Astonishing, Sturdy build!
Here is how it works:
first decide which direction you want to go, up or down, this can be done by the range switch.
When you decide your direction adjust the pitch knob to get your desired pitch , I play metal, for soloing purposes i found the range of pitches enough for me.
Then as you desire, you can adjust the ballistics, the shift knob to decide the rate of the incoming to be pitch shifted, the return knob to set the rate of incoming note to return to its normal place.
I found the momentary knob helpful, if i want to bypass the pedal I can just turn it off, and trigger the pedal when i press on footswitch.
it took me 10 minutes to figure out this pedal, so no complication.
totally recommended if you want to have whammy effect without having floating bridge.
the only thing i wished for is the range to has footswitch instead of regular switch, if you want to change the direction you have switch it by your hand, hard to do by foot.
Important: this pedal doesn't support battery, so make sure to have your 9V adapter.
