The all aluminum switching expression pedal with illuminated base

The extended sweep of the Aero design makes this a great all round expression pedal for volume as well as effects parameter controls. The rear cut away and extended length curved surface are ergonomically designed for comfortable use in either standing or sitting positions.

The SP-25L-PRO has dual 25K outputs with polarity selection and a latching toe switch, compatible with many devices for guitar, keyboards, acoustic instruments both live and in the studio.

Activating the toe switch lights an ultra-bright sapphire LED and acrylic base that creates an illuminated halo effect around the pedal visible from almost any position. When used with compatible MIDI controllers and digital devices, the illuminated base can indicate the status of a remote effect.

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.

Volume

Volume pedals control the output level of a guitar signal using a foot-operated treadle. They allow smooth volume swells, dynamic control during playing, and easy muting between songs. Volume pedals can be placed at different points in the signal chain to either control overall loudness or adjust gain and drive behaviour when positioned before distortion or overdrive pedals.
