I don't have a demo but it is just a simple switching.
3 sets of send/return-1 for clean effects(like comp,chorus,etc),1 for crunch effect(like OD,etc),and 1 for lead effects(like Dist,OD,Fuzz,etc).If only using 1 delay then global na yung delay and connected after the switcher.
first button is for lead/rhythm switching,and while on rhythm mode another button switch for clean and dirty rhythms(just like eric johnson switching setup).one box lang ito at may built-in noise gate.
