Here is my 2nd entry; the Deluxe Tremolo.
The idea of this pedal started when I read about the Cardinal Tremolo by Midwayfair. I had never heard of harmonic tremolo before, but it got my interest straight away.
After reading about what harmonic tremolo was and listening to a few examples on YouTube I decided I wanted to try and build one.
I took the non-scientific approach and connected my old standard trem to the breadboard and started playing with different value capacitors and resistors between the preamp- and output stage.
It didn't really sound like a harmonic tremolo so I ditched that idea, however the sounds I did get where interesting enough to keep the project going anyway.
Considering the low parts count of this addition to the standard tremolo I thought it might be possible fitting it inside the existing small 1590BB enclosure.
I decided on having only one additional knob for the extra preset sounds along the standard trem sound, instead of having too many knobs to tweak.
The old tremolo I designed using the building blocks of the uni-vibe, and with the capacitor back in place between the collector of Q3 and the base of Q4 it is now sort of a 1-stage uni-vibe/tremolo.
