VP-1 Volume & Expression Pedal — Fully Passive, No Power Needed

One compact treadle that works either as a volume pedal or as an expression controller, depending which jack you use. It's entirely passive — no battery, no adapter, nothing to fail mid-set — and small enough to sit on a crowded board where a full-size volume pedal wouldn't.

Highlights

• Two jobs in one pedal — volume control or expression controller
• Fully passive: no power supply, no battery, one less thing to go wrong
• Compact footprint compared to a standard volume pedal
• Anti-slip textured treadle and non-slip rubber base pads
• Smooth, progressive sweep for swells and filter control
