Faster and More Accurate Tuning

Graph Tech's Ratio Locking Tuned Machine Heads offer a revolutionary new experience in ensuring your guitar is tuned more quickly and accurately than conventional tuner designs. Each tuner in the set boasts a custom gear ratio that makes each machine head react the same — roughly one full turn per whole tone. Because each string reacts the same, not only is tuning a more pleasant experience, but nailing alternate tunings is a much faster process. Graph Tech's mission statement is, "To Improve Your Playing Experience." They've nailed it with the Ratio Locking Tuned Machine Heads.

Graph Tech's Ratio technology

Though it's a simple idea, Graph Tech's Ratio technology completely changes the way you tune your guitar. All six strings are outfitted with gear ratios that ensure you attain the same response from your wound low E string as you do your unwound high E. No matter what string you are tuning, you'll notice that one full turn of the tuner equates to roughly one whole tone pitch change. The Ratio technology makes nailing your pitch much easier and faster. And you'll love how fast it is to get to Drop D and other alternate tunings.

Easy installation with no drilling

One of the greatest benefits of the Ratio Locking Tuned Machine Head system is that they install onto your guitar's headstock without any drilling or other destructive procedures and are completely reversible. Graph Tech's InvisoMatch mounting plates ship with the tuners. The machine heads mount directly to those plates and aren't screwed into your instrument.

Graph Tech

Graph Tech has made it their personal mission to supply the products that will make your instrument play better, sound better, and perform better. From the company's popular String Saver saddles to their TUSQ string nuts that can be found on countless manufacturers' guitars, the company's products are a mainstay in the guitar and bass industry. Just about every player at Sweetwater owns something created by Graph Tech, because — like their mission statement demands — they never fail to improve our playing experience.

Great so far...

Had many guitars in my lifetime but none that had locking tuners...was on fence which to get...so i talked to 1 of the sweetwater reps about em and he has them on his ax and loves em...so why not...i ordered them...when they arrived and i read the installation directions they made it sound very complicated and drills needed and all that krap...said screw it and chucked directions in trash and applied common sense...installed quickly with no drilling...will give another review down the road to see how they hold out...great looking and luv the gear ratio set up...thanx sweetwater for advice...!!! You guys have been a lot of help over the years and thanx...

Graph Tech PRL-8341-C0 Ratio Electric 3+3 Locking Tuned Machine Heads - Vintage Style / Chrome Finish

These Locking Tuners are awesome, There is no slippage whats so ever since they make the gears with the specific strings. The gaskets that come with the tuners will fit almost any guitar, even the older models, In some cases you may have to mike the holes alittle bigger but again it all depends, my 2013 Epiphone Les Paul i had to, but well worth doing so.

Great Locking Tuners

Love these new locking tuners. All guitars should have these. Install was easy. I was really lucky that I didn't have to enlarge the hole. These fit perfectly. Also, the back plate fit perfectly too. I kept the original screws. Took me about two hours. Went very slowly b/c I didn't really know what I was doing, plus it was dinner time. They're a little heavier than the originals I took out, but it's not noticeable. Not top heavy or anything.
