Description from the Wampler website:
We keep on getting asked about a Fuzz pedal. Do we do one, can you do one... Basically, we got the message.
So, we did what we always do, Brian locked himself away and when he emerged sometime later to show us what he had, it was clear he had created a monster... A pedal so aggressive, so tonally destructive we seriously considered whether it was right for us to release it.
What we at Wampler Pedals do is make pedals that retain your tone and add to it, not smash it into a million pieces. Once we had got over the sheer brutality of it, we noticed something strange... Something about the sound... Brian has created an uber aggressive fuzz pedal: not only does it destroy your tone, it somehow also manages to retain it... Each guitar still sounded like itself when played through it.
Here it is, the Leviathan Fuzz. A true monster. With complete control over the tone: volume, gain, bass and treble and a switch that changes from a roar to a rumble feel. The switch takes you between GE and SI diodes, allowing you to more precisely shape the nature of the sound between a more compressed but gainier sound, or an open, throaty tone. Let your imagination guide you... Switch it a few times to get the hang of its sound, and from then on you'll know when you want to rumble, and when you want a roar!
