Output Level knob not working.
« on: Time Format »

Hi there,

I bought my first ADA MP-1 today. Exciting moment hooking it up!
I connected to a Fender combo amp (haven't got a poweramp yet) and tried both the input jack and the FX return jack on the amp, like it says in the manual.

The unit is of course second hand and well roadworn, but everything seems to work - except ONE thing:

The output level knob on the front doesn't work like it should.
When connecting from output A there is only a faint signal and the level knob doesn't change it at all.
When connecting from output B there is no signal until I turn the level knob all the way up but then the sound come blasting.

So... Is it possible to fix the level knob? Is it analog?
Is the difference in output level between A and B part of this problem?


Hope someone can help me :-)


Regards,
Martin

You can try spraying contact cleaner in the pot.  Marshalljmp has these knobs available at a good price.
