UADx Woodrow ’55 Instrument Amplifier

The deal

$29 at KVR Marketplace (down from $99). Sale ends May 25, 2026.

What it is

The UADx Woodrow '55 is a circuit-modeled simulation of a 1950s tweed guitar amplifier. Universal Audio built it from a full analysis of the original circuit - preamp, power tubes, tone stack, and output transformer - to reproduce the punchy cleans and tube-driven overdrive that made that amp famous. It ships with selectable mic and cabinet pairings so you can shape the recorded tone without touching a physical cab.

Who it's for

Guitar-playing producers and engineers who track electric guitar in a DAW and want a realistic vintage American amp sound without needing a physical amp, a mic, or an isolation room.
