I bought an mXr Microamp pedal and it works great for boosting my clean tones without having to adjust my master volume. The thing is, it doesn't seem to have any effect when my amp is set to distortion.

I have a Gibson SG Special guitar and a Line 6 Spider II amp. The distortion I use comes from the amp, not another pedal (if that matters). I'm just wondering why it seems the Microamp doesn't boost my distortion, but it works fine on the clean settings.

I'm somewhat guitar illiterate, so putting your answer in the simplest terms would be the best! :-p

probably because it just boost your gain so try turning the knob up to the max and see if you get anything. hmmm distortion from your line 6 aye then i dont know
