The configuration is not bad but far less easy than with the knobs as b2 in zoom shot is easily lost in all this. The tuner is not precise and is long and hard to access this that got me in great fear during a concert.
The manual is useless.
Let me be clear sounds are worthless even if we train at home and that we are not demanding the effects are zero.
"I use" (because in fact this pedal is so bad that I do not use m) this effect with a bass amp and a good preamp a high quality. In addition to the pedal is bypassed even if the blow is cut effects the food we pedal sound.
<span style="font-weight: normal;">I use it for two years and I regret my purchase even for € 25
The buttons are loose
I suggest you buy the home zoom b2.</span>
