I use it for 4 years, I like the price, $ 15 CAD, I also like the input and output, we can put it in a pedalboard, there is no mute, but it was not always adbrancher of the amp, plug in the tuner, a guitar tuner, plug in the amp. we only influence power, one tune, then reps on power.
I have since I play guitar, I did not try other models, the ratio quality price is right, he trs well for two and a half years, but after s he has done anything, it freezes, it is wrong rope, etc.. I will replace it with a kind boss tuner TU-2.
