On the official Rocket Series Octavia product page, Octavia inventor Roger Mayer reports that Relf received one of five late 1968 wedge enclosure Octavias.

Rocket Series Octavia Product Page

[15.] At the end of 1968 I decided to build a limited run of 5 or so Octavias and 5 Distortion Pedals all housed in the wedge enclosure.

[16.] EMP and Tychobrahe derived clones.

All the clones I know come from this later series of pedals.

This latest series Octavia configuration used a driver section comprising of complimentary NPN PNP low noise silicon transistors driving a commercially obtained iron audio driver transformer. The biasing used for these units were also varied to provide evos that were designed for up to 24V operation for recording studio work to a version that would use an internal 9 Volt battery.

This series of pedals used the type of knobs you can observe on the EMP example.

[17.] These units were completed in early 1969 and went to guitar players like. Syd Barrett - Pink Floyd Steve Marriot - Small Faces, Peter Frampton - Small Faces. Keith Relf - Yardbirds and Jimi of course.
