Voice tailors the top end response. Middle is brightest. You have 2 darker positions.. might use darker ones with strats or teles.

Dave sounds great, clearly your most flexible amp to date, great job!
I take it Thump is a 1M pot in place of the 220k fixed depth resistor, Response is a 100k? pot, or 47k+50k pot? in place of the 47K NFB resistor? If so that means you're probably tapping off the 16ohm tap?
EDIT: From sweetwater gut shot I think I see 8ohm tap -> 1M/.0047uf Thump -> 27k NFB resistor -> Response Pot (value?) with a 220k across the outer lugs -> presence.

Ya Dave, why don't you just tell Crazynutz the whole damn amp Circuit.

He has already divulged a lot of info to us on this and other forums. Dave is quite generous with sharing information, and ideas. As a matter of fact he has been so generous, that he corrected several errors on schematics the community has created. He has nothing to hide. BTW if he doesn't want to share he can clearly decide not to answer for himself.
I didn't see anything in regard to this, but noticed in the photos from the SweetWater page...did Dave put a new FX Loop in this?!? He used to use the SDM/Metro loop, then his own with the 2 trimmers. This is like the old Metro loop, but doesn't appear to be that either and why it looks like a new loop is in the new BE-50 Deluxe?!? Is that so?? If so, is it just for the BE-50DLX or other of the latest models also??

It's a re layed out loop board. That's it, been that way for awhile. Few changes and a great ground plane.

Some euro dealers have it. Or have them on order. Combo might be possible just trying not to make it to large.

re: the response pot. It's probably a 250k that he's already stocking for use as the treble control in all the amps. The 220k resistor turns it into an approx 100k pot, so the effective NFB resistance would go from 27k to 130k or there abouts. And he doesn't have to keep stock of yet another value pot. But what the hell do I know....
And man, am I ever looking forward to hearing one of these amps in person. Just sent an email to the local Friedman dealer to see if they are gonna have any in the new year.
My BE100 is the last version with the Mallory caps, and I never updated it because it just sounds so freakin' good as is! . That may end up being a good move, because now if I pick up a BE50, they'll be different enough to keep both

You are correct, the response pot is 250k. The BE50 quite a different beast (based on the sound, and some tracing out the schemo), much more aggressive capable. It would be worth having both be100, and be50dlx in my opinion.

Thanks for the info
My local Friedman guy hasn't gotten back to me yet. Gotta follow up on this tomorrow.
