Hair-brained idea - by-pass switch with three or four parallel on/off switches

I have a two channel pedal board presently (thank you Boss OC5) and want to run different distortions on each side of it. Doing that independently is simple enough, but I'd like to be able to run multiple distortions on each of the channels - in parallel rather than series - and be able to turn any one or all of them on and/or off.

SO . . . .

Thought was to use a master by-pass switch that sidesteps the parallel signal chain and four individual on/off switches so that a clean signal is not present when the parallel circuit is active.

I intend to use two-color indicator foot switches to make it obvious what state things are in, and isolate ground utterly for both power and signal.

Is this even POSSIBLE? As I think through the circuit options I keep running in to input or output or both silencing the entire box.
 
Hey Knucklehead,

Totally possible.

The best way I see is a relay type of system. As far as I know, PedalPCB has nothing like the following, so I hope it's okay to post links outside the realm of PPCB.


Check out this Radio-Button switcher https://diy.thcustom.com/shop/effect-control-v1-0-pcb/.
Combine the 5-channel radiobutton relay system with a spluffer and mixer and a master bypass... might be able to get it all working to your satisfaction. You don't have to use all 5, you can run as many channels as you want (up to 5).

There are different modes for the buttons that you can choose from:
—Mode1: standard switching On/Off for each channel
—Mode2: real radiobutton-mode (One channel is active at any time)
—Mode3: fake radiobutton-mode (One channel is active but can also be toggled off – unit bypass)
—Mode4: cycle through channels (up and/or down using one or two momentary switches)

There's a few more options for doing something similar at THCustoms; I'm not sure what PedalPCB has in this regard, but I'm pretty sure the radiobutton-channel isn't among them.


JMK offers the Paralyser, a 2 channel parallel splitter, you could combine two of those. Alas, currently sold out.

GPCB has the ParaMix which would also accomplish two channels parallel on either side of your dry (or OC-5) channel.

Of course, the Paramix is based on an Anderton design (IIRC), and you could do it with even more channels on vero.

The above or a combination thereof should accomplish what you need.

Thanks so much for the forage material - I have two Life pedal projects to finish before I pursue this so I have time to digest what you've linked to.

MUCH appreciated!
