Any one ever attempted to add a bass boost filter a la m3 to CK2III?
According to several posts I've read, this amp sounds very neutral.
Sometime ago I built an m3 with bass boost and I absolutely love it, but the casing is too big for my desktop. So I decided to build a CK2III and in case it is too neutral I would like to enhance the lower end freq.
Any help on how to implement the bass boost, if possible of course is appreciated

The M³ bass boost implementation cannot be done in the CK²III because it has no global negative feedback loop.
