The SP-25L-PRO's rear cutaway and extended curved surface are ergonomically crafted for comfort in both standing and sitting positions. It features dual 25K outputs with polarity selection and a latching toe switch, ensuring compatibility with a wide range of devices for guitars, keyboards, and acoustic instruments, suitable for both live performances and studio sessions.

Engaging the toe switch activates an ultra-bright sapphire LED and an acrylic base, producing a halo effect around the pedal that is visible from nearly any angle. Additionally, when paired with compatible MIDI controllers and digital devices, the illuminated base serves as an indicator for the status of remote effects.

Two expression outputs with independent polarity switches for each channel. This allows for compatibility with a wide range of different devices.

A third output connects the latching toe switch to compatible MIDI controllers and and digital effects allowing effects such as wah and pitch to be turned on and off from the expression pedal.
