Universal Audio Woodrow '55 Pedal

Unlock Classic '50s Tweed Tube Tones with the Universal Audio Woodrow '55 Pedal

If you're on the hunt for that iconic '50s tweed amplifier sound, the Universal Audio Woodrow '55 Instrument Amplifier Pedal is your ticket to sonic paradise. This pedal encapsulates the warmth and breakup tones of the legendary '50s 1 x 12-inch combo amplifiers, delivering authentic tube-style tones that defined the rock 'n' roll overdrive sound for decades. With three distinct boost types, Bluetooth compatibility, and the ability to bypass your amplifier's preamp for added versatility, the Woodrow '55 is your key to achieving classic tube tones in a compact pedal format.

Three Boosts, Three Eras of Tone

The Woodrow '55 offers three distinct boost modes that cater to different tonal preferences. In Stock mode, you get pure clean gain with enhanced midrange and treble response. The KP-3K mode provides clarity and high-end detail inspired by an '80s digital delay pedal's preamp design. For those seeking thick, saturated, and warm tones, the EP-III mode based on a tape echo of the same name delivers plenty of gain and vintage character.

Sonic Experimentation with Cab/Mic/Speaker Emulations

Part of the Woodrow '55's magic lies in its accurate speaker/cab emulations, powered by Universal Audio's Dynamic Room Modeling technology. This pedal comes with three cab/mic/speaker settings perfectly matched to the amplifier modes. You can further expand your tonal palette by registering the Woodrow '55, which grants you access to three additional cab sims. Experimenting with different speaker and amp pairings has never been more exciting.

Enhanced Control and Connectivity

The Woodrow '55 boasts a "4-cable" mode via the UAFX Control app, allowing you to bypass your amp's preamp when the pedal is engaged. This feature adds two extra channels to your amplifier, enabling seamless channel switching and a more realistic tube-style experience. The pedal's Bluetooth compatibility enhances your control options, allowing you to connect to Universal Audio's UAFX app. This app provides extensive editing capabilities, access to artist presets, custom presets, and more.
