Custom built fOXX Tone Machine
Here’s a custom built fOXX Tone Machine from zeta sound, dressed in velvet.
Used the same circuit board layout as in this build. Hosted in a Hammond 1590BB enclosure.

Work in progress
Some images from the workbench.
Mounting hardware in a Lady Dirt tube pedal.
The circuit board of the Bull pedal. There’s silicone diodes clipping and in the front of the image you ses two germanium AA144 diodes. There’s three BC184 transistors and one 2N3904. Posted earlier here.
Just had to take this picture. A cap from the 1950:s vs a modern one, same uF and voltage rating.
Here’s a gut shot from the new prototype of the Maestro PS-1A clone.

Yamaha CH-01 Chorus repair
A chorus from the -80:s, the Yamaha CH-01. Based on the MN3009 256 stage BBD chip and the MN3101 clock generator.
Had the circuit recaped and trimmers adjusted for bias, clock speed and depth.
And here we have a chorus once again delivering.

Maestro PS-1A V2
Video and pictures of the V2 zeta-sound clone of the Maestro PS-1A phase shifter.
Mainly changes made in the main circuit board layout , allowing the stompswitches a bit more centered and using onboard in/output jacks. The speed selector circuit works the same as in V1, tap the switch and change the speed through three presets. Blue -> Slow, Green -> Medium, Red -> Fast.
