Two rock gain structure switch

Hello -
I'm pretty sure that i had read in a post a few months ago the actual resistor values for the two rock gain structure switch,but i can't find it now.
I'm building a 50 watt wonderland and i would like to implement that switch.
Does anyone still have that information?
Thanks,
Dimitris

Copied verbatim from that post, a member wrote: "I checked inside a [Two Rock] CLRS V3, the gain structure switch is 1M/(47k/113k/80k) divider. Resistors [are] 47k,33k,33k". I cannot credit the poster as I do not know who it was now.

Hope that helps!

That's exactly what I was looking for.
Thank you Colossal.

I have also seen these values mentioned before on this board. I prefer a pot personally. 47k is almost too low to be usable. 68k like the JM is better

Anyone has a layout for the switch, and where it is placed in circuit?

It is place where the 68k/1m divider is placed in the JM amp and the 3m3/10pf is in an ab763 fender

This should work.
