Building upon our initial tribute to the iconic sound that sparked countless riffs, the EHX Satisfaction Plus offers an extensive range of tones, from the classic '60s growl to smooth lead sounds and deep, earth-rumbling sludge. Elevating the original Satisfaction Fuzz circuit, the Satisfaction Plus Fuzz incorporates a modern control set featuring a FAT/NORM mode switch, Bias control, and Tone knob. The added FAT mode presents a more expansive and warmer tone compared to the NORM mode, perfect for velvety leads and massive, thunderous riffs. The Tone control, an active tilt-shift EQ, inversely adjusts both treble and bass frequencies of the fuzz, enabling extensive tonal modifications. Use the Bias control to fine-tune the fuzz character, ranging from balanced and open to tight and snarling.
