Stand alone life pedal octave section

[Bobbyd67]

Hi everyone!
I am thinking about making my own stand alone pcb of the octave section of the life pedal. Looking at the schematic it seems to include the first jfet in the circuit. I know the green ringner uses only 2 2n5088/89 and a 2n5087. So if I would do it should I make it from dist_in to pin 2 of the octave pot or should I start at c3 ? I do love how it works on the life pedal and I would be curious to try it with other effects !!! Thanks !!

It’s the green ringer with a jfet blend circuit like this

cool Thanks ! then would this schematic work ?

i am not sure if the out is at pin 1 or 2 of the octave pot :x

Ah!!! Looking at the layout of the blend circuit it says output to pin 2

You got it right. You even have the diodes facing the right way! Any JFET with a reasonable high Vp will work. I'd put C1 after R2, but that's just my opinion. I'd also be inclined to use film caps for C6 & C7. 220nF is plenty large for both.

Thanks Chuck !!! I will OSHpark it and try it with film caps
