Anyone do buffered bypasses?

[YouAre]

I'm just curious, does anyone here do buffered bypasses instead of true bypass?

Can you show me a schematic or a switching logic/layout?

I tend to do true bypass when building,

There are arguments for and against.
Just to stir it up a little http://www.petecornish.co.uk/case_against_true_bypass.html

I think a buffer is a good think used properly, like I left my wah with the buffer and resisted the trend to make it TB as its at the front of a long pedal chain and I think the buffer is better there than TB.  That may be considered wrong in some peoples eyes and right for others

I cant think why I would build an effect with a buffer in it on bypass though. Unless you really needed to for some special reason....

Buffered bypass seems to generally mean that a mechanical switch is still being used, just that the bypassed signal has passed through a buffer at some point in the pedal, electronic bypass meaning that there is something non mechanical doing the actual signal routing (CMOS analog switches, FET switching).  Some pedals both buffer the bypass signal and switch it electronically (like boss (FET buffer usually, FET switching) and Danelectro (TL072 buffer, CMOS CD4053 switching).

A basic buffered bypass is easy, you send input directly to the buffer, buffer output to the circuit, and use a SPDT switch to switch the output jack between the buffer output and the effect circuit output.  Super simple.

I've used a buffered bypass in a stereo output pedal, to switch both outputs and an LED with a 3pdt stompswitch.  That was using the GGG FET buffer and it sounds great.

You might even want to try the Clinton Bypass. See "The Technology of Bypasses.

i tried this

                                                                   >>>input of byoc808 --------output  [|]
                                                         /
input >>>>>>>> GGG jfet buffer>>>                                                                          [|]  --------------output
                                                        \
                                                                                                                       [|]


the [|]'s are lugs of a 3pdt if you didn't get that.

It worked, but i got a loud pop when toggling between both settings.....ugh, i had a thread earlier bout the damn popping i get with this effect
