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.

Not really True Bypass
EvanderVee, 16.08.2020
It's a very simple unit, one butten for on/off and a screen and some LEDs for tuning. The tuning (what it's designed for) is okay. More expensive units are probably more precise, but for home use it suffices.

Pro's:
The unit is cheap, small and easy to use. The screen is nice and big and tuning it this way is good to do. Besides it looks quite fresh.

Cons:
The red LEDs are so bright you can't look at the unit without eye dameage. I had to tape them off to actually use the unit. Who designed this??
But the biggest issue: The unit distorts the sound in bypass mode! When playing a bit hard on my single coil guitar it distorts. I can imagine this being a far worse problem on humbucker or active guitars. Therefore I'll be putting it behind a true bypass splitter I still have lying around and would not recommend this unit for whoever wants to use it on a serious pedalboard.

Does the job, could be made better
Chaosstar, 26.01.2018
CPT-20 works well. Screen turns green and stays green when string is in tune. If it won't stay green, it's the string, not CPT-20.

I have about five Thomann CTG-10 Clip tuners, so the screen was quite familiar. I consider CPT-20 like a CTG-10 in the pedal form. Nothing bad about it. I can still see the screen w/o my glasses while standing. Just about.

I also have a few Thomann CTC-50 Red tuners in my concert guitars cases. I find CTC-50 superior to CTG-10. I also have a Behringer rack tuner, which works well. The rack tuner is plugged into the recording out of my M/B Quad preamp, so I can't mute while tuning. That can be annoying playing live. I only use it during concerts if there is no other way. With clip tuners I can tune in silence, but I like to have another option for tuning in silence on the pedal board.

So I was looking for a cheap tuner/mute button with a small footprint to save precious space on PB. And CPT-20 would actually be a great choice if only a bit more attention was paid to details. The power input is like really loose, it moves into all directions. Not just a bit, more like 2 mm wiggle room. Also the switch feels cheap. It's also just a bit low, I used a S-Connector between a small buffer pedal and the CPT-20 and it's not a perfect match. The absence of battery does not bother me at all. The thing I really like was the brushed aluminum face of the pedal. More pedals should be like that.

All in all, could be made better. But it works. We'll see how long.
