Used Walrus Audio FUNDAMENTAL TREMOLO Effect Pedal

Used Walrus Audio Fundamental Tremolo in good condition delivers rich, musical pulse from subtle shimmer to deep chop. Simple controls make dialing in speed and depth fast, while multiple wave shapes let you choose smooth sine-like movement or sharp square-style stutter. Designed for standard 9V DC, center-negative power and a pedalboard-friendly enclosure, it adds movement and character to clean or driven tones without getting in the way.
