Hi all, I just bought all the stuff for my pedalboard this year (so I haven't had it for very long)...
...the SD-1 on my board (I'm using a Boss BCB-60 pedalboard) powers up in the "on" state (ie: red light is on) when I plug in the pedalboard.
My DD-3, BD-2, and TU-2 do not do this (although the TU-2 light flashes on for a second or two then goes off).
Is this normal for the SD-1? Or do I have a bad pedal? |

yea thats normal.
Some pedals start in on instead of off.
My SD-1 does the same thing (same with a couple others) |

my GE-7, TU-2, EH-2 and MT-2 all start "on".
no idea why it happens though! i would guess just a factory setting? |

| I heard the digital pedals but that kinda means nothing to me as I don't know which is what besides a name on the case. |

It's because the flipflop circuit that controls turning the pedal on or off doesn't have a preferred start-up state. Its startup state will be determined by small differences in the components used. The most important parts are the two transistors and switching them around will usually make a pedal that starts in the on state come on in the off state instead.  |

Yeah i hate this sorta too, since my RV-2, DD-2, AW-3, DS-1 and CS-3 are all on when i plug power in. That's quiet alot power and i fear that my supplier might not take it all one day |

Don't worry about it - the pedals draw the same regardless of if they are "on" or "off". Some pedals will draw a mA or so more when the LED is lit, but that's about it. As soon as power is applied, the circuit is drawing current.

In other words, BossMan-01, according to Murphy's Law, if there is any possibility to get your supplier burned then, it will get burned. Doesn't matter whether your pedals are on or off when you plug the pedalboard.  |

| I like it when pedals start in the on state. I use a DMC switching system to switch pedals in and out of my signal path. My pedals are always "on". A question for Stinkfoot or Bossarea: If I swap the two transistors in the flip-flop circuit will my "start off" pedals become "start on" pedals? |

On the flip side, my EH-2 blinks on when I power down the powerbar
When I turn it on, the DS-1,SD-1,PH-2,BF-2 and PS-5 all come on and you can hear some weird static going up and down from the phaser n flanger.
All powered through a NS-2, but that one doesn't 'auto-on' |

I don't really get what is the problem between "start on" or "start off" since the amp should be the last gear that you turn on. You can turn on, or turn off, the effect in your pedals and nothing will be heard until you turn on the amp. Maybe you want to save a few seconds every time you start to play.
If the "Start on/off" condition is due to small differences between the flip-flop bjt's, and those differences aren't intentional, I think there might be "start on" and "start off" versions of the same pedal. If that is true, ebay sellers should begin to declare what version is it.
"DD-5 NOS, Mint, w/box&manual, Start On" |

Perhaps it matters in conjuction with the old Boss SCC-700 series Sound Control Center which made possible the ability to turn up to 7 compact pedals on & off, determine the connection sequence using computer control, & could also store up to 32 types of effects in memory like is shown in The Boss Book pg. 98 that Neil Schon used.
It be neat for Boss to release another control center but since some pedals turn ON when power is applied while others are OFF, I'm not sure quite how the SCC-700 or a new controller would work. |

SD-1 starts in "on" state
