So i fired up my rp350 last night, and when I hook it up to an amp or plug in some headphones, I get no output. The machine powers on and seems to start up fine, and If i turn on the drums on it i can hear them playing, but they sound faint and distant. No matter what i seem to do, i can't get any guitar related sound to come out. anyone have any idea what might be wrong?
have you done a reboot?
check all your connections...make sure you don't have a cable loose somewhere. Maybe try different cables too...
Don't forget to check the master volume instead of just the channel volume!
