The Planet Waves Auto-Trim Tuning Machines automatically cut off excess string while you tune up your guitar. An individual string clamp holds the string tightly in the tuner, so there's no need for multiple wraps around the tuning post. A precision 18:1 gear ratio provides smooth, exact tuning, while virtually eliminating backlash and slippage.

The rugged, die-cast outer casing houses precision 18:1 bevel and worm gears, a string clamp, and a hardened-steel wire cutter. Restringing has never been easier: simply insert the string, tighten the clamp, and tune up. The Auto-Trim Tuning Machine does the rest.

Great tuners...

By Troy Wheeler

from Roseville, CA

I bought these tuners for a build that I'm working on after reading some great reviews about them, With 18:1 ration they're super tight and easy to find the sweet spot. The other really cool thing was that I contacted the good folks at planet waves (D'Addario) because the neck I have had a 4+2 Holdworth headstock. They offered to send me the extra tuner for the treble side at no cost! That's awesome customer service! I sent them the receipt after buying the 3+3 set and had the extra in my hands a few days later.

just one loop

By Rich Ott

from Huntsville Alabama

I had the same B and E string problem slipping out and found using 1 loop around the post eradicated the problem. Not a perfect situation but its a solution. The reason I gave it 5 stars is because it IS a trim lock tuner, it IS an 18 to one ratio tuner and it IS about half the price of sperzels tuners.

Excellent Tuner

By Michael Wamback

from Venice Beach, CA

Wanted to upgrade the stock Grover tuners on my Epiphone Les Paul. After much research, decided on the Panet Waves. Very happy with the choice. They are pretty much a direct replacement for the Grovers. They are just a hair smaller, but I was able to install them without drilling new holes for the screws. Tuning is awesome now - very smooth with the 18:1 ratio. They also seem very well constructed. Hold the string tightly, and the auto trim feature is really cool. I use a 10 gauge set, and trimming the low "E" took a bit of pressure, but nothing unreasonable. Not sure I would want to use it on really heavy strings though. Hold the tuning very stable, and the black set look really nice on the guitar. If you are considering upgrading your Grovers to a locking set, this is a pretty good choice, especially for the price. Will see how they stand up over time. The only issue I had is that the screw on the back is very close to the tuner compared to the Grover, so you really want to have a proper screwdriver with a thin shaft so you don't strip the screw heads when installing. (I also found it helpful to lube the screw a bit with soap, since it is a tight fit as the hole isn't 100% perfectly aligned with the hole used by Grover - so it's a tight squeeze.)

love them


from las vegas nv

I believe these are the best locking tuners, and I love the fact they cut the string. I have them on all my guitars, never a problem, always holds the strings

Works Great!

By Kirt Frischknecht

from Arcata, CA

I installed these on an older guitar with cheap tuners, so I had to drill out the headstock holes to fit them. My headstock was probably thicker than usual, so I couldn't use the washers and nuts provided. You probably won't have this issue. It didn't matter, the tuning keys worked just fine without them and now my guitar stays in tune like I always wanted. The finish looks great and the fact that they lock the string and cut it is gravy. I have never changed strings so easily.

Very Nice

By Christopher Nelson

from Austin, TX

I love these things! I was a little skeptical based on some of the other reviews, but I must say I am more than pleasantly surprised. I fully expect designs similar to this will become the standard in the future. I decided to put them on my Martin OMC-1E. They didn't fit the stock holes on that guitar, so I had to do a slight modification using a Dremel sanding bit to make the holes a uniform diameter, but that will surely vary from guitar to guitar. Stringing the guitar with these babies installed is a cinch, but the included instructions leave a few things lacking. To clear up that and some of the issues stated in previous reviews, these are the steps I use. I'm yet to have any issues using this technique. 1.) Insert the strings in the bridge and insert the bridge pins. 2.) Tug each string toward the nut to make sure they are seated snug in the bridge with no slippage. 3.) Turn all of the machines so that the side with the silver metal bump is facing the neck. 4.) For each of the strings, insert the string into it's assigned tuning peg through the side with the metal bump. The direction is important. Pull the string all the way through until it is straightened. You don't have to leave slack like you do on normal tuning machines. 5.) IT IS VERY IMPORTANT NOT TO UNDER-TIGHTEN THE STRING HOLDER KNOB. Tighten the string holder knob to lock the string in place. Tighten it as tight as you can with your fingers and pull the string back toward the bridge to test for any slippage. I am able to get it tight enough with my fingers, but as a previous poster said, you might also consider using pliers to give yourself a bit more leverage. You don't have to kill it, but you do need to make them nice and snug so the string cannot slip out. 6.) Turn the tuning knob to start tuning the string. Once it reaches the cutting edge the string will be cut very easily. 7.) Once the string is cut, TIGHTEN THE STRING HOLDER SCREW AGAIN! Some of the resistance is released once the cut happens and you'll be able to tighten it a little bit more. I believe this is probably the root of the problems others have had with string slippage. 8.) After you have all of the strings in and cut, tune all of the strings up to full tension. After you've done it once you will be able to change all of your strings in a couple of minutes.

Easy string changes

By Jess T.

from Bedford, IN

Strings changes are so much easier and quicker with these things and they even make tuning easier and more precise. I put them on every guitar I own.

By NatMan70s

from West Allis Wisconsin

I bought these tuners for my 81' gibson Sonex 180 Deluxe. At first i thought that these tuners would be cheaply made. ThenI was amazed at the quality of these tuners.These just slipped into the peg hole that were already there. So There really was no need for drilling and such. The cuting tools on these really blew my mind. The finish is the cherry on top. Great Job Planet Waves.

You only get one chance...

By Joe

from Grand Rapids, mi

The design is SO cool but you only get one chance to get it right since it cuts the string off so close to the tuner. I had one string pull through and I had to throw it away because it was too short to feed through again. Be SO careful and lock the strings down HARD.
