3) Make sure the effect is on, and MIX is at 10. 
4) Connect just the “left/mono” output to your amplification
You may want to experiment with the panel controls and switches 
as we discuss each of the parameters.
5) Now, play a bright, sustained sound, preferably of low pitch into 
the Bass MuRF. Figure 6 shows the MF-105B’s basic frequency 
response, the response that you hear when the panel controls are set 
up as in the basic setup. For a moment press the bypass switch and 
turn the effect off. Note the change in the character of the sound. 
Now switch the effect back on.

filter.  When you have learned the sound of each individual filter, 
try various combinations, such as the bottom two and top two. 
Note that even without Animation, the Bass MuRF is a VERY 
POWERFUL filter bank with many possibilities to sculpt your 
tone!

can be shifted up and 
down by a small amount 
to create an effect similar

a graph that portrays the 
results of shifting a filter’s 
center frequency. In the 
Bass MuRF this can be
