Faster and More Accurate Tuning for Your Acoustic

Graph Tech's Ratio Acoustic 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 Acoustic 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 which 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 the Ratio Acoustic Tuned Machine Heads also work great on electric string sets with a wound G string.

Easy installation with no drilling

One of the greatest benefits of the Ratio Acoustic 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. As their name would suggest, the InvisoMatch mounting plates are completely hidden by the Ratio Acoustic Tuned Machine Heads and offer a sleek, low-profile look.

Graph Tech: improve your playing experience

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.

Graph Tech Ratio Acoustic Tuned Machine Heads Features:

  • Tuner machine heads that make tuning easier and faster
  • Each tuner reacts the same to the same amount of force
  • Also works perfectly for electric string sets with a wound G string
  • Classic design for a vintage appeal
  • 1 turn is approximately 1 whole tone
  • InvisoMatch mounting plates allow quick mounting with no extra screw holes

What is Demo Gear?

At Sweetwater, we're so picky that what we call a "demo" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

What demo means to us is that we've had it out of the box, or maybe it was in a customer's hands for a few days and isn't "factory fresh" as a result. Every demo item we sell has Sweetwater's 2-year Total Confidence Coverage™ warranty, and has been tested and verified up to "new" specs by our factory-authorized technicians to make sure it's in perfect working order before we ship it to you.

When you buy a Demo item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

Rated 5/5

Nostalgic gold look!!

These heads hold a tune to a pinpoint degree and even on the low E. They add to the depth and resonance in a noticeable way. They have an offgold kinda of bronze color which gives a throwback look. Get the black ratios for a more modern look.

Best tuners on market

I bought my first set for a fairly inexpensive takamine...they turn and hold like a dream.
So when i got a new martin, with the classic open gear tuners (no thank you), i just ordered my 2nd set.
I'd recommend these..i love 'em.

Best tuning machines I know of

I have tried them all. These work best for super accurate tuning, especially with crazy alternate tunings. Soon, all my guitars will be thus equipped. The only gripe is a small one: I would like a gold mounting plate to go with the gold tuners (but I get why they ship with silver ones.)

Nice upgrade

I purchased these as a replacement for a failed tuning machine on an Epiphone PR4e. They are almost half of what i paid for the guitar but the instrument has been super solid for me and i wasn't about to part with it. I really like the tuners, they seem to hold a very long time. The gold plating is a super cool finish and adds a very rich look to my instrument. They are just a bit heavy though and have changed the balance of the guitar. I play sitting so it hasn't affected me at all. Love the tuners, you will too.

Graph Tech Tuners

Replacement for my Yamaha LL16 stock tuners and they fit without any additional drilling. They are smooth and hold my guitar in tune. These tuners are really good quality and I would have given them a 5 but the Inviso Matching Plate's finish don't match the tuners. If you want matching Inviso Matching Plates you will have to order them through Graph Tech, and that's an inconvenience and additional cost. Other than that these are high quality tuners.
