Electronic Switching Question

[Rayman]

If the Boss electronic switching uses two JFETs to to isolate both the effect circuit in and out, why would you need an input buffer?  If the JFETs are "off" then there is no load on the signal and the effect circuit is theorectically isolated.  Wouldn't that essentially be true bypass?  Any help is appreciated.

i think you would need a buffer and float/bias the signal accordingly...
i dismissed this type of jfet switching and kind of designed my 4066 switching...

Congratulations. You have reinvented the Clinton Bypass.

The Clinton Bypass (for which, see "The Technology of Bypasses" at GEO, http://www.geofex.com ) was named for our dearly departed president William Jefferson Clinton, who once testified under oath that "I don't think you can prove what I said was not true." This later turned out not to be the case, but it was the inspiration for the Clinton bypass. I don't think you can distinguish it from True Bypass.

However, even with the Clinton Bypass, you would still need a buffer to keep the effect from loading down the guitar in effect mode.

GEO has articles pretty much plumbing the depths of bypassing if you read the articles.

Thanks, I'll check out the info on GEO.
