    Hey guys just picked up this awesome effect unit!


    Does anybody out there have a manual they could or pdf theyd be willing share? I think there might be a few problems with my unit though and I'd like to give the manual a once over just to make sure I'm not just being an idiot.

    Thanks for any and all help guys!

    Well the pot that controls the effect mode is supposed to be able switch through the 6 waveforms as well by pushing in the knob like a shift key function. Well the shift doesn't work on it and I'm stuck on the last waveform it the pedal was set to. It's a weird type of pot I'm not familiar with plus everything including pots is mounted to the circuit board. Master bypass is also shot so the pedal is just always on too. Again, weird switch mounted to its Own separate mini board. The guy on eBay said everything worked fine, obviously he didn't try it out before selling it because I noticed these problems within minutes after unboxing it and plugging it in. Currently awaiting a response to see if I can get something of a refund. I'd still like to keep this if it can be fixed, I can't tell it can make some amazing sounds with what I'm able to do with it as is. Truly a marvel of what this evelope filter is capable of!
