Catalinbread · pedal
The Catalinbread CATDLSR is a version of the Portland boutique builder's Dirty Little Secret Marshall-voiced foundation overdrive circuit. The DLS models the tone and response of a cranked British Marshall amplifier, delivering classic rock overdrive with dynamic, amp-like feel. Controls include drive, volume, and a three-band tone stack based on Marshall amplifier EQ alongside a mode switch for Super Lead and Super Bass voicings. Used by blues and classic rock players seeking authentic British overdrive character from a compact pedal.
