Centavo Mod

The Warm Audio Centavo Mod is a compact overdrive and boost pedal using the same circuit and components as the original Centavo. Its Gain control ranges from clean boost and edge-of-breakup sounds to more saturated overdrive, while Treble adjusts the high-frequency response and Output controls overall level. A rear-mounted MOD switch extends the bass response for increased low-end weight. The circuit uses TL072 op-amps, vintage-style diodes, carbon and metal-film resistors, and a charge-pump voltage regulator for high-headroom operation. It features buffered bypass and top-mounted 1/4-inch input and output jacks.
