The Volcano device is a one-knob fuzz pedal inspired by the classic Fuzz Face. It was designed by the people from EQD at Akron, Ohio to have the ultimate classic fuzz tone with a big low end and a biting top end without being too harsh. It features an input buffer and a pickup emulator (transformer) to make it pedalboard friendly. The Bias knob controls the voltage fed into the transistors, allowing the user to dial in the desired tone. Additionally, two internal trimpots are included; one acts as a volume control and the other, ‘Bias+’, allows for fine-tuning of the main bias knob. The Volcano device is a great choice for guitarists looking for a classic fuzz tone with a modern twist.
