Thoughts on variable NFB control in Fender Bandmaster57-Style PA
#2
I think you may run into stability issues fi you use the original layout. With a layout with galactic grounding and such you won't have any issues with the variable negative feedback. However, I don't think a 50K presence control is a good idea. The range of the presence control in the stock model is fine plus because you are going to be varying the negative feedback you will be negating the effectiveness of the presence control at certain settings.
