Peter built a Double Six and modded the tone controls. “With the help of a friend I have made some small modifications on the Double Six and now I LOVE it. The modifications covered the tone stack and we have added two DPDT on-on switches to increase the low frequencies, pushing the spectrum towards low-mids or increased high-mids.
“The mid pot is now a push-pull pot. In the normal position it connects the Boost switch with the ground through a trimmer pot to get two steps of boost.”I plan to do the grille nicely in the near future, but still do not have an idea, how. I am very staisfied with this amp. I have put a Fane 12′ Alnico speaker in the combo and it is also suberb.”
