Hi everyone, I've had a few intermittent issues where my band rehearses, and I'm wondering if it's a power issue? A few times my expression pedal would stop working. After restarting the unit, it worked fine. Also, when using the unit to channel switch my DSL40c, it would suddenly stop changing the channels, even though the red/green indicator light on the amp would change. I haven't had this issue at other places, but I also use my rig mostly at this rehearsal space. I've read some things that mention odd issues when the HX Effects doesn't have clean power. Just wondering if that could be the cause?
