Electro-Harmonix Satisfaction Plus Fuzz

Overview and History

The Satisfaction Plus Fuzz is an evolution of the original Electro-Harmonix Satisfaction Fuzz, which was initially released as a tribute to the biting, treble-heavy fuzz tones of the mid-1960s British Invasion. While the original pedal focused on simplicity and historical accuracy, the 'Plus' version introduces a suite of contemporary features to address the needs of modern players who require more low-end presence and tonal flexibility.

Manufactured by the New York-based Electro-Harmonix, the pedal retains the compact form factor of its predecessor while adding significant internal circuit adjustments. It is positioned as a mid-priced utility fuzz capable of bridging the gap between vintage 1960s 'maestro-style' clipping and modern high-gain distortion.

Technical Features and Controls

The pedal is distinguished by its expanded control set compared to traditional vintage fuzz clones. The primary controls include Volume and Attack, which dictate output level and gain intensity, respectively. However, the addition of the 'Fat/Norm' switch and the 'Bias' knob provides deeper circuit manipulation.

• Fat/Norm Switch: In 'Norm' mode, the pedal delivers the classic, bright 60s character. Switching to 'Fat' mode injects additional bass and warmth, making the pedal suitable for heavy riffs and modern rock contexts.
• Bias Control: This dial adjusts the voltage or operation point of the transistors, allowing the user to move from a balanced, open sustain to a 'gated' or 'starved' sound that sputters and snarls.
• Tone Control: Unlike a standard low-pass filter, this utilizes a 'Tilt EQ' design. It simultaneously adjusts both treble and bass frequencies, pivoting around a central sweet spot to ensure the fuzz remains articulated regardless of the amplifier's character.

Sound Character

The sonic profile of the Satisfaction Plus Fuzz ranges from thin, velcro-like vintage textures to thick, earth-shaking sludge. In its standard settings, it provides the 'hairy' lead tones associated with early rock and roll. When the Fat mode and Tilt EQ are engaged, the character shifts significantly toward a wall-of-sound effect with increased sustain and low-frequency resonance. The Bias control further expands this palette, enabling rhythmic, 'staccato' fuzz effects when turned toward the gated side of the dial.

Comparison and Suitability

The Satisfaction Plus Fuzz is primarily suited for guitarists who find traditional 60s fuzz pedals too limited or thin for modern live performances. While the Electro-Harmonix Big Muff Pi offers more sustain and a smoother, 'violin-like' character, the Satisfaction Plus provides a more aggressive, raspy grit that cuts through a mix.

Compared to boutique or entry-level alternatives, it offers a balance of price and features. It serves as a more versatile alternative to the standard Satisfaction Fuzz and provides a different texture than the EHX Big Muff with Tone Wicker, which focuses on high-frequency bypass rather than the Tilt EQ and Bias manipulation found here.
