The GUPtech PdeQ is a professional presence and depth guitar EQ pedal designed to emulate an amplifier’s missing presence and resonance/depth controls. It enhances high-frequency sparkle and low-end depth to help solid-state amps or rigs lacking tone controls feel more dynamic and amp-like. The pedal features independent presence and depth controls with on/off toggles, offers true bypass switching, and can act as a clean buffer when controls are off, adding clarity and body to your tone. Handmade in Québec, Canada and suited for high-gain and metal applications as well as general tone shaping.
