This compact pedal packs a 5-band EQ and an Ashdown-exclusive Shape switch, enabling you to sculpt your sound with precision. Inspired by the legendary MAG, ABM, and Rootmaster amplifiers, the Pro-DI delivers a rich, valve-like warmth that transforms your bass lines into sonic masterpieces.

Whether you're on stage or in the studio, the Pro-DI’s analog circuitry ensures your bass remains at the forefront with authentic tube-simulated tones.

Setup and maintenance

Critic Reviews

Ashdown Announce Pro Di Pedal - Bass Guitar Review

bassguitarreview.co.uk

While the Ashdown Pro-DI Bass Preamp Pedal presents a robust feature set ideal for touring bassists—complete with a 5-band EQ and valve emulation—it ultimately falls short in user experience. The pedal is marketed as durable and repairable, but its high draw and lack of a power supply may deter some musicians. Additionally, features like the headphone output and line mix control are commendable, yet they can't quite compensate for the apparent complexity in setup. In a crowded market, the Pro-DI may struggle to stand out.

The Ashdown Pro-DI Bass Preamp Pedal delivers a robust feature set ideal for touring bassists, including a reliable transformer-isolated DI output and a comprehensive 5-band EQ. Its valve emulated overdrive is a standout, allowing for smooth gain adjustment without compromising volume. However, some users might find the pedal’s hefty design a bit cumbersome for travel. Overall, it’s a solid choice for bass players looking to simplify their setup without sacrificing quality, though it comes with a weightier footprint than some competitors.
