Craig Anderton Rocktave Divider

This is a great project that is featured in Craig Anderton’s Book – “DIY Projects For Guitarists” and also featured in a Guitar Player Magazine column that is linked below. The layouts that include modification options are provided courtesy of Dean Hazelwanter. Thanks to Dean and also Mark Hammer for posting the schematic and article. PLEASE NOTE: Dean’s layout is for a TL074 type (pinout) quad opamp instead of the pinout for the 4136 as listed in the article.
