We know that fuzz is fuzz, but there are plenty of different flavours out there and we all have our favorites among them. So what if we got the sounds of several of fuzzes in a single pedal? 

Okay, we’ve seen the digital modeling pedals that offer you the likes of Fuzz Face and Big Muff sounds in one place, but what about an analogue pedal that does a similar thing while retaining tradition by using transistors exactly like all classic fuzz pedals do?
