Ditto mike looper problem


Hello everyone..

Im in desperate need of help.. i have the ditto mike looper which has a fault.

The pedal itself works fine if the switches on the box itself are used by foot/ hand... when i use my mp75 mic it will not operate the looper at all.  It is ( not )  the mic or the lead as i have plugged them into my friends identical ditto looper and they work fine..  i have also done the sequences of pressing the switches when powering up or in the other reverse way but still nothing..

If anyone can help i will be very  grearfull.

Thanks ..
