Millenium 2 with bicolor LED?

[cheeb]

Can this be done? I have a DOD A/B box that I want to put in a bicolor LED in to represent the channels. The LEDs I have have two legs like a usual LED. I just wondered what would need to be done to have this installed in a Millenium Bypass.
Thanks for any help.

I'm not familiar with this pedal but if it just a A/B box Yea it can be done,do you know a supplier of 5mm bi-color LEDs? I'm needing some myself.
Why millennium it,you don't want a 3pdt or something?

I just already have everything I need to do a millenium and just use the switch that's already in it. 3pdt's are expensive and I don't like having to wait for them to get to me. I'm just worried that if I install a bicolor led the normal way, it will work on/off instead off color1/color2/off.

I think you need a little logic (as in chip) to do what you're asking.

I don't have time to draw a schematic now, but I think you could do it with one extra transistor. In the Mil 2 circuit bypass the LED so the R(led) goes from +9V to the drain of the FET. Have an NPN transistor with emitter connected to GND, Collector to +9V via Resistor (same value as R(led)). Bicolour LED goes between drain of FET and collector of NPN tranny. Drain of FET goes to base of tranny via resistor.

I haven't tried this. Draw it out and see if it makes sense. I could draw it when I get home.
