Just finished documentation and youtube demo for a new module. Video is below, a PDF with schematics/parts list and information on ordering a PCB is at http://www.bartonmusicalcircuits.com/skvcf/ PCBs are $8

i was just checking your site the other day for a filter. seems predestined. guess i might need one.
a previous ms20 low pass filter clone i built goes very nearly silent with the cutoff turned all the way down. yours doesn't seem to do this?

Audio rate modulation would be fun with this filter, eh?.....

I stuck two of these behind a 12hp panel and am so pleased with it. I enjoy being able to use them seprately and in series. The build was so easy, I ended up doing both these and the panning mixer shown beside it all in an evening! applause

Nice panels! What design is the panning stereo mixer?

yes nice panels. cool, definitely going to try these filters

So if the two inputs can be used in parallel, then if you build with bananas is the switch really necessary? Or am I misunderstanding something about the wiring/input design here?

Thanks! The panning mixer is another Barton pcb. BMC54 if I'm not mistaken. I omitted the headphone output as I have an output module already.
The panels were done using the drill guides provided on the Barton website, the graphics done with transparent sticker paper. I'm super stoked on them applause

When there's nothing plugged into the highpass filter input, the output sounds noisy and overdriven. Not sure of the technical reason as to why, but I forgot to ground it at first and was disappointed by the sound quality.
