Yup. Might as well throw a pot in there instead of a three-way. It'll give you even more control.

I have this done to many of my amps. Pretty sure you gave some info for my BE100 years ago.

You haven’t begun to show how versatile it can be to mod the NFB circuit. Try putting something like a 220pf cap across it. Of course different types of caps will change the sound as well. Try a 250pf silver mica. Tinker with value and types.

You should include reasons or speculations as to what would happen with certain values and types for example sake, and I like reading your shit on here.

I don't want to lead the witnesses trying it out.You should include reasons or speculations as to what would happen with certain values and types for example sake, and I like reading your shit on here.
Did I mention diodes in the NFB circuit? How about no NFB resistor at all? What about using inductors?
I didnt even bring up depth circuits which are a part of he NFB circuit.

Understandable, the more simple "a lower value here will increase this or that" in theory stating.
I've lurked for many years and I always enjoy your technical posts. I work on my own stuff and have electronics background (amateur/mid level technical wise but doing the work wise its very good) but I love working on these things. I read most of your input regarding modded marshall designs.
