Classic sounding fuzz. I was given it but as I have a load of fuzzes already - and use a Chase Bliss Automatone II - I can't justify keeping it. 

ELECTRO HARMONIX SATISFACTION FUZZ 
GUITAR PEDAL / STOMP BOX
Introducing the Satisfaction pedal from Electro Harmonix.
Back in 1968, guitar amps were intentionally engineered to keep players from experimenting with distorted sounds. Electro Harmonix changed all that.

For 40 years Electro Harmonix have been proud to contribute to many of the most famous recordings in music history. Our circuits won't ever constrain the color of your sound; rather, they give you the freedom to find it.


SATISFACTION 
EHX re-creates the classic fuzztone pedal with the Satisfaction Fuzz, now updated with true bypass circuitry for optimum signal path integrity.

The Satisfaction Fuzz features an elemental two-knob layout with controls for Volume and Attack (fuzz).

True to the genre, this classically-voiced fuzztone creates a sound that is anything but subtle and goes from an aggressive rasp to full-on fuzzed-out mayhem!
