Hello,

I meet a problem with my new Ring Thing & Expression Pedal…

So, now if I plug a M-Audio EXP expression pedal, or any other E-Pedal I tried like BOSS EV5,
The toe down position is always a little bit lower current setting of the COARSE knob…
And if I unplug the pedal, the good tune/setting comes back..

I tried to turn the pot on the expression pedals, to try different setting with different models…
But it always do the sames….

Could you help me to find a reason of this…

Thank you very much !

John.
