Make Sure Your Guitar is Tuned Correctly Each Time!

Keeping a guitar with a tremolo bridge tuned can be problematic. Sperzel Trim-Lok tuners eliminate tuning issue without tone-killing locking nuts. Change strings in seconds on any guitar with these tuners. Simply insert the string through the tuner eye, pull tight, tighten the locking mechanism of the tuner, and then tune to pitch. It is that easy. The locking system quickly locks down the string ensuring a non-slipping, stable string winding. You'll love the tuning stability of Sperzel Trim-Lok tuners!

Sperzel TrimLock

Kinda pricey, but you get what you pay for, right? And these are well worth the cost of having no more tuner problems. Plus, they make string changing a quick chore. If your putting them on a Fender product, (which these are made for), the only hole you have to fool with is the small pin hole, which sits between the two stock pin holes. That way, if you ever want to go back to the stock tuners, the new hole is hidden. If Fender would drill the third hole for us, these would be a drop in replacement. But,...that aside, an excellent upgrade.

Best money ever spent to keep my Strat in tune!

I struggled for months to keep my 2013 American Standard in tune, but no dice. I was about to sell it and get a Gibson until I tried one last effort to save this guitar. I really like the tones I get out of a Strat, and as a last ditch effort, I spent the money on this tuner upgrade, and wow - what an improvement! My guitar stays in tune day-after-day, and I'm really glad I installed these tuners. Why Fender doesn't get their act together and use these machines (or go off and develop their own) is anyone's guess, but like they say - out with the bad and in with the good. The only downside of this upgrade is that the folks at Sperzel don't use the existing footprint of the Fender machines, so you will need to drill six holes to match their tuner pins. The whole installation took me about 45 minutes, but it was well worth it. They work.

In tune at last!

I've been struggling with keeping a 2013 American Standard Stratocaster in tune for months. I play a lot of blues with plenty of string bending and I needed to retune my guitar constantly! What a total drag.... I was getting really discouraged until I read about "locking tuners". I love my Stratocaster but didn't want to move to another guitar just because of the tuning problems, so I took a chance, bought these machines and all I had to do to make them fit was drill 6 holes into the headstock to accommodate these Sperzel machine heads. A bit of a hassle - why don't they accommodate the holes that Fender already uses!!!! However, the kit came with a template so it wasn't a big deal. Now for the really great news - since installing these tuners, my Stratocaster has NOT gone out of tune since! This is a HUGE deal for me because I was ALWAYS having to retune my guitar each time I used it - sometimes a dozen times a session, and what a drag that was. I cannot recommend these tuners higher, and what a bloody shame Fender gives us crappy machine heads to begin with! For now on, I will replace any Fender tuners that come with my Strats with Sperzel's ASAP.

Great Tuners

I'm very impressed with the quality and the functionality of these tuners. A night and day difference from the original tuners on my American Stratocaster. These tuners also were a breeze to install on my Stratocaster.

Sperzel tuners are a lifesaver. I love Strats, but I also love my whammy bar. I installed these on my Strat, and I can dive on the twang bar all day long... and my Strat stays in tune!!! It also makes string changes much easier. I love my Sperzels, they saved the day!

Sperzels are one of the best upgrades you can make to any guitar. Better tuning stability and faster string changes. I will never have a guitar without locking tuners again.
