Yesterday Effects Defiant Jazz FX Pedal

U.K First

The Yesterday Effects Defiant Jazz is a faithful recreation of one of the most celebrated solid-state clean tones ever produced. Inspired by the legendary Roland Jazz Chorus 120 preamp topology, Defiant Jazz captures that unmistakable crystalline clarity in a compact, pedalboard friendly format.

Rather than chasing tube emulation, the original Jazz Chorus built its reputation on pristine headroom, fast response and shimmering articulation. That bold solid-state voice became a fixture on countless classic recordings and touring rigs, and Defiant Jazz brings that legacy clean tone into a package that weighs 60 pounds less.

This is a value-for-value, component-for-component recreation of the clean channel (without the bright switch), designed to preserve the clarity, punch and glassy character players rely on.

Internally, a charge pump steps a standard 9V center-negative supply up to 36V, mirroring the original circuit’s operating voltage. The increased headroom ensures clarity, dynamic response and that unmistakable hi-fi clean feel. Because the circuit quadruples input voltage internally, it is essential to power the pedal with 9V only.

For players chasing pristine cleans, articulate pedal platforms or that unmistakable shimmering solid-state voice, Defiant Jazz delivers the legacy tone, without the back pain.
