I've been trying to figure this out for decades...does anyone know what kind of fuzz Erik Brann used on "It Must Be Love" from the Iron Butterfly "Ball" album? The "grinding" sound he gets on the middle and outro guitar solos doesn't like a Fuzz Rite to me...or anything else I've ever heard. I've tried to duplicate the sound using an original Fuzz Rite, Ashbass FuzzBrite and Catalinbread FuzzRite, using various guitars and amps, to no avail. And if it was a Fuzz Rite, how did he get it to sound like that? It also sounds like he's using some other kind of fuzz on some of the background parts...or at least set the pedal differently. I'm looking for that metallic "grind" as opposed to the buzz, sputter, splat or moan you hear from most fuzz boxes. Anyone know?
