Wondering what this mod is for.
About to build an ep as a unity only buffer, and another as an actual boost with master vol.

I may have answered my own question here....
It looks like it may be a unity gain mod..... if so then how about this:
Put the gain pot on a 3pdt footswitch, replace the last 47k resistor with a 100k resistor
and a 100k pot in parallel, run the wiper of the pot to the 3pdt and switch the boost pot and the
new output pot at the same time? Now it's a buffer and a boost.
This is assuming you always want it on and or want to move the bypass to a regular toggle.
Why didn't xotic think of this? Will there be strange noises switching the gain pot in on the fly?

This is the Eco Booster with Kenny Mod, of course! :wink:
This is the most deranged piece of schematic artwork I've seen coming through here... :scratch:
where's the original blog?

Is that finger paint? I can't tell if I love it or hate it, but I'm sure I feel strongly about it.
