Update: The parts needed for this project arrived and the pcb is populated and ready to test. The ssm2166 adapter is mounted in the socket on the right.
Prototype pcb for the SSM2166 Compressor
Also, in the package of prototype pc boards that I just received were these two items that I made for switches. The one on the right is for true bypassing with the 3PDT, while the board on the left is an adapter for a mini rotary 1P6T switch. This allows 6 capacitors to be selected by turning the knob, and I intend to use it on the input of a treble booster.


That 1p6t switch with pcb looks perfect for a vari-tone drop in for a guitar tone.
It would be good for a varitone, but I plan on using it to switch capacitors at the input of a Rangemaster-type circuit.

When do you anticipate the SSM2166 pcb to be ready for shipment? … I built your SSM2165 and it was a little too noisy but seemed very promising. I’m hoping this would be an improvement over the 2165.
Thx!
