Used 2020s Mad Professor THE GREEN WONDER Effect Pedal

Used Mad Professor The Green Wonder overdrive pedal from the 2020s in great condition, delivering smooth, amp-like drive with a clear midrange boost—perfect for blues, rock, and pushing a tube amp. Simple, player-friendly controls include Volume, Drive, and Tone for quick dial-ins from gritty edge-of-breakup to saturated lead tones. Built in a compact, rugged enclosure and designed for standard pedalboard power (typically 9V DC, center-negative) with instrument in/out.
