Hello! I have a bassics bpa-1 which I love….has a prob. I was using a zoom b1xon i plugged into the effects loop of the bassics preamp. Sounds ok and no prob. Then the preamp shut down. Checked the cable …..the off on switch…..everything looks still ok. No burning smell. Wondering if the zoom inthe effects loop fried the pedal some how . Also checked the fuse…..looks ok. Any suggestions? Thanks
