The Bright Onion Pedals Micro Volume Control is a small passive volume pedal: a single knob that sets the level of whatever passes through it. Because the circuit is passive, it shapes your signal without needing power, and Bright Onion describes it simply as "a passive volume control set by the knob"1. It sits in the volume family alongside rocker-style pedals like the Ernie Ball Mono Volume Pedal and the Morley M2 Passive Volume, but its knob format and tiny footprint put it closer to set-and-forget level control than to swells played with the foot.
What it does and where it goes
The knob sets the output level directly. Bright Onion suggests one use in particular: "Great from taming a loud amp by placing it in the amp's effect loop"1. In a loop, the pedal works as a fixed attenuator between the preamp and power sections, so you can run the amp's preamp hard and bring the overall level down with the knob. On a pedalboard, it works the same way as a master volume placed before or after drives, set once and left alone rather than rocked while playing.
Construction and power
The pedal is built with point to point wiring in an aluminum enclosure measuring 52x38x31mm, with Neutrik plug sockets on the input and output1. Bright Onion states that "Our products contain no batteries or lead"1, so there is no battery door and nothing to drain.
The circuit is passive and runs without power. If you do power it, the maker says to use only a 9v DC center negative 2.1mm barrel power supply1.
Price
Bright Onion Pedals lists the Micro Volume Control at £29.95 GBP on its product page as of 26 October 20261.
