Analog reverb pedal in true bypass. We find a volume knob, a mix and Time. It also has the option to choose via a small button (I would have preferred a switch) between the light mode or deep. Also note the possibility of feeding 9 or 12v.
The sound palette is huge, but I use it only to soften the sound. I do not think I've seen manual and frankly I do not see the point.
I just wish the button switch that always puts a doubt chosen (light / deep) mode.
Mix 1/4 the time the third and that's a pedal permanently on the PB. It allows you to make less raw sound. You can of course push settings but finds herself in a sound too typical. For small solo with a delay + Disto or clean sound I can not do without.
I was following a trade, I would have never bought it myself but it's a good surprise. I do not know either the UL mark, but this one seems very good. I do not regret this purchase.
