Have you ever wanted more control over your effects? Already got some effects with expression inputs but not taken advantage of it yet? Then this may be the one pedal that never leaves your board. The universal Mission Engineering SP-25M Pro expression pedal features a wide range taper and a momentary toe switch that run off of separate outputs so you can control your rig however you want.

Here’s what Mission Engineering say about the SP-25M PRO

The SP-25M-PRO features the new Mission Aero design like the EP-25-PRO, and adds an integrated momentary toe switch. This works with compatible modelers, digital effects, and MIDI controllers allowing effects to be turned on and off on right at the pedal. At just 1.7lbs, the all aluminum Aero is half the weight of a standard Mission pedal, ideal for fly rigs and other weight sensitive applications. The 25K Ohm linear taper potentiometer is fully sealed for a smooth action and a long life. Dual channel outputs control one or two devices simultaneously, and can be expanded with Expressionator to control up to four devices from one expression pedal.

The extended sweep of the Aero design makes this an ideal all round expression pedal for volume control as well as, wah, whammy, and 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-25M-PRO is perfect not just for for guitar, but keyboards, acoustic instruments, and both live and studio use.

The SP-25M-PRO features independent polarity switches for each channel. This allows for compatibility with a wide range of different pedals, rack effects, modeling amplifiers, keyboards, MIDI controllers and other expression controlled devices. The integrated soft touch momentary switch works with most current digital processors and MIDI controllers that support an external switch.

The SP-25M-PRO is finished in a choice of resilient, non reflective black stealth style powder coat, or a dramatic gold carbon fiber graphic finish.

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.

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.
