Listen &ndash do you hear that? That sound coming from your amp vaguely like a swarm of African killer bees coming to chase away your audience? The Electro-Harmonix Hum Debugger Hum Eliminator Pedal completely and totally eliminates hum from any audio source. It is not a suppressor. It is not a noise gate. It is absolute silence. Small and compact so it won’t take up valuable space on your pedalboard. Green LED indicates when it’s engaged. With Box, EC.
