The Protoboard Chronicles

[Big Monk]

So, I have officially retired “The Prototyper”, or my 1590DD based breadboard environment.

I completed my Protoboard, added a few things to it, fixed some issues with my 3PDT hack job and now I’m off am running.

First up will be a blend/mix pedal for use with my Mooer E-Lady. Many options here of course. First one up is a 2N5088 buffer before the mix control:



I’m not terrible familiar with these circuits but I’ll try an op amp buffer and JFET buffer feeding the mix stage as well.
