The Sonic Shroom expands on the best tones of its predecessor...the AB-Synth!

The Sonic Shroom is a harmonic-blasting, liquidy, layered fuzz--with controls that take you from smooth and  
searing to splattery! From there, add a mind-altering second mode with wild oscillation, whale calls, blips, self-
arpeggiation, more synth tones, and fat octave down! As wild as the oscillation can be, it's also musical...plus, you
can play over it: the oscillation only kicks in when you're not playing, letting you sustain long notes until it devolves
into feedback and blips...or letting little chirps and squeals jump in between the notes of your solos. The Sonic
Shroom is a trip you need to take!
What users say...
"This pedal gives me new inspiration to different sounds and new songs."
-Anders, Norway

"So many fuzzes of this type have no real way to tame them but this thing is Dr. Jekyl and Mr. Chong, so to speak."
--Jeff, AK

"This little guy is a blast. Cool fuzz tones and the perfect noisemaker w/ the flip of a switch...Fuzzy madness &
oscillatory goodness all in one."
--Nick, IN

"Let me start by saying this pedal is NUTS! I absolutely love it. I've never had so much exploring a pedal. This was
my first FuzzHugger purchase but it most definitely won't be my last. I'm super stoked on this pedal."
--Matt, CA

"The oscillation became a really great addition to the sound since its so tweakable."
--Mike, FL

"Holy freaking CRAP.....i just did a video demo of the AB SYNTH and that thing is SICK! One side of it is a VERY
GOOD sounding high gain fuzz...nice decay, very natural sounding, plenty of sustain. Hit the switch, and goes
bananas. I was able to get some REALLY cool sputtering and noises with it. BUT...it sounds like a normal fuzz as
long as you are PLAYING, but as soon as you let a note sustain for a few seconds, it starts going seriously weird. I
was able to just move my left hand up and down the scale, and have it bass fuzz out on me...very strange and
beautiful. And as a fuzz, it sounds really good! It's a high gainer FOR SURE..I never felt the need to stack it with any
other gain or boost."
--Bobby, FL

"This thing has loads of fuzz on it, I cannot even begin to explain. Even at its minimum it has a lot and it just gets
thicker and bigger from there. You can get some pretty interesting lead tones out of it. Depending on the settings it
can clean up decently with the vol knob of your guitar. The texture knob is very useful, from blistering thick fuzz to a
rather calm distortion like tone."

Sonic Shroom vs. AB-Synth.
Basically, the Sonic Shroom is the AB-Synth V3.
· The first thing the Sonic Shroom does does is bring back all the sizzle from V1.
· It keeps the Trip/Voice knob, but substantially expands its range, letting you get into
some more bite and crunch.
· It drops the Clip knob and replaces it with the original Osc knob, which I've decided I
prefer to have on board, for more control over oscillation and filtery tones.
The FuzzHugger Sonic Shroom
The Controls!
· Right Footswitch: On/Off.
· Left Footswitch: Activates Trip Mode for oscillation.
· Trip/Voice knob:
· In
Fuzz mode, this knob adjusts VOICE...from full and thick to the left, to tighter and crunchier to the right!  
· In
Trip mode, knob-left gives you lower pitched oscillation, and droning cackles. To the right, you'll get higher-
pitched blips and squeals. (Dial in blips as you blips as you roll back the Fuzz knob).

· Fuzz knob: Increases gain and overdrive. From high-gain to higher, increasing focus and sizzle! The last tiny turn
of this knob compresses the fuzz for a splattier, over-fuzzed sound.
· Oscillation knob: This is your main oscillation control, which is activated when you turn on Trip mode. It adjusts
the oscillation being feed through the circuit, altering intensity and character of the oscillation.

Trip Mode (both footswitches on):
· All knobs affect oscillation in this mode.
· First-time users, start with your guitar’s Vol and Tone turned all the way up!
· For weird synth bass tones: Roll back on your guitar's Vol knob!
· For blips: Turn Voice knob toward the right...start with Fuzz knob turned full right, then start backing it  left.
· Trip Mode requires passive pickups. Also, no buffered-bypass pedals in front of it.
