My favorite control on any amp is badcats edge knob. Not sure what it does in regards to circutry, but it adds the zzz into that sound. The valveness. Its on the hotcat 30 an maybe some others. Having that valvness zzz to incorporate into any amp would be heaven. I have it on a badcat xtreme pedal wich is a hotcat preamp section. You guys could always copy that.
