fit your instrument, compare your existing machines and peghole dimensions to our listed specs to help determine the best replacement.

Don't love the Sperzels

I bought Sperzels for my Strat in 1985 when I read Keith Richards was using them. Were always fine. I don't really like these Sperzels. The action varies among the tuners and is not smooth, especially when tuning down. These tuners also made me realize that I don't like locking tuners in general. Now that I have an electric string winder, I prefer the more traditional tuners. I really like the Grover Rotomatics. They also have a finer tuning ratio-- 18:1; rather than the 16:1 of the Sperzels.

Great improvement

i have replaced the tuners in my 2001 MIM strat with satin chrome and boy what a difference. Rarely goes out of tune, easy to adjust, easy to replace strings, no need for string trees and in my opinion looks beautiful. Recommended! I ordered it through regular mail and it arrived in just two and a half weeks great!

Sperzel 6 in-line

One of the six has a a gear mesh that's a bit rough, which is surprising, but these things are excellent. The graduated height is fantastic. Never liked string trees, even the roller ones.

Best. Tuners. Ever.

These are my favorite tuners. The cardboard template is a little dinky, but it's accurate. Stewmac makes a jig for drilling a hole to accept the mouting pin. What I do is just eyball it with the cardboard template. Comes out good for me. Good weight, very sturdy, GREAT matte finish, the locking pins have never slipped on me in the 15+ years I've had them on my V. Best. Tuners. Ever.

Nice tuners but lousy template

Very nice quality tuners that I have on many guitars. The supplied template is not very good though. You must be very careful drilling the pin hole. My first attempt did not go as planned and I used the template.
