Comet Trails – the result of too much Mountain Dew.

After several days spent crafting the code that makes up our digital secret sauce, we found ourselves one afternoon surrounded

by 10 empty cans of Dew, and sounds from another world. We rushed from the ofﬁce, shouting to anyone who would listen,

“Dude! Check this out!” Now that same caffeine and sugar-fueled rush is available to you at the stomp of a Filter Modeler foot

switch. Somewhere inside your Filter Modeler are seven ﬁlters, all chasing each other around and looping back and forth across

the great expanse of sonic space. We call it Comet Trails…FREQ controls the range of the ﬁlters. Q controls the width of the

ﬁlters. SPEED sets the rate of the ﬁlter movement. MODE controls the Gain of the whole shebang.

Spin Cycle – inspired by Craig Anderton’s Wah/Anti-Wah.

This effect takes particular advantage of the Filter Modeler’s stereo capabilities. Imagine two wah pedals panned left and right

that work in the opposite direction from each other. One goes up while the other goes down. Now add the fact that these wah

pedals are sweeping from minimum to maximum automatically. This is what headphone mixes are made for! When operating

in mono, the wah and anti-wah will be united on the single output. On this model, the MODE knob is used to adjust a “peak

follower”, which can be used to make the speed of this effect sensitive to your playing volume. FREQ controls the range of the

ﬁlter emphasis in the wah tone. Q controls the width of the ﬁlter. SPEED sets the speed at which the wah effects sweep. MODE

controls the amount of Volume Sensitivity for the speed of the effect.

Throbber – inspired by the Electrix

Filter Factory.

Like the LFO section of the versatile Filter Factory, the Throbber alters the brightness of your tone with an emphasis on a spe-

ciﬁc frequency that you can select with the freaky FREQ control. Q sets the amount of emphasis from purring to howling. This

effect is perfect for those hipster Electronica sounds, and we’ve also noticed U2’s The Edge making appearances with a Filter

Factory in his rack. FREQ targets a speciﬁc frequency range for the ﬁlter. Q controls the width of the ﬁlter. SPEED sets the rate

of the LFO. MODE selects between four different wave shapes (Ramp Up, Ramp Down, Triangle or Square).

V-Tron – Voice Box meets Mu-Tron III.

In this model’s sonic playland, your guitar again “speaks” with an almost human voice, but now it does so in response to your

playing. Each time you strike a new note or chord, the vowel sequence will be “spoken.” You can choose whether the speaking

will go from the start vowel to the stop vowel and call it a day (UP Mode), or turn around and come right back again (UP &

RETURN). FREQ controls the sound of the starting vowel (a, e, i, o, u). Q controls the sound of the stop vowel (a, e, i, o, u).

SPEED sets how long it takes to “speak” from one vowel to the other. MODE chooses between the two modes: UP, or UP &

RETURN.
