My build progress

Yes, s/Kassutronics/Barton/.

The Barton JFET Phaser is indeed two boards stacked. It’s mostly an all pass filter with a JFET, a capacitor, an op amp, and five resistors… and then repeat that eleven more times.

Nice and clean work

Mmutant and FM just finish .only I need Connect 3.3v light to button ride side

Try replacing the leftmost resistor with a 1M pot. Added: To be a little less terse, the first part of this circuit has the inputs going through 100k resistors to the inverting input of an op amp. The non inverting input is connected to ground and the output feeds back to the inverting input through another 100k resistor: [image] This is an inverting amplifier whose gain is the ratio of the feedback resistor to the input resistors: 100k/100k = 1. Increasing the feedback resistor would increa…

Heres Sams super simple mixer w/ gain control.
Big ups to the local wizard here pointing this out, this models a killer utility to have corralling percussion and boosting the stragglers. I simply replaced the 100K feedback resistor with a 1M pot. I hope somebody finds this as useful as i did. I mean who gets stoked over a mixer rite?

This is sams super simple mixer w/ gain x10

I need to build one of these myself. The only mixer I have in my case is a crappy stereo one that is useless for CV.
