I bought my M13 back in April 2010 and I love it - absolutely my favorite pedal. I've had two issues with it:

Big issue: On Sunday afternoon, I plugged the M13 in at church only to find that the mono inputs now produce a loud angry hissing noise, and virtually nothing else. I just bought it in April! Any thoughts? (Stereo inputs work, but still make a lot of noise.)

Smaller issue: The model-select knob that you press to select between stompboxes on the left-most column will no longer depress. In other words, I can turn it, but it is permanently stuck on the DL-4 delay stompbox feature. I can't access anything else.

Any thoughts anyone?

Thank you!
