Expression

Expression pedals allow real-time control over specific parameters on compatible guitar pedals, such as volume, delay time, modulation depth, or filter sweep. Used with an expression input, they let players shape effects dynamically with their foot, adding movement and performance control that cannot be achieved with fixed knob settings.

MIDI

MIDI pedals use the Musical Instrument Digital Interface standard to communicate with other guitar pedals, effects units, and hardware. They allow control over presets, parameters, and switching across multiple devices from a single controller. MIDI integration makes it possible to build complex, synchronised pedal setups while keeping control simple and consistent.

New

This is brand new, fresh in, and a UK warranty is included. New Gear always comes from trusted UK music retailers.

Vibrato

Vibrato refers to a guitar pedal effect that modulates pitch slightly up and down, creating movement and a sense of wobble in the sound. Unlike tremolo, which changes volume, vibrato affects pitch only, producing anything from subtle shimmer to pronounced, warbling textures. It is often used to add character, depth, and vintage-style modulation to guitar tones.

Wah

Wah refers to an expressive filter effect that sweeps through a range of frequencies, creating a vocal-like “wah” sound. Controlled in real time with a foot-operated treadle, it allows players to emphasise different parts of the frequency spectrum as they play. Wah pedals are commonly used for lead guitar, funk rhythm work, and expressive solos, responding closely to picking dynamics and foot movement.
