Question about pedal bypass
« on: August 05, 2020, 04:36:39 PM »
What's up friends! my doubt is this.

It is well known that for a bufferless circuit the bypass wiring is like this. :P





Now my question is if the circuit is buffered, how would the wiring be? :icon_eek:


Thanks for your time, greetings!

Welcome to the forum... :icon_biggrin:

place attach lug 7 to the start of your buffer, and lug output of your buffer. A schem would help nicely.. :icon_biggrin:

So there should be no wire connecting 7 and 9 now

It really depends. Do the circuit have an input buffer, an output buffer, or both? Do you want the buffer(s) to stay always at the signal chain?

Welcome. The switch wiring is the same. The only things that changes is the positions of the buffers.

A circuit is a circuit is a circuit..
(fully buffered, semi-buffered or unbuffered..) :icon_wink:

Despite its own buffering status, 3PDT switch wiring shouldn't change at all..

P.S.
Gord, I can't see any reason for utilizing two useless buffers in bypass mode..

As the title says - it's "buffered" bypass - not "true" bypass. If you look inside most Boss type pedals - that's effectively how the bypass works - input buffer - circuit - output buffer - with circuit either switched in or bypassed. The bypass switching is buried inside the overall circuit. Sometimes you'll see one or the other buffer excluded - so you'd only have either the input (most likely) or the output buffer. All the red bits are the same circuit.

Maybe this will help you:

Title says nothing either about buffered or unbuffered bypass.. :icon_wink:

As it's expessed by OP:
my question is if the circuit is buffered, how would the wiring be? :icon_eek:

makes me understand he wants to bypass a buffered circuit (by true, fake or whatever bypass method adjective..)
Can't see any reason for In & Out buffers to be wired right after and before IN & Out jacks respectively rather than PCB IN & OUT..
(unless of course, lugs 7 to 9 jumper wire DOES need buffering..) :icon_wink:

Possibly - I took the question as meaning something else.

Can't see any reason for In & Out buffers to be wired right after and before IN & Out jacks respectively rather than PCB IN & OUT..

I explained that already - see my previous post.
