anderton tremolo

[fuzzo]

Hi , I redraw the anderton's tremolo and I would know your opinion about these schematics :



I keep all part from original design, espacilly the switch "square/triangle". I changed the "signal structure" to add a volume control.



I put a pot. instead of toogle switch for the "square/triangle" shape (like Boss TR2)

I don't think the square/triangle potentiometer will work, since it's in the feedback network.  However, if you put buffers between the LFO and the blend potentiometer, it might be okay.

at least buffering the triangle output with one of the unused inverters wired as inverting unity gain amp seems neccessary.

For these buffers I can use unused input of CD40106 ?

if the unused CD40106 in fact is a CD4069 as mentioned in the schematic: yes.

yeah, it's a CD4069 or which used in Anderton tremolo.

I'll add the buffers and post .
