Description
Step into the world of vintage tone with the Universal Audio Woodrow ’55 Instrument Amplifier. This pedal is a sonic tribute to the legendary '50s tweed amps that shaped the sound of rock 'n' roll. Designed for musicians who crave the warmth and depth of tube-style breakup, the Woodrow ’55 offers an authentic emulation of the iconic 1 x 12-inch combo amplifier. Powered by dual-engine processing, it delivers a dynamic range of sounds from pristine cleans to gritty overdrive.
With three distinct boost types, you can seamlessly transition from a classic '50s growl to modern, articulate tones. The UAFX app compatibility offers further customization, allowing you to access artist presets and tailor your sound for any stage or studio performance.
The Woodrow '55 is equipped with advanced mic, cab, and speaker modeling, bringing the atmosphere of a live room to your pedalboard. Its "4-cable" mode bypasses your amplifier's preamp, adding two extra channels and enabling you to explore an expansive tonal palette. Whether you’re going direct to front-of-house or recording in your DAW, this pedal packs the tried-and-true sounds of a vintage tweed into a compact and powerful unit.
