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.
How about a clone of a fOXX Tone Machine. First prototype from zeta-sound, including germanium diodes, stompswitch for octave and bypass, DC-Jack and battery space. Hosted in a 1590B type of enclosure.
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.
