Wiring 2 or more circuits into one enclosure?

[steveyraff]

Hey guys,

I just finished soldering all the components into a delay PCB I bought online. Its a build for a friend. He's now wondering can I make it a double pedal with a second footswitch for a drive/booster. I was going to use the AMZ booster with it as I've built those on vero a lot before.

I've never joined two circuits up like this. I had been thinking about it recently for another project too. My own pedal board for my band only has a Keeley Compressor, Mooer Boost and a Tuner. I was gonna rehouse them all into one enclosure, but again, its something I've never done before.

I'd be grateful if someone could explain the process to me, or even if anyone knows of any good wiring diagrams for doing something like this and could maybe link me.

Thanks!

You absolutely can!  It's really easy.  I don't know how the delay PCB is hooked up to a bypass switch, but typically what you'd do is take the wire from the bypass switch that is going to the output jack, and hook it up to the next circuit's bypass switch, where the input jack would typically connect.  Does that make sense?

Make sure everything is grounded and you should be good to go.  Just remember, the input jack connects to the first circuit's bypass switch, and the last circuit's bypass switch connects to the output jack. 

Here's a diagram from tagboardFX:



I don't hook up my 3PDT switches like this, but my first few 2-in-1 pedals I did it this way.  You can do it however you wire up your 3PDTs though.

Thats great - thanks! I'll have a proper look into when I've time this evening. Cheers.

Yes, that's the way to do it.  I'd be sure each board has a "star ground point" that then connects to chassis via 1 wire from each.    And, each board should have its own "power conditioning"....9V to the PCB, and a BFC reservoir cap to ground. 

Probably not crucial but at times, it could be.

Gonna start wiring these two circuits into my finished enclosure today. Might need to summons y'all for some more help along the way lol. I had presumed the LED's would need to have their resistor values lowered, but then again, I guess the same 9v is going to both.

I foresee great difficulties ahead - wish me luck!

Ok. All wired up!

And here is my first question.

Before even plugging a guitar in, I have powered it up. I am using a vero and a PCB (boost and delay). The delay PCB has its own LED pad. Right now I've the two LED's wired up as in the diagram above - not using the pad on the PCB, so that LED is currently not working.

How do I incorporate this into my build to make it work?

Check the polarity of you Leds

So, if you switch the switch on, you are completing a circuit from 9V to ground going through the LED and resistor. This shouldn't involve the PCB at all. It's in the wiring, most likely, based on the diagram. Do you see 9V at the anode of the LED when the switch is engaged? I don't know how big the resistors need to be here.

Edit: ^^ and what jimilee said.

Sorry guys,

Already sorted this problem out. Faulty LED ! ! It was all wired and working correctly. Cheers!
