I'm trying to get it to play on my electric guitar. The device works because the screen turns on and it works through headphones however whenever I try and plug it into my amp the effects won't play, my guitar just sounds as it always does. It's definitely connected properly though because the tuner on it works. Any ideas on why this is happening?
There must be a master volume setting on it that's turned down. You haven't left the headphones plugged in while you're using it with the amp have you? The headphone socket will mute the output, probably
