Axess BS-2 Vero to Schematic

[aviherman5]

Hi all,

I have this Vero for the Axess BS-2 which is a super cool buffer used by EVH himself. I was going to put a higher resistance pot in it in order to get a boost.

I want to make a PCB for this but, alas, don't have a schematic. Does anybody have one?

If anyone wants to draw one up, I wouldn't complain hahahahaha

Thanks for your help!

Any chance this is right? Just drew it up

It was quicker to draw than for me to find an on-line schematic which showed all the right elements (frustrating).

There's a 22pF from the opamp + input to ground.

Basically a non-inverting preamp driven from +/- 9V.    Very small amount of gain, 1k feedback R and 4.75k to ground.

Here you go.


It also works well with a switchable boost at the end, using the other half of the op amp, the response is still quite flat.

Amazing! Thanks everyone for your help!
