*All tracks recorded to directly to line input of mixer into sound card. Only levels were adjusted, no additional equalization, no compression.
FREQ is center frequency, pitch when resonating. Range: 8Hz-6kHz
Expression input via TRS.
F CV input via 1/8" jack. V/octave response, good tracking over 5 octaves.
Plug in modulations or use as a VCO.
Q is quality factor, one over bandwidth,
resonance.
Pronounced around noon. Self-oscillates 'round 3.
Q CV input via 1/8" jack, 0-5V effective range, summed with Q control.
Try with modulations, envelopes, etc.
GAIN is bipolar,
at minimum, we are
notching the center
frequency. And at max,
boosting.
TILT is flat at noon,
shelving on either side.
From low-pass to high-pass
response.
VOL is volume. Unity gain
is around 2 o'clock.

This was the best video manual and art I’ve seen in a long time. I will be picking one up soon!

You guys deserve two awards for this. One for the video and one for the pedal.

[@lepistanuda]

really really cool video. Also nice to stress the importance of EQ and demonstrate how creative it can be.
I wonder if you should add an *epilepsy warning* for the ending though.

Would you guys ever make an envelope filter/Auto wah or does the Long Life already cover that ground ?
