I set my new Super-Sonic Twin next to my Red Knob "The Twin" with a ABY pedal, set a Fishman SA220 on the outside of each for vocals, plugged in my new Les Paul Custom, and played a four hour gig. The Twins are powerful, and the Super-Sonic complemented the Red Knob perfectly. It took two decades of experimenting, failing, getting close, almost having my sound to finally get it the way I want it. Super-Sonic Twin matched with a Red Knob...nothing like it. Thank you, Fender.
