I just got home and turned on my amp and I am getting no signal from my guitar. SO I plugged direct into the amp no effects and it worked fine. I narrowed it down to the M13 as all cables and pedals are working perfectly, no crackles in cables, no loose inputs, etc. SO I played around with the settings on the M13, did a factory reset, all to no avail. Then when I swapped it over to true bypass and turned off all the effects I got signal. Basically as long as the looper, tuner, DSP bypass, Distortion, Reverb, Delay, Filters are all off it works great. Rendering it useless. I have tried reseting it several times and no luck.

Has this problem happened before. Any suggestions on methods of attempting to fix this?

If I do a warranty exchange how long does it take to get a new one back. (I have a show in two weeks.)
