3 effects in one box... questions.

[ringworm]

I'm wanting to put together a small 3in1 box of effects based on the "Sonic Starstreamer". It's basically a Vox fuzz, booster and repeater in one box.
Is the diagram below a suitable method for wiring a pedal like this, will each effect bypass or engage correctly?
Input is right to left, loose wires are going to the board.
Also, would a single 9v power supply be enough to run all three at once, they are small circuits, originally appearing in plug-in type boxes and also inside the Vox Starstreamer guitar?

looks good to me, I'm not familiar with those circuits but I imagine that if it was originally mounted in a guitar then it must not have been drawing too much current.  A single 9v supply will probably work for it.

Thanks for the speedy reply. I'll give it a go and see how it turns out.

i'm not an EE guru but you might want to do the wiring where the input of the effect is grounded when the effect is bypassed, to avoid noise (specially with 3 effects in one box)...

"i'm not an EE guru but you might want to do the wiring where the input of the effect is grounded when the effect is bypassed, to avoid noise (specially with 3 effects in one box)..."

By using shielded wiring on the inputs and outputs between each switch?

OK, I drew up a little graphic to try to explain this. I'm still a n00b, but this is how I understand it. If I am wrong, someone will correct me I am sure. I drew my own switches so they are nice and big, and easier to follow.

The two switches on the left side are the "standard" wiring. The two switches on the right side could be called, I suppose, the "improved" wiring.  The two switches on the top are with the effect on. The two switches on the bottom are with the effect bypassed.

Your example would be using the standard wiring. Blanik suggested that you use the improved wiring.

With the standard wiring and the effect bypassed, the Effect IN and Effect OUT are not connected to anything.

With the improved wiring and the effect bypassed, the Effect IN is connected to ground.

Hopefully it will help!

I've never seen that kind of wiring before .Mike. I didn't know how to make a ground signal through the switches, I thought if each circuit was grounded from the board that would have been ok. More info for the 'tech' folder, thanks!

I pretty much got it from here, and have seen it around. I just redrew it to help in my own understanding.
