A multi-effects unit that's as easy as a stompbox - that's the beauty of the new ME-70. The friendly, knob-laden design makes tone creation a snap, but with a powerful COSM AMP section derived from the GT-10, the ME-70 takes the "EZ effects" concept to new heights.

1. Make sure that you have the correct power supply plugged in.
2. If you are using the BOSS power supply, it could be defective. Measure the voltage it is producing and make sure it is correct.
3. If the voltage is correct, then the problem is inside the unit, and it will need servicing.

BOSS ME70 Factory Reset.
Just do this:

Is distortion changes like we turn the OD/DS selector (changes to Boost-Natural-OD1-Blues etc)?
If so, the OD/DS potentiometer need to replace.

If the changes are like increasing/decreasing GAIN/BASS/MID/TREBLE/LEVEL and also TYPE of pre-amp, then one of PREAMP potentiometer is bad.
