You’re on stage in between songs. You just changed your pedal settings and the next song is about to start. How are your levels? Too high? Too low? Maybe you’re not sure until the song starts and you hear yourself. Well, if you just had the Mini-VUMP (Voltage-Unit Meter Pedal), you could hit the Mute switch, strum your guitar, check your levels, and discover you left the Boost pedal on before you embarrass yourself on the next song! You can also use this device to equalize the loudness of your pedals on your pedalboard! Just turn one pedal on and off and change your gain settings one pedal at a time.
