  1. hmm, I've never had a boss switching system apart, but usually these things run off a flip-flop switch (it's a type of circuit that basiclly flip-flops...changes state when triggered)


    these (usually you'll see them as their own IC) usually have S and R (SET and RESET) inputs -- if you drag one of them high, it will force a switching state (S forces the switch's state hi and R forces it low).

    So, when you want a definite "power-up state" , usually one of the S/R input will be tied to ground (so it's always logic lo) and the other will be hooked up to a little RC net off the supply so that, at power-up, you get a logic pulse that SETs or RESETs the flip-flop's state

     

     

    Boss uses FETs for switching, not an IC flip flop.

  2. Maybe Mike Matthews got sick of people asking him what it was so he rammed his head against the wall in aggravation and after coming to said, "rams head"

     

    Seriously though, there was an interview on the web somewhere with Mike, probably on The EH Man's site, about how it was just a drawing a friend of his did that he liked.
