The Warm Audio WA-WD Warmdrive is a true reproduction of a highly revered pedal known for delivering the tones of an unattainably overdriven amp. The original pedal is known to go from silky-smooth tones reminiscent of a special overdriven amp at the sweet spot, all the way to sustain-rich distortion.The WA-WD Warmdrive pedal combines true-to-original components and circuit design to achieve the same tone and sonic profile of the legendary original pedal. Just like the original, the “secret sauce” of the Warmdrive is the unique voice/tone control combination on the stompbox, giving artists extra versatility. This control allows the player to modify the frequency both before (Voice control) and after (Tone control) the clipping stages.
