Octave pedal in it's earliest form was a fuzzy nasty pedal that produced an octave up effect if played around the 12th fret with the tone knob rolled off. In more recent years, pitch shifter pedals have given us the ability to produce clean octave up and octave down tones
Still, these early crude octave pedals such as the Tychobrae Octavia or Green Ringer were used to great effect and produced some great tones
Many years back I fancied myself one of these old school octave pedals. With an infant in the house and no disposable income I decided to learn how to build one of these beasts. With the abundant information on the internet and a lot of trial and error I got into the hobby of pedal building.
Below is a demo of the pedal that came to fruition based on my shear determination and want of a simple Octave Pedal.
