Get Hot-Rodded Sounds

Take your rowdy tweed tones further using tried-and-true British speaker swaps and boosts — including preamps from the iconic KORG SDD-3000 rack unit and Maestro EP-3 tape delay — at the flip of a switch***. Only Woodrow '55 puts authentic tube growl and hot‑rod mods under your chucks, docs, or crocs.

Expand your Sounds with MIDI
