ENO Music PT-21 Guitar Tuner


What is it?
ENO Music PT-21 Guitar Tuner, made in china 2013.

I wanted to try something tiny as a tuner for my personal pedal board. The price was one factor. I didn’t want to get another TC Electronic tuner as the old Polytune i have works reasonably well and i’m familiar with the use. Recently i’ve noted that i rarely use the polyphonic mode, so i was pretty interested in these new chinese mini pedals. First i tried it out. Works. Feels responsive.. A/B’d this with my old war horse, Boss TU-2. That Boss is the tuner i use at home for everything from re-stringing to fine tuning the intonation. TU-2 is good, responsive (sometimes too responsive) and very accurate tuner. This ENO is about as fast as TU-2, doesn’t go mad and doesn’t get mixed up in frequencies.


Opening the unit up shows pretty neat work. Everything has its place (ok, the couple red wires could have been replaced by better engineering). The rubber band making the DC jack fit perfectly made me smile. Simple solution, yet quite elegant. At this point i’m not getting deeper about how it works as it is digital design. Maybe i’ll revisit all the stub articles about digital stuff one day..


It seems like the ENO PT-21 is solid and well made tiny tuner pedal. I’m yet to test it on my own board, so we’ll see how it takes some real action – handling the temperature changes and if the frequencies stay accurate on real situation. For home use this cheap little thing seems to be a good choice.

Placed it on my board and used it for a few days. Even though it seemed to be as accurate as TU-2 in the first run, the Floyd Rosed Strat didn’t agree. It does get close, but not close enough. Sad. Sad indeed.

How does it sound?
It doesn’t. But it isn’t supposed to. It is true bypass though. But for the usage.. It’s not the worst tuner i’ve had by a long shot, but it simply isn’t accurate enough for me. Not bad, but i might sell it off rather than trusting it. Oh well. Guess i’ll just need to get that Polytune mini. On the bright side, this is definitely better than DOD FX12 Tuna.
