Well my first band rehearsal with my new Line6 M13 didn't go too great last night. I had some serious noise problems that wouldn't go away. It started off fine, my bass player was late so we started with out him. I plugged my guitar into my Digitech EX7, then into the mono input of the M13, then the mono output of the M13 into channel 1 on my Fender Hot Rod Deluxe, Both the M13 and EX7 were powered using their own power supply. So everything was fine and I was diggin the tones I was getting from the M13.
About an hour in the bass player arrived and setup his Line6 Low Down amp, we started playing and all was well. About 2 songs later a really loud crackling noise came through my amp, similar to the kind of noise you get with a bad lead or input jack. I set about eliminating the issue, I went from guitar direct to amp - no noise. So went with guitar and M13 into amp, again no noise, next guitar EX7 and amp - no noise.
Went back to original config Guitar - EX7 - M13 - Amp and got crackling noise again so at this stage I suspected the patch lead between the EX7 and M13 so replaced this with a known good lead but still had crackling. I eventually gave up and used my old stomp box board instead of the M13 and all was fine.
I can only assume that this was some sort of electrically induced interference, the bass player thinks he heard a slight crackling interference on his bass amp too but it was plugged into a completely seperate power socket. We were practicing in the same room that we've always practiced in and when I stopped using the M13 the rest of the rehearsal went fine. I really don't want to have to send back the M13 but if it's that sensitive to interference then I don't think I could possibly use it live.
anyone else experienced similar issues or have any tips on how I might isolate the issue. One thing that I could try is on the M13 you can switch between true bypass and DSP bypass, I'm not quite sure what the difference is between the two but I've seen some posts on the line6 forum that switching this setting can help eliminate noise.
Oh by the way I know very little about electronics and grounding etc. as you can probably tell.
