Wiring up two circuits into a single enclosure setup?

[Jbassfunk775]

Hey guys, I need a bit of advice/guidance on making a "2 in 1" effect.. Basically I have a bunch of pcb & strip board fx I've built over time & about half as many enclosures (not to mention not enough pedalboard space).. And there are a number of circuits that either;

1) Have to potential to compliment each other nicely, like a 3 band active eq with mid freq & a TS-style or other low-mid gain overdrive circuit. Or ~>

2) Two similar fx that sound great & are useful on their own but you wouldn't want to run at the same time. For example, I built a Demeter Fat boost & an ep-boost clone. Both are wonderful do different things well but they're both higher voltage/headroom clean boosts with fairly full eq . The 2 circuits would be great to have in a box where I can either select them individually via individual foot-switches, or even just selectable with a 2 way toggle or similar..

I'm familiar with one of the diy project pcb sites having breakout boards available for doing this (guitarpcb.com I think?) but any input you guys have id absolutely appreciate!!

Just wire the output of one effect to the input of the other... then each effect has true bypass... just think about it as REHOUSING 2 pedals to a new home..

Each circuit's 9v power should have a 100 ohm resistor to the 9v power supply to decouple the circuit, and maybe add some caps to after the resistor to filter out some noise or something like that...

Interesting enough..
(could you post a draft schematic, plz..??)

P.S.
Resistors don't decouple anything..
(capacitors do it..)

I don't know your exact scenario, but I can give you an example of one of mine.

I made two PCB effects. One was a simple, three knob, PT2399 delay and the other was a simple, two knob, AccuTronics Belton Brick style reverb. I would typically run them at the end of my signal chain, delay first, reverb second. I did tend to notice that I'd keep both effects on, but would adjust the volume of either effect and leave it that way. And I noticed I typically was wanting them either both on, or both off. So I eventually made a new PCB which was just both effects together in series with one true-bypass switch.

I don't know if this was the "right" way to do it, but it worked for me.

I was replying quickly because i had something to do afterwards

i was gonna say add some caps after the resistor.. didn't  know how to say it though...

Here are some resources:

https://www.madbeanpedals.com/tutorials/downloads/MBP_FootswitchWiring.pdf  The last page shows one foot switch wiring option for a dual pedal to get you thinking, there are many other variations and I won't opine on which one's "best." 

https://aronnelson.com/diywiki/index.php/Frequently_Asked_Questions_(DIY_FAQ)  Lotsa stuff about lotsa stuff.

Thanks! I love it when someone explains something by breaking things down their most basic form and suddenly a light bulb 💡 goes on and it's like "Ohhh Yeahh of course!"

Awesome thanks!!
