The ehx satisfaction plus fuzz is a modern twist on the classic 60s tone that launched thousands of riffs. Delivering an extensive range of hairy sonics from creamy leads to thick earth shaking sludges this pedal is perfect for guitarists looking for a vintage tone with contemporary features. Those include things like the fat norm mode switch bias control and tone knob to place broad tonal shifting at your command. The fat mode injects extra warmth for those massive mainline riffs while the bias control affects the fuzz character from balanced and open to gated and snarly. The tone control is the real magic behind the satisfaction though as it hides a tilt eq that affects both the bass and treble of the fuzz letting you dial in the hazy sweet spot with ease!
