Hello. I want to mod my PT-80 delay so that I can hear the trail of Delays as I switch it off.
My research points to buffered bypasses and not "true bypass" which is the one I am using on all effects.
What I did was route the output of the delay to the pedal output and ground the input in the "off" position of the FS. So I get what I need. I can hear the fading delays as I turn it off and I can keep playing my guitar. Though when I turn it off I get a huge volume drop on my guitar. It seems as if the guitar soundwave flows into the output of the effect so I get a much reduced amplitude in the amplifier. That is how I perceive it.
I found a ton load of references to buffered bypass switching circuits but I can't make anything out of it. I did try to use a buffer on the input of my circuit but that seemed to ruin all. Maybe I did something wrong.
I give you the schematic of the PT-80 and the buffer I used.
