I have a DigiTech BP355. I'm having a problem and wanted to see if anyone else has encountered the same. There is no on/off switch so I have been leaving the unit on pretty much all the time. This morning when I went to practice, there was no sound from the DigiTech. I unplugged from the pedalboard and plugged directly into the amp. Everything was working fine without the pedalboard. Plugged back in and, nothing. Anyone had a similar experience with the DigiTech BP355?
