POLYTUNE CLIP Clip-On Tuner with Polyphonic, Strobe and Chromatic Modes and 108 LED Matrix Display for Ultimate Tuning Performance

I really like this tuner. The led display is very bright and highly visible. There seems to be ample space between the clamping jaws for thicker guitar headstocks. I am still running on the original battery after several months. This tuner is highly accurate and very responsive. My favorite part about the tuner is the metal clip. It is durable and will not break like the plastic clamps on other tuners I've used and had to throw away in the past. The simultaneous multi string tuning capability is a neat feature but I don't really know how to use it. I think the best feature of this tuner is the strobe tuning mode.

I've only owned Snark & the knockoff electronic tuners, which are very useful & economical. But when playing with my friends who use Petersen tuners, I wasn't able to tune to the same accuracy as them. Then I discovered this tuner, which can show the tuning status of all 6 strings simultaneously! This may seem like a gimmick at first, but allows you to strum all strings at once & QUICKLY see if any are out of tune. This tuner also responds faster than others I've used, so I can tune quicker. The display is very bright & easy to read, and I have not experienced any glitches or inaccuracies with it yet, unlike my cheapie tuners.

Brightest. Tightest. This is the best tuner you can buy right now. I'm buying 2 more. Great seller. At first, when I first got it I thought it didn't work but it was MY mistake. The thing's perfect and has ruined me for other tuners. They make perfect gifts for guitarists. I haven't been paid for this gushing review — I'm just in love!

This is my first clip-on tuner, and I think it's pretty great despite not having anything to compare it to. It seems to be every bit as accurate, quick and easy to use as my Polytune 2 pedal tuner (which I also really love). The polyphonic mode isn't as accurate as when you check each string individually (in fact, yes, the modes appear not to agree perfectly sometimes, as one guy who gave it two stars noted), but the polyphonic function gives you a quick and easy way to see if a string is so far out of tune that you should take the time to adjust it. One strum across all the strings and a quick glance is all it takes to see where things are at, and it's a super fast way to tune all your strings at once if you're in a hurry and don't want to tune each string one at a time to perfection (and if you do, then you may also suffer from OCD). Strobe mode is very accurate, but a little trippy to decipher until you get used to it, then it's very fast (also sort of space-age and fun). When deciding to purchase this I read some reviews that complained that they didn't like the clip, but I don't agree with them. It appears minimalist, functional, and robust. I'm not sure what those other folks expect. From an aesthetic design standpoint, this tuner is a lot less obtrusive and far more slick looking than the other options out there. One guy said he was afraid it could scratch his headstock, but I think you'd have to work at it pretty hard for that to happen. I also read some reviews that complained that the PolyTune Clip was a little fussy about where it's placed on the headstock in order to read all the strings. I found this to be somewhat true, but not an issue for me since it works great on the end of my Martin acoustic headstock, and in the middle of both my Fender Stratocaster headstocks (though not as well on the tip of the Stratocaster headstock where it's harder to see anyway). Others complained that since it doesn't swivel in all directions they didn't like it, but I've not really found that to be a problem for me since the best placements on my headstocks also happen to be in places and at an angle where it's easy to see. I also suspect that if it had another point to swivel from it may not be as accurate and sensitive as it is since more rotating parts means more places to negatively affect the vibrations it's trying to sense. In order to get the most out of it, you probably need to read the manual. I suspect some of the negative reviewers aren't big on doing that, and that's why they're happier with the less expensive clip-on tuners. Or maybe they just got a defective unit, who knows.

Very good tuner

The Good: First off, as a tuner this guy is very accurate, right on par with my Korg chromatic. The polytune feature is fantastic, you just strum evenly and you see the tunings on all strings and which ones need adjustment in an instant, I can't tell you how handy that is, where has this been all my life? The Meh: I only have a couple minor issues with the design, which I'm taking a star off for, but with some easy fixes this could be the best clip on tuner on the market. I like to suggest a fix when I complain about something so here we go: Issue #1 is the clip. It's metal with some rubber feet on it, kinda like the clip that holds your garage door opener on your sun visor in the car. Maybe I'm just paranoid but I worry about the pressure that metal clip exerts on the headstock and also that one of the feet will come off an I'll be gouging an expensive guitar with a bare metal clip. The Fix: Change the clip design to be softer, change the metal to some kind of plastic or rubber. Issue #2 is the button on the top. You use it to turn the tuner on and off and I can't feel it and it's all wobbly and awkward trying to push a button on top of a long skinny tuner at the end of your headstock. Just move the button to the side and make it more tactile. Overall: I really do like this tuner and it's probably going to be my main tuner at home, I'll buy one of the polyphonic pedal tuners for stage now that I know how awesome they are. Just fix the flaws on this clip-on and I'll buy another one, I promise!

My main tuners for years have been a Peterson Strobo-Flip, the iStrobo-soft app on my phone, and the tuner built into the NI Guitar Rig plugin. Both tuners are very accurate, but I find both mildly inconvenient. The Flip because you need to grab a cord and plug in, which is fine when I have it on my board as part of my setup, but if I just pickup a guitar at home, it's a nuisance. The app is limited because I use the phone mic, so it's of limited utility for electric, and acoustic requires close physical proximity to the mic. The plugin is fine when I'm using a DAW and electric guitar, though I remain a bit skeptical of it's accuracy. The TC Polytune is excellent in both it's accuracy and convenience. It took me a bit to get used to the strobe mode, as it's a little different the way Peterson handles it, but I only use that mode now, as it's super accurate once you get used to it. The standard chromatic mode spec is ±0.5 cent, while strobe spec is ±0.2. The only inconvenience is not having ten of them for all my guitars. The display is big and easy to read, and the clip and hinge allow a wide variety of positions, both in front and behind the headstock. The polyphonic mode is kind of handy for a quick reality check, I usually give the open strings a quick strum before I start tuning, and again after I've adjusted each string. The open question is durability of the clip itself, but I'm hoping for the best, and it certainly seems robust enough. I'll probably still use my Peterson Flip to intonate my guitars, but the TC might even do a good job with that.

I’ve owned quite a few tuners over the years. I was playing at a friends house and had neglected to bring my own tuner. He handed me one of these and I ordered my own that night. Just clamp it on the headstock, turn it on and tune. It doesn’t require a direct line in to be able to tune easily, quickly and with pinpoint accuracy even in a loud environment. The readout is bright and easy to read. It has a very large and simple readout fir being something the size of a thumb drive. I mostly play acoustic and I can just leave it clamped on the headstock folded out if the way. (It collapses flat onto itself). It’s not big and clunky or in the way at all. I don’t even notice it’s there until I need it. You can do a variety of tunings with it so it’s not just a tuner for standard tunings. This really is the only tuner you’ll ever need. Of all the tuners I’ve gone through in my over 30 years of playing guitar, it’s nice to find one that finally got it right.
