Re: KOD DS-04 traced [schematic]
Is the output resistor possibly 470R instead of 470K?

Re: BAJA Kiwi Merry Christmas Wah Wah pedal 221219 [documentation]
Loads of variation!
Any suggestion for a value for C3 to approximate the Q of a 33k resistor in parallel with an inductor?

Re: BAJA Kiwi Merry Christmas Wah Wah pedal 221219 [documentation]
Nice, I like that it is buffered bypass as you could easily retrofit it into an existing wah enclosure and use the SPDT footswitch that most have.
Is the Q response constant or does it vary with the sweep like an inductor wah?

Re: Xotic - Soul Driven [traced]
Interesting, sort of like a Zen Drive-ish front end with Bass boost section is taken from the Boss BD-2 followed by a transistor output buffer.
Topology/values for the bass boost section match the BD2 but with switchable boost. Same diode protection and preceding volume control.

Re: TC MojoMojo
My guess is same topology as TC Dark Matter with different components values. Schematic for the Dark Matter: https://www.freestompboxes.org/viewtopic ... er#p270842

Re: TC MojoMojo
Dark Matter Schematic is here. Possibly uses the same board as the Mojo Mojo with different values and/or a few different parts. There are unused parts places on the Dark Matter boards.

Re: BAJA Highway 1 [documentation]
Nice project!
Interesting looking tone control. What is the 22n cap in parallel with the 3.3K resistor doing? What is there frequency response of the Bass and Treble controls?

Re: Baja Trembulator schematic, board layout and circuit boa [documentation]
I presume the 100K resistor to ground before the Depth controls is redundant when used with the added output buffer version?
Presumably it was acting as a pulldown resistor on the output in the original version.

Re: Caline Mark 4 [schematic]
Look at the MI Audio Tubezone for some tone control ideas.
The topology of the Caline appears to be a simplified version of the Tubezone.

Thanks.
Are the parts with a cross through them not fitted on the circuit board?

Re: Lehle Parallel, schhematic [schematic]
Why is the Vbias so crazy asymmetrical?
Could they have not just reference the Bias resistors to ground as they have a + and - power supply for the pampas?

The Mid control is a gyrator.
You can use this calculator to figure out how to change the response.
