PEDAL FLANGER (MUTRON)
Introduction
It doesn’t seem that long ago, as a teenager in the seventies, I took in a vast array
of music both past and present. Contained in this music were passages where the
guitar was transformed into something seemingly magical.
As I entered the world of music as a vocalist, I soon discovered what some of these
devices were and how they produced these “magical” sounds.
This is one of those devices……….The Mutron Flanger.
The original flanger incorporated the SAD1024 delay IC for its 1024 stage “bucket
brigade” design.
The circuit reproduction offered here follows the same path but with the more
accessible MN3007 1024 stage IC retrofitted in its delay line.
The original design included a transformer mounted in its enclosure.
This reproduction offers a design that can be powered by either an 18VDC center
negative source, or a 12VAC wall transformer. No switching, no component
changes, no circuit board jumpers required!
I would like to thank the many generous people who helped to make this flanger go
from a few bad gut shots and an illegible schematic, to a working device that truly
does produce “magical” sounds!
Greg (Govmnt Lacky), Federico (Fender3D), Ian (Ronan), and the venerable R.G.
(R.G.), Aron for providing such a great meeting place for like minded people -

And last, but certainly not least…..
A very special thank you goes to my partner in crime….Dino (Digi2T)
Who without his dogged persistence, constant nudging, keeping me on track,
answering my countless questions and inquiries, and offering up his flanger for
dissection……..This project never would have got off of the ground.
