The 3Verb

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.

The 45er – Phaser

The 45er is the smaller brother of the 90 (Der Phaser). Featuring only 2 instead 4 phase stages, he delivers a nice subtle sound and fits well into your basic sound.

The trimm-pot for biasing the FETs can be simply dialed in by ear. If it sounds good for you, it is right :-)

Here the files to build the Phaser:

Der 45er Phaser

Der Phaser

The Phaser is based on the phasing classic, the Phase90. It is enhanced by a depth-pot. For troubleshooting issues you can also find a list with measurement values below.

To get the “R28-Mod”, in the Phaser schematic that´s the R15. If you remove that, the sound gets moire balanced and smoother.
