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.

Really good value
Christopher7960, 28.09.2017
This is again another one of those products from thomann that makes you think why would you pay more for something else.

It turned up in really nice packaging, which is always a pleasant surprise when you buy a cheap item. Like the rest of the mini pedals out there, this runs off a power supply only, there's no room for a battery. The case is a solid metal, and we'll painted. The button is reassuringly sturdy and makes a nice positive click when you push it. The display is really bright, very be as you to see on a dark stage. The important part does it work? Yes, I've had no issues with it at all, it tunes perfectly every time, even when tuning very low it just works. I've checked it's reliability against a bigger and more expensive tuner and this one was always spot on, so I've since sold the more expensive one. It mutes the output when your tuning so also great for instrument changes while on stage

As mentioned the pedal is very small which I like, it means more room for pedals on my board.
Small form
Easy to use


There really isn't any

As I said at the start why you'd need to pay more a tuner overalls don't know, this one does everything you want in a cheap but reliable package.
