4-in-1 Volume, Wah & Expression Guitar Effects Pedal

4-in-1 Control for Volume, Wah and Expression

Take precise command of your tone with a compact pedal that combines four essential functions in one unit: Volume, Wah, Volume/Wah and Expression. Designed for guitarists and bassists who need reliable, repeatable control on stage and in the studio, this analog pedal streamlines your board while keeping your signal clear and responsive.

The pedal's analog circuit is built for smooth, natural response, with an active/passive design that works comfortably with a wide range of instruments and pickup types. Choose between dedicated Volume, expressive Wah, combined Volume/Wah, or Expression mode to control external effects. A visible pedal position status indicator shows your treadle position in real time, so you always know exactly where your volume or wah sweep sits in the mix. A Wah Range selector lets you switch between WARM (approximately 290 Hz-1.4 kHz) and CLASSIC (approximately 360 Hz-1.8 kHz) for different tonal focuses, from rounded, vocal mids to sharper, cutting wah textures.

The unit features a 1/4" mono audio input and output, runs on a standard 9V DC center-negative power supply, and draws a maximum of 30 mA-ideal for modern pedalboards. With an input impedance of 1 MΩ and output impedance of 100 Ω, it is designed to integrate cleanly into most signal chains. The compact footprint (approximately 81 mm W x 162 mm D x 51 mm H) saves space while still providing a comfortable treadle area and textured, slip-resistant surface. The housing combines lightweight metal construction with a reinforced shaft connection for dependable use under frequent footwork. Package includes the pedal and a user manual for quick setup and configuration.

Why It's a Smart Choice

• Four core functions (Volume, Wah, Volume/Wah, Expression) in one pedal, reducing the need for multiple separate units.
• Analog circuit with active/passive operation for consistent, musical response across a wide range of instruments and setups.
• Real-time pedal position and status indicators for precise control during live performance and recording.

FAQ

Q: Can this pedal be used as a standard volume pedal in front of my amp?
A: Yes. In Volume mode it works as a straightforward volume pedal, designed to sit comfortably in front of an amp or in an effects loop, depending on your preferred routing.

Q: How does the Volume/Wah mode work?
A: In Volume/Wah mode, the treadle can be configured to provide both volume and wah control, allowing you to transition between swells and filter-style effects without switching pedals.

Q: Will it work as an expression pedal with other effects units?
A: Yes. In Expression mode, the pedal can control compatible external effects or multi-effects processors via the expression connection, letting you adjust parameters such as filter cutoff, modulation depth or delay time in real time.

Q: What power supply do I need?
A: The pedal requires a 9V DC center-negative power supply with at least 30 mA of available current, which is standard for most pedalboard power systems.
