Patched the out into my RC50 which has the routing go to both the main output (PA) & the aux output (my marshall’s 2nd chan)
Signal to the PA was as expected… great… but with the guitar amp on, I had a horrible buzz through my guitar rig. More like a digital timing thing as opposed to electrical hum…
I suspect it’s coz I was using my normal regulated power supply to power the BB along with my pedals… but as I didn’t have the supplied PS with me I couldn’t confirm.
Just wondered if anyone else has experienced this ??
