[1383] SSM2166 Compressor v2

SSM2166 compressor

At last! After a pcb layout error, and then the maker of the prototype pcbs dropping the ball on the revised boards, I have finally got the updated SSM2166 compressor soldered together and working.

You may remember the SSM2166 as the chip used in the Q&D Compressor 2, that I published years ago. It has been out of production in the DIP package for a number of years, but Small Bear Electronics has bought some of the surface mount version and had them soldered to a DIP conversion board. This makes the SSM2166 available once again for the average home builder.

I will have pc boards available for this project before the end of this month. Stay tuned!

And where do I find the order form. It’s really close to the end of the month. I just bought a PYLE PPDLCS. I’m still interesting in doing the DIY.

The pc boards have been ordered and should be here in about 10 days. Now I need to get to work on writing the documentation for the project page!

Best regards, Jack

please email info on ssm2166 diy boards whenavailable i am very interested in compressor projects and your project/solution appears to be superior to any of the many others i have seen.also i like the four knobs plus foot switch because it is more like the compression function of studio mixing equipment,i can choose between hard knee or soft knee threshholds plus gain.i am certain that you have seen THAT corps.engeneering schematics for analog engine “one knob squiezer”.i wonder if it would be possible to create stereo compression by tying the ground pins of two ssm2166 modules togather in true ground ? anyway one step at atime.thank you for advancing the art of effects .regards,maxwell lamparello

Would this compressor be a good choice for bass? I’d like to give it a shot!

It will work fine for bass, and all you have to change is one capacitor. The details are in the instructions linked above.

Jack;

You state that “It will work fine for bass, and all you have to change is one capacitor. The details are in the instructions linked above.”

Is this C13, or did I miss something in your online text?

I just ordered the PCB last week and will be doing a build up specifically for my Bass guitar pedal board (first in line of course, driving an octave, distortion and a few other bits).

Also, since I don’t have the PCB yet, what are the dimensions?

David

David, you can use it for bass without any changes. If you like, you can change C6 to 10uF to smooth out the control signal more for the low frequencies.

I love my diamond bass compressor, but I am trying to switch all my pedals over to ones that I built.

My question is can the pedal be run of higher voltage for more headroom like the diamond compressors.

thanks
Ryan
