I picked up a M13 a couple of months ago and really like it with one exception, I just can't seem to get a good overdrive and or distortion pedal sound out of it. I have just about all the POD Pro rack versions and the OD/Dist pedals sounds in them sound great. I just can't seem to tweak the right settings out of the M13. All other sounds are great. Anyone have similar issues or recommendations? Also wanted to add I have it hooked up to my amp via effects loop.
