i want to put 2 effects in one box kinda like this http://www.generalguitargadgets.com/pdf/two_in_one_wiring.pdf
but i want to use one 3pdt stomp to turn on effects and a toggle switch to select what effect i use. i will never use both at the same time. i want to put the bazz fuzz and electra in the same small box. but i really dont want to use 2 3pdt stomps.

Use the 3pdt to bypass both effects.
 Run the input and output of the 3pdt to the dpdt center lugs.
 Wire one side of the outside lugs of the DPDT like you would an effect minding input to input etc.
 The other side [like you'd bridge for bypas] can be wired for the other effect instead of bypass, watch input from switch to input to effect [same for output].
Convention creates following, following creates convention.

thnx for help. taking it a step further, how can i hook up two leds, 1 for the electra and one for the bazz fuzz. so that the led goes on only when that pedal is being used and off when it is not.

3PDT is easy to run an LED indicator on/off is done with the 'third' Pole and Double throw of the 3pdt.
 The Millenium Bypass allows use of LED for 'on' indication of effect with a DPDT.
 The way I described uses the '3rd' switch of the '3'pdt to run the LED...and would indicate 'total' bypass or effect on...not which one.

Isn't that possible by using the millenium bypass on the DPDT toggle and put an extra transistor buffer into it like a flip-flop situation (Ibanez and Boss pedals)? This way you switch between 2 trannies that each drive a led.

what i did in my dynaross squeezer:

i made a dyna/ross comp with the switch so i can choose between those 2 and i made an orange squeezer.

my 3pdt switch is wired as i would normally do, the third throw connects 9v to a 1k resistor wich is connected to the "-" side of both leds.

then there is a 4dpdt toggle switch that switches the input from the 3pdt to one of the circuits. the output is switched the same way.
the other 2 throws are connected to ground and switch between led1/ground circuit2 and led2/ground circuit1

i stuffed all that in a small enclosure.

i think you would need two 3pdt switches for using a different led for each pedal (one stomp switch, and one toggle)

use two rows of the toggle to do the effects switching, then use the third to choose between two leds, but put the third poles of the 3pdt switch in series with the les so it will switch on/off with the effect

i hope that made some sort of sense  :?
