The 3Verb is a guitar effects pedal that provides a analog-sounding reverb effect. It is built around the digital BTDR-3 module. The pedal features two controls: Decay and Mix. These controls allow the user to adjust the decay time and the mix level of the reverb effect. The reverb effect can range from a small room-size reverb to a larger cathedral-like reverb. The electronics of the pedal are mostly integrated into the compact reverb module, resulting in a low parts count. This makes the project suitable for beginners. The BTDR-3 module is placed on the bottom side of the PCB and soldered on the top side.
