This is a Custom "Civil War" Big Muff Clone w/ RARE NOS KT3102E (made in the USA by CBC Pedals) I had built for a specific project. This pedal has the ability to swap transistors with ease. I'll include some stock silicon transistors, and some Soviet KT3102E transistors as well for more clipping and a more vintage sound (look in the pics to see the sockets which make installing and uninstalling transistors quick and easy). This fuzz is about as gnarly as it gets, and can do anything from Dan Auerbach, to David Gilmour, to screaming metal. Let me know if you have any questions!
