THE
OVERVIEW
UNPLEASANT
SURPRISE
Experimental Fuzz/Gate
Reminisce about the time you got your shoulder
caught in the reciprocating saw while this unit destroys your slick jazz lines.
The fruit of an oddball circuit, hanging there awkwardly by some parasitic effect. Tweaked, bended
and shoe-horned to optimize it’s stench, it’s unpleasance. The time has come to turn all dynamics
to shit. Strangely, it feels very natural.
As The Unpleasant Surprise turns your playing style
upside down, you’ll be thankful for its ability to
push you outside the box, outside your comfort
zone, all the while retaining the essence of what
is played. The artifacts created by this pedal are
strange, harsh and unusual but never seem misplaced or out of context.

USING THE UNPLEASANT SURPRISE
The VOLUME control is self-explanatory. Unity gain is around
noon but who cares. Use it to slam your amp or the next
pedals in line. Turn it down if the anguish is overwhelming.

Gain/Gate threshold
The ONSET control affects interstage gain, which happens
to mimic an inverse gate threshold. Turn it up for more
saturation, longer sustain. Down for sputtery ad-lib farts.
T Simple output treble cut.
G Affects amplifier bias. Open or Saturated. Allows
variations in distortion grain. Note: the difference
becomes less noticeable as the ONSET is turned up.

C Feedforward. Crushes your signal to shit. ONSET

sound good using your typical center negative, regulated

not desirable nor recommended. There is no battery connection inside the pedal. Always check your power supply
for proper voltage and polarity before connecting.
