The 3Verb is a very analog sounding reverb pedal, although it is bases on the digital BTDR-3 module. Controls for Decay and Mix enable to get sounds from room-size to a big cathedral reverb.
Most of the electronics is integrated in the compact reverb module, so the parts count is quite low. This makes this project also suitable for beginners. The BTDR-3 module is placed on the bottom pcb side and soldered on the top side!
Trim pot P1 sets the output volume of the reverb. It should be set to unity with the bypass signal. Of course you can also set it a little louder to boost the reverb a little.
