The difference is that in an isolated jack the sleeve is disconnected from the chassis, which is usually grounded, so you can lift the ground easily. Edit: search for “insulated jack” on Tayda.

I always wonder why people use transformers if a ground lift will do the same job? What are the pros and cons of either solution?

The solder joints on the switch could be hotter and with more solder. Check out some other build reports. The back of the board is pretty covered in flux and it’s hard for me to tell if all the solder joints are good. I would start with a very thorough visual inspection to make sure they are all...

Keep them coming man! I missed seeing your builds and demos! Always great stuff.

Thanks! I had 4 different attempts with various tweaks. I should’ve used a cheaper material for testing. Oh well.

Welp, almost 4 years later I finally made a faceplate for this.

I built this a couple years ago and I’m pretty sure the switch lets you select a broad or narrow eq shape. It doesn’t quite get into cocked wah territory but the narrow Q is very noticeable with a distortion before it. From JHS:

The switch is a Q control no? Albeit pretty coarse with just two values.

Very nice clean build! No demo? ;)

That said, after further research I ended up ordering some latching push buttons from Tayda. They are not as cool (and probably not as sturdy) as some of the metal momentary push buttons they have but it’ll do for a kids toy.

And btw you can make three latching switches with one single chip which is not bad.

I ended up using a CD4069 and this circuit: https://leap.tardate.com/Electronics101/CD4069/PushButtonLatch/ and it works like a charm.

So who’s trying one of these out?!? Would they work in existing circuits or do we have to make a new one?

Hey guys, I vaguely remember taking a digital circuit class in college but nothing stuck with me apparently… I promised the kids that I would make them a little box with some pots and switches and LEDs that they can play with (my daughter has been calling it her Time Machine [not sure why my...

1) I think that should work, assuming the buffer has a capacitor in the input stage. I would experiment and see. If that does not work, you can put a buffer before the two buffers. That would solve any loading issues but there should be none because those buffers should have a very high input...

I started the mixer and when done I will also experiment!

The master mix cannot keep everything at unity. Voltages are additive, if 1/3 of the signal goes away we get a 1/3 volume drop, right? What am I missing?

You can see matte sand texture red in my latest build report: https://forum.pedalpcb.com/threads/3-way-splitter.27312/

Master bypass would work but then I can’t bypass individual effects? I don’t think you can bypass channels easily. You could just ground the input in the splitter as a way to bypass but then you would get a volume drop, unless the effect was set to wet only… or maybe you had something else in mind?

One thing that I think is missing here that I didn’t realize at first is the ability to turn the mixer and splitter into an actual looper. To clarify: as you said you can blend multiple effects together with splitter+mixer. Now let’s say one of the effects flips the phase: the splitter has you...
