Schematic/Wiring for A/B + C Loop Switcher?

[giovanni]

So,

I was Reading the article, but it was very confusing for me...;S so i can't decide what buffer its better or not...or which is like the one used on that pedal...



Wich one is that?

Can you guys point me a diagram with a buffer and how its connected so i can build my own version of that pedal?

For example: https://www.pedalpcb.com/product/jfetbuffer/

hi guys, i hope i'm not late for the party, i'm looking for something like this:

One Control Minimal Series White Loop

A/B Switch and Looper for Effect Pedals Flash Loop function selects between Green Loop or Red Loop, High-quality BJF buffer (switchable), Can be used as a tuner output / mute switch, 2 DC Barrel plug outputs (2.1 x 5.5 mm, centre negative) for...

Any of this diagrams represents whats used on the pedal above?

Thanks

ANOTHER idea is to get Robert's 3-CHANNEL SPLITTER.

Then from your guitar you'd go into the one input, and have 2-channels/loops to switch between and a dedicated always on TUNER OUT.


To complete the loops, get the 3-CHANNEL MIXER.

The MIXER would act as the RETURNs for your two channels. If you left the TUNER OUT as described above, you'd have a spare input channel for playing MP3s or triggering sound-fx OR you could make it a full channel that just so happens to also have the tuner in it.


Far more robust than the One-control. The flip side is it would take more pedalboard real-estate with a larger enclosure to handle the footswitches you'd be adding to the Splitter or Mixer.

I'd recommend having the SPLITTER as the main controller and adding the footswitches to that, 'cause you've got volume and phase on each channel. The MIXER could be an under the board set-and-forget 1590N1.


If that all seems too much, I can break it down for you and/or try to come up with something closer to the One Control —better yet though, is to describe what your exact needs are, and then we can see if there's a custom solution that fits your needs to a "T" — this is why we do DIY, after all, because stock commercial stuff isn't quite doing what we need it to do.

So ... @CrustyD3mon ... what do you want exactly?

You can have a separate buffer for each loop;
the buffer could be on the send or the return of each loop;
you could even have one loop with the buffer on the send and the other loop's buffer be on its return.

OR

You could have one simple master buffer on the looper's master input (or its master output, or both).




Each/any of those buffer positions could be bypassed with a toggle (or a stomper, but that would then have to be a huge box).
