The Boss FV-30L is a stereo volume pedal made by Boss. A volume pedal sits in your signal chain and lets you raise or lower your level with your foot, for swells, fading in a part, or cutting your signal between songs. Where a mono volume pedal controls one signal path, the FV-30L is built for two, so it fits players running a stereo rig with two amplifiers or stereo effects1.
What it does
A volume pedal is a foot rocker connected to a potentiometer: heel down and your signal is quiet or silent, toe down and it passes at full strength. The FV-30L does this for two channels at once, which is what makes it a stereo model rather than a mono one. In a buying guide on volume pedals, JHS Pedals describes where a pedal like this fits:
"BOSS carries stereo volume pedals, like the FV-30L, which are really great if you're using a stereo rig1."
Some volume pedals are built for stereo rigs. BOSS carries stereo volume pedals, like the FV-30L, which are really great if you're using a stereo rig1. The FV-30L's owner's manual is available from BOSS2.
That is the practical distinction for a player comparing pedals. If you run one amp, a mono volume pedal such as the Boss FV-30H covers the job. If you split your signal across two amps or use stereo effects like delay and reverb in stereo, a stereo pedal like the FV-30L keeps both paths under one foot control instead of leaving one channel at full volume while the other fades.
Boss publishes an owner's manual for the FV-30L on its product page, covering the pedal's setup and use2.
