TUBE ZIPPER
envelope filter + distortion
Congratulations on your purchase of the truly outrageous Tube Zipper. The Tube Zipper is
two effects in one, a warm sounding Tube Envelope Follower and a rich tube Distortion unit.
When these two effects are combined into the same circuit the outcome are entirely unique
new wild effects. The Tube Zipper uses two premium 12AX7EH vacuum tubes.
Carefully reading these instructions will ensure that you will get the most out of your Tube
Zipper. We urge you to sit down with your Tube Zipper and spend some time learning exactly
how this pedal works. You won't regret it!
Your Tube Zipper comes with a unique 12V AC/1000mA adaptor. Use only the adaptor
supplied. Using any other adaptor can cause harm to you and the Tube Zipper.

ENV Switch (UP/DOWN) – Selects the direction of the filter sweep.

INPUT GAIN Knob – Boost the input signal before the filter. When the INPUT GAIN is
turned up, it will yield tube distortion.
DRIVE Knob – Adjusts the amount of distortion after the filter. As you turn the DRIVE knob
up, past 12 o'clock, the overall volume of the pedal will begin to decrease. Simply turn the
MASTER VOLUME up to compensate.
SENSITIVITY Knob – Determines how sensitive the filter sweep is to your playing. Use this
knob to adjust how far up or down the filter will sweep when you play.
FREQUENCY Knob – Sets the peak frequency of the filter when the envelope is not active.
When the envelope is active, the FREQUENCY knob determines both the start and stop
frequency of the filter sweep.
RESONANCE Knob – Determines the RESONANCE or Q of the filter. As you turn the
RESONANCE clockwise the filter will become increasingly sharper. When the
