Howdy!
I have the Synth 9 on my pedalboard, and basicly everytime I turn the power supplies on and go to use it the Synth 9 I have to unplug the power lead, replug it, turn the pedal on then spin one of the knobs back and forth, then it suddenly kicks in and then it’s good. I dunno why but I always have to do this then it works great. Seems to be a weird thing with the pedal.

I thought I’d share this incase it helps someone
