Designed for quick prototyping and audio projects, this PT2399 / CD2399 Reverb & Echo Effect Module provides classic analog-voiced time-based effects on a self-contained printed circuit board. Powered by the industry-standard 2399 CMOS digital delay architecture, this circuit captures the warm, organic decay characteristics favored in vintage-style delays, ambient echo boxes, and vocal reverbs.
The board features an onboard three-terminal linear voltage regulator, allowing it to run smoothly on standard single-rail DC power supplies without requiring an external 5V step-down stage. User control is integrated directly via an onboard rotary potentiometer with a knurled split shaft for immediate time/depth adjustment. Quick-connect headers provide easy routing for audio input and output, while a dedicated two-position screw terminal block ensures solid, tool-free power wiring. Four corner mounting holes allow for secure standoff installation inside stompbox enclosures, rack units, or amplifier chassis.
