Welcome to the world of Moogerfooger Analog Effects
Modules! Your model MF-105B Bass MuRF is a rugged, profes-
sional-quality instrument, designed to be equally at home on stage
or in the studio. Its great sound and jaw-dropping effects come
from state-of-the-art analog circuitry and quality engineering that
you have come to expect from Moog Music Inc.
Your Bass MuRF is a direct descendent of the original Moog
modular synthesizers and professional rack effects. It contains
two basic functions: a 7-band array of resonant bandpass lters,
a shelving (lowpass) lter and an “Animation” module that
generates sequences of envelopes that modulate the levels of
the 8 lters. Several of the performance parameters are voltage-
controllable, which means you can use expression pedals, MIDI-
to-CV converter, or any other source of control voltages, such as
other Moogerfoogers, to ‘play’ your Bass MuRF. We will discuss
control voltage in more detail later in the manual.
While you can use it on the oor as a conventional effects box,
your Bass MuRF is much more versatile and its sound quality is
higher than the single xed-function “stomp boxes” that you’re
probably accustomed to. The Bass MuRF is a versatile effects
device, it provides an incredible variety of effects. Your Bass
MuRF is a deep musical resource and will become your creative
companion as you explore its possibilities.
The following pages will rst tell you how to hook up your
Bass MuRF and set the panel controls for the ‘basic’ setup. Next,
we’ll explain how the functions of your Bass MuRF work. After
that we’ll go through the panel features and give you suggestions
on how to use your Bass MuRF in specic applications. At the
end of this booklet you’ll nd technical specications, service
and warranty information, Moog Music contact information and
diagrams of the Bass MuRF’s Animation patterns.
