Description
Not every volume pedal is built for a mono guitar rig, and the FV-50L makes that clear from the jump. This is a low-impedance stereo unit designed to sit directly in the signal path of stereo keyboards and stereo effects units, handling both channels with the smooth, mechanical feel Boss volume pedals are known for.
- Two inputs and two outputs cover full stereo operation without splitting signal externally
- A Minimum Volume knob lets you set a floor for the pedal’s sweep, so heel-down never means total silence — handy for keeping a bed of sound present or avoiding dead air between swells
- A dedicated Tuner Out jack keeps a tuner connected at all times, so rolling the pedal back gives you a quick, quiet way to check pitch mid-set without unplugging anything
On a pedalboard, the FV-50L works best positioned wherever stereo signal actually exists in your chain — after stereo modulation or ambient effects, or straight off a stereo keyboard rig — since its low-impedance design is built to handle those signals directly rather than as a passive guitar-level volume control.
- Width: 86 mm / 3-7/16 in
- Depth: 200 mm / 7-7/8 in
- Height: 54 mm / 2-1/8 in
- Weight: 400 g / 0 lbs 15 oz
Simple in concept, but purpose-built: a volume pedal for players and keyboardists working in stereo, with the small conveniences — minimum volume floor, tuner access — that keep a live rig running smoothly.
