Detail 01
Mono signal path
One in, one out. A stereo rig running two amps or a stereo delay needs the stereo version instead.

BOSSFV-500H Mono Volume Pedal

Independent shopping perspective
The Korena take
Mono volume pedal built on the larger FV-500 chassis. For players who want swells, volume rides, or an expression-style sweep in a pedal that survives touring.
Strong match
Who this is for
- Volume swells for ambient and atmospheric parts
- Riding levels between rhythm and lead without touching the amp
- Controlling wet effect level when placed after delay or reverb
Consider the trade-offs
When to look elsewhere
- Stereo rigs — this passes one channel only
- Small boards, since the chassis footprint is large
- Players wanting boost; it attenuates, it does not add gain
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
High-impedance design
Meant for the front of the chain, before buffers or preamps. In the wrong spot, treble loss and volume taper get uneven.
Detail 03
Treadle-operated sweep
Foot control means both hands stay on the instrument, which is what makes real-time swells possible.
Detail 04
Minimum volume control
Sets the floor at heel-down. Set above zero and you keep a quiet signal instead of full silence at the bottom of the sweep.
Detail 05
Full-size FV-500 chassis
Much bigger than a BOSS compact. Measure your board before buying — it will not slot into a compact-sized gap.
Final check
Know before you order
- 01Position matters: high-impedance means place it before buffered pedals, not after
- 02Chain placement changes the result — before drive controls gain, after it controls level
- 03Instrument cables are not included
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What's the difference between this and the low-impedance version?
The H is high-impedance, meant for passive instrument signal at the front of the chain. The low-impedance version belongs after buffers or in a line-level loop.
02Can I use it as an expression pedal?
It is built as a volume pedal with a mono audio path. An expression pedal sends a control voltage to another device instead, which is a different job.
03Why does my tone get dark when I roll it back?
That is usually impedance mismatch — a high-impedance pedal placed after buffered gear, or the reverse. Move it to the front of your chain and check again.
04Will it work with an active bass or keyboard?
Active outputs are low impedance, which is not what this version is designed around. The low-impedance FV-500L is the match for active instruments and line-level sources.
