Decent budget option
theskirrid 31.05.2020
Good:-
This is a cheap and cheerful A440Hz [not adjustable] tuner with proper bypass.
Nice and quick to react, and makes it clear when a string's in tune.
Copes with Drop A on guitar, and B on a 5 string bass if it's first in chain, and happier with bridge pickup signals.
You know when it's on as the indicators can be seen from the ISS. It's also got a positive footswitch.
Tiny footprint on a board.

Meh:-
Clearly made in the same factory as EastRock, Donner and others, as it's identical, down to the magnetic flappy box. It also has exactly the same flaw, a loose jack socket. The hole in the case has been cut slightly oversized, so the socket is loose, but the jack itself is a good fit. Mine's in a pedalboard, so accidental disconnection isn't a worry.
Only powered by the socket [due to it's nano size].
No way to adjust frequency from A440HZ.

TLDR:-
Cheap, cheerful, fast but built to a price. Worth that price.

It's Still Working!

I've had a few cheap pedal tuners in my time. Usually they pack up within a few months, but this one has lasted a long while (probably around 3 years at this point). Sure it doesn't look the nicest, but it does the job, and is pretty durable. Would recommend!

good enough
james n 22.11.2022
I use it to tune modular oscillators , it works fine but sometimes it fails to identify the key on lower frequencies, but that ok, after all, its not designed for this purpose. Too bad it doesn't run on batteries.

Great price/quality so far
Cinnamon Moelleux 05.02.2023
Received one of these with a faulty display, but Thomann sent me a replacement very fast. It gets the job done very well (no twitchy meter or anything), feels sturdy, it's compact and the display is nice and bright!

You get what you pay
Lalinuss 25.11.2019
It is a good product, for the price.

PROs:
- very clear screen, green coloring helps a lot
- thin and feels durable

CONs:
- lights are veeery bright (like very)
- noisy click on switch
- input & output jacks offer some "resistance" when plugging and unplugging

What you see is what you get
Amyways 18.10.2024
It's a tuner that works. If that's your standard then go for it, you probably can't go wrong for the price.

As for the nitpicks, it's sometimes slow and takes a while to get the note I'm playing right. The button feels kind of cheap. The lights are nice and bright, possibly a bit too bright if you're looking straight down on it, but fine at an angle. They are a lot brighter than the display though, which is somewhat questionable.

Overall, obviously you won't be getting anything fancy for the price, but if you're just looking to get your guitar in tune then this will do the trick just fine.

Nice thing, took it off of my main board though.
Tooomas 16.09.2024
It is fast enough, and visible, small and cheap. I removed it from my main setup because it had a small unwanted effect on sound - might be the buffer, might also be just my ears. Now I use it at home and have no complaints.

Does the Job
TB TB TB 06.03.2019
I was in need of a tuner; didn't want to spend big on a big name tuner, and found this one. The display is good but not that good, if you have difficulty seeing things that are on the floor. The other thing is that it does not like tuning the 6th string; its' as if it cannot read the lower string so have to resort to the 12th fret harmonic. Otherwise, great for the price.

great quality product!
Lucas B 02.11.2017
this tuner is amazing for the price. it's really easy to use and does the job perfectly.

This Harley Benton CPT-20 is an amazingly good pedal. It's nice and small so it fits neatly on every pedalboard.
This tuner is really easy to use: just plug in a 9V adapter and your guitar, push the button and tune your guitar with ease.
The only downside I experience with mine is that whenever the lights switch sides (from too flat to right or to too sharp) they make some noise on my amp, but only very quietly (not as loud as touching your jack cable when it's not plugged in to your guitar)

Overall I couldn't be more happy with this tuning pedal. I would definitly recommend this to anyone looking for an affordable way to tune their guitar.
