Cool, let us hear how it goes. As for the 4 knob version there is an additional "Clean" control which sort of blend your clean signal with your overdriven signal. You could try a signal splitter? Here is what one of the builders have to say about it:
The point of difference with most of these is the “Clean” knob, which “uses Class A Mixer technology to split the original signal and the Stellar Drive signal, giving you the option to combine both signals. The Clean knob function is so much more than your average blend knob, because you have two knobs (Level and Clean) to dial in any mixture you want, not just the boring 50/50 ratio in traditional ‘blend knob’ pedals. The clean knob is absolutely cutting edge.”
