The Voltage Unit Meter Pedal (“VUMP”) is a guitar pedal-style level indication meter. This unit reads out signal level in the
traditional “Voltage Unit” (VU) scale, which is similar to a decibel (dB) scale, but pegged to a reference value of 0
VU=1.23VRMS. Since sound levels span many decades of pressure intensity, it is convenient to express the level in the
logarithmic dB scale. An increase of 6 dB sounds about twice as loud as the reference sound level.
The intended use for this device is to be the last “pedal” in a chain of pedals connected to an electronic instrument such
as an electric guitar or bass guitar, or microphone. It provides a convenient, local measure of your signal level just before
going to the amp or a sound board. You can also precisely equalize the volume settings of your pedals using this device.
