CPT-20 : great quality product!

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.
