Need some experienced builders to review the wiring of my future builds

[Dullman8]

Hi everyone,

I'm kinda new to all this and try to grasp every single aspect of effects building.

I'm wanna be as sure as possible that I won't spend hours trying to figure out why stuff won't work, so I'm asking for a little look at my projects.

I found some verified layouts (that I'll slightly modify as you can see on the wiring schemas, but it doesn't involve major changes and thus probably no building issues), but I'm wondering if the wiring of the circuits (several effects in one pedal, how everything gets to the switch etc).

For each project I'll send the layouts and a wiring schema I did so that you guys have everything to help me.

Thanks a whole to those who will give me a hand and help me start on this electronics journey!

I apologize for not taking the time to closely examine the diagrams you posted yet, but I can offer a bit of advice that might seem obvious, but here goes.

Make sure each circuit is working right on it's own before you combine anything. Myself, I would get super confused and probably really frustrated if I was trying to do it all at once, ESPECIALLY if I was perfboarding everything. Troubleshooting the project as a whole would be a nightmare for me. Therefore, first confirm everything is copacetic with each submodule. Are you powering the whole thing from an external power supply or a built in? If the latter, that would be the first thing I would confirm. Make sure power is routed to everywhere you need it nice and cleanly. Then test each circuit on its own. Rule out any issues there. Once all circuits are happy, then you can deal with the switching and input/output routing as its subcircuit.

I like to deal with things like this in digestible chunks. Even a circuit itself can be troubleshot that way.

With a project like this, there is a lot of off-board wiring of pots and input/output connections/switching plus power. It's easy for it to become a rats nest. Best to be super neat and keep wire lengths reasonable and if you can incorporate any sort of modular connectors, it's worth it.

Good luck!

^ all the above, plus welcome to the forum. and - collect a datasheet for each transistor type number you will be using - confirm he part in your hand matches the layout orientation and the circuit diagram. ohh, yes, CIRCUIT DIAGRAMS, you really do need those, to check for errors and to show us when/if goes thing wrong.

put each of your resistors on your dmm before you solder - save us all heaps of typing time. learn how to name pot lugs properly, universally, without resorting to numbers. see over at geofex.com, secret life of pots, et al.

familiarise yourself with capacitor numbering and markings, or ask us here - there's a few tricks to watch for. also switches, learn the naming conventions - any on/on/on switches used in yer intendeds? and datasheets for your IC's, so you know which way is up. and most importantly - don't do a mirror image flip from layout dia to real-life board.

If you're new to electronics and stompbox building, my advice would be to start with something simpler than (rather complex) stripboard builds and multi-effects. There's too many things that can go wrong and debugging can be pretty frustrating. My first build was a simple kit with step-by-step instructions, for example. Most people need a few easy successes before they are ready to deal with the unavoidable failures  .

And definatelly NOT layouts utilizing C-B-E and C-E-B pinouts for the very same transistor type..
(like the first one..)

+1 agree. I don't like that layout much at all. It's also got wire links under the chips and two wires down one hole. Ugly.

Hey everyone!

Thanks for your answers, and osry about the late reply, it's been quite busy around here.

I'll keep your advices in mind, thanks a lot! Now, I still wonder if my wiring makes any sense... Consider it like an "exercise", just to see if I understand how this whole thing works. If you have any more time to look at what I did!

Thanks again, I hope y'all are having a great day!
