I'm trying to make a friend of mine's old(block logo) MXR Noise Gate/Line Driver Pedal true bypass with 3pdt switch,led and power jack.Here's Andreas(stinkfoot) page on how to make older mxr pedals true bypass with a dpdt switch; http://stinkfoot.se/archives/537 He didn't go into using a 3pdt switch.He talks about stealing power from the board for the led.I'm just not sure where to steal the power from?Here's the schematic; http://www.freeinfosociety.com/electronics/schemview.php?id=569 Any help would be greatly appreciated! :icon_biggrin:

Collector of T1; or any "+9V" point.

Ok cool!So,I can use the 22k resistor that's connected to T1 as well?
no, the collector goes strainght to 9V. you'll still need a current limiting resistor. if there's a power jack it may be easier to tap the 9V from there, or at least la little less messy.
