The Universal Audio UAFX Woodrow '55 instrument amplifier effects pedal is an innovative pedal that perfectly captures the warm, tube-driven tones of the iconic tweed amplifiers of the 1950s. Featuring cutting-edge modeling technology and components, the Woodrow '55 provides an end-to-end emulation of a coveted 1x12" combo amp from rock 'n' roll's golden age.

Authentic Vintage Tone and Breakup

The Woodrow '55 delivers the sweet cleans and saturated overdrive of a meticulously miked vintage tweed amp. With three distinct boost options, guitarists can push the pedal into a throaty growl reminiscent of early rock records. The "Stock" boost provides clean gain, the "KP-3K" boost emphasizes clarity and high end, and the "EP-III" boost generates a thick, warm tone.

Studio-Quality Speaker and Microphone Emulations

A major component of the Woodrow '55's hyper-realistic sound is its emulation of vintage speakers and microphones. The pedal comes with three cab/mic/speaker settings optimized for the three boost types. Upon registration, three additional cab options become available as free downloads. These studio-quality emulations provide an array of tones suited for any genre or recording situation.

Advanced Connectivity and Control

The Woodrow '55 features a USB-C port for firmware updates and Bluetooth connectivity to pair with Universal Audio's UAFX app. The app unlocks enhanced editing features, access to artist presets, and more. For even greater control, the Woodrow '55 has a "4-cable" mode that bypasses an amplifier's preamp, effectively adding two extra channels. Multiple UAFX pedals can be daisy-chained in this configuration.

Road-Ready and Built to Last

Despite its advanced technology and components, the Woodrow '55 has a streamlined, roadworthy design. Its durable metal chassis and footswitches are built to withstand years of performance and studio use. For grab-and-go portability, Universal Audio includes a recycled nylon gig bag to protect this professional-grade pedal.
