The legendary American tweed tube amp sound that shaped decades of iconic recordings from Chuck Berry to Neil Young is now at your fingertips with the UAFX Woodrow '55 Instrument Amplifier pedal. This powerhouse effects pedal harnesses UAD's renowned modelling expertise and dual-engine processing to deliver the sweet cleans, rich overdrive, and grungy distortion that made tweed amps a studio staple for artists and producers worldwide.
Built to replace traditional amp rigs, the Woodrow '55 excels both on stage when running direct to front-of-house and in the studio for DAW recording. You'll get the inspiring, album-ready tones of an expertly miked "golden unit" vintage tweed amp within seconds, complete with authentic tube growl that captures the essence of these coveted amplifiers.
Push your tweed tones into new territory with classic British speaker swaps and boosts, including preamps from the iconic KORG SDD-3000 rack unit and Maestro EP-3 tape delay — all accessible at the flip of a switch. The included UAFX Control mobile app expands your sonic palette further, allowing you to download custom artist tones, manage your presets, and explore the rich history of the tweed amp that started it all.
