Elephant Stomp Boxes is a Boutique Pedal Builder.
They make Hand-Wired, High Quality reproductions
of Classic pedals.
The BUFFER is a necessity when you're running more than 18-1/2' of guitar cable...

It uses a JFET OpAmp IC. It’s a simple circuit for purity of tone.
The switch is only to see what it does to the guitar signal.
