From the web:
The Black Spiral II Fuzz is a versatile and aggressive fuzz with a unique blend of vintage tone and modern technology. This new version features a wide-open Bias Control, three discrete voicing options, a hybrid tonestack (mix of the Brute and Allora), and gobs of output. These changes make it a darker than the original version, the emphasis is now on fatter rhythm tones and horn-like leads.
