Phase III Locking Tuners

Filed Under Acoustics / Electrics

Every part of a guitar has an effect on its overall tone. Anything a string is attached to will drain energy away from it.

Let’s consider tuners. Tuning pegs are one of only a few parts that a string actually touches, so they’re very important. If we made the entire tuning peg out of silicone rubber, would the guitar sound better? That question is an exaggeration to prove a point, which is: every single part of a tuning peg has an impact on the sound of the instrument and the tuning stability. A guitar with rubber tuning pegs would sound lifeless and have little sustain.

Our new Phase III machine head was designed and built with two goals in mind : One, that it doesn’t detract from the tone of the guitar and allows the tone woods of the neck and body to do their job, which is to be musical, and two, stay in tune while maintaining a highly useable gear ratio.

On a purely aesthetic level, I believe these new Phase III machine heads are handsome. They also sound great and just plain work. For those of you that don’t like change - get over it! I am confident that once you spend time with these new tuners, you’ll feel the same as I do.

In addition, I’ve heard that a few people have asked if the tuner’s open back design might be susceptible to dirt and wear prematurely. Absolutely not. Look back at all the old, high-quality instruments through acoustic guitar and bass history. History is very favorable to open back tuners.

I have a reclaimed semi hollow CE24. Whenever I take the guitar in and out of the gig bag (I'm a professional musician and this happens several times every day), the 3rd and 4th strings are out of tune. Literally 9/10 times. Also, 10% of the time the thumbscrew for the 1st string comes loose enough where there will be no tension on the string whatsoever. I have to get the string back up to pitch as if it were a new string. I'm very happy with the guitar itself, though these tuners are unacceptable for someone in my position. Can the thumbscrews on top of the post be removed so that the tuner can be used like a schaller-style tuner?

Hello, I have an SC245 and I would like to change the tuners to locking tuners. Does PRS make locking tuners that will fit this model? I know the screw holes for the tuners on the SC are different than the custom 24 I have. Your help would be much appreciated. Thanks in advanced!

Do you have any description for restringing with Phase 3 tuners? I found no "how to" videos on You Tube, and the photo step-by-step on this site is for Phase 2 tuners. I have a new 594 doublecut and dont want to mess up the tuners. Thanks, Jim

My PRS David Grissom has some tuners on it that are really a hassle to keep the strings in tune and they are very sketchy as far as approximating the note you want to tune to. As you get close you can easily overshoot the right pitch and have to start over with this endless winding. I really don't like them and i'd wish to switch them for the Phase III's/. I sent an email about this last year and got no response (EB). Could you please advise me as what you'd recommend? Thanks!

Hey Dr. LaRry, I would suggest contacting our customer service department - they may have some advice about the stiffness in the tuners. You can reach them at [email protected]

I got a 2012 Custom24 10-Top and the tuners turn really stiff ? I tried loosening the button screw but it spins as hard even with the screw all the way out ? Is there a shim I need or what ? Plus, I hate the bend in the tremolo spring on the straight end that goes into the tremolo block, makes removing them nearly impossible and it left damage on the block from the 5 minute struggle to remove it

Hey John! Hope you are enjoying the SE 245 - I bet it looks great in spalted maple. The tuning issue you're experiencing could be related to the strings being pinched in the nut. E-mail our customer service for some set up tips, or for more information about how locking tuners would work with the SE's. You can reach them at [email protected]

I recently purchased a 245 SE spaulted maple PRS. Sounds great with upgraded P90's. Problem is it will not stay in tune at all. I would like some locking tuners. Any suggestions? If not, any regular tuners that are more reliable than what came stock?

1996 custom 22, stoptail. Will phase iii's be correct height, angle and help with sustain? Also, I was considering changing the stoptail to the adjustable stoptail Bridge, will that enhance sustain and more flex In the strings? Lastly, everything's original. Since everything's from 96, is it time to change the nut? Never heard that addressed before. Thanks Guys!

Dose PRS have any locking tuners that fit an SE 245
James LaRocco July 31, 2015 - 4:36pm
Never had any tuning problems with any of my PRS USA Guitars. Its the way you wrap them that can make them move if they do go flat.After stretching,and playing they usually stay in tune.

I have a Dave Grissom model PRS and i really hate the tuners. Thinking about getting the Phase IIIs. Will they work on this model?

I recently purchased a PRS Singlecut Semi Hollowbody. Love my guitar excellent to its core. But it's a pain to keep in tune I think it's got phase II locking tuners and it's a pain tuning all the time. My Gibson's don't have this issue. Should I upgrade to Phase3 tuners? Thanks.

I need to replace an ebony tuner for my PRS Custom 22. It is around 2006. I'm not sure of the phase tuners and of the differences. Can you please point me in the right direction?

Just bought a PRS Artist IV with the locking wing tuners. This is the third addition to my collection. Also have a 513 and an SE which is what promted me to grab this one. The biggest nightmare of my life came when I changed the strings. I wasn't aware that I needed a phd in string changing. Will the Phase III fit on a 1996 Artist IV without altering anything else???
Eric Martin January 31, 2015 - 4:58pm
Hi, Same question, different guitar... I have a PRS 513 that has the closed tuners. They are very loose and I happen to have a bear of a time keeping it in tune. I'm thinking the tuners, perhaps? Would these new Phase III's help? I've had the guitar set up by a great shop, and still issues. My 2005 Custom 24 however is rock solid. Thanks!
