God I love Big Muffs.
 
This is a Kemper pack of 40+ profiles using three different vintage and boutique big muffs. They were created using a variety of guitars with options for just a Muff into the amp AND a collection of different overdrives to add flavour, power and intensity to the tones. All running through a Marshall JCM800 into an Orange 4x12 miked up using a Royer R121 and Shure SM57 through Great River Preamps. Each pedal combination is dialed in to it's sweet spot so you can just plug in and play!

The pack contains at least 4 profiles of each pedal combination, including:
1970’s V4 Big Muff Pi - One of the original Op Amp Big Muffs, this is the same model used by Smashing Pumpkins on Siamese Dream.
V4 Big Muff Pi boosted using a Keeley Oxblood.
V4 Big Muff Pi boosted using an Ibanez Tubescreamer.
Black Russian Big Muff -  These have an absolutely unreal low end that I find is just as useful for bass as it is for guitar, I also find them way more open and detailed than the more modern Big Muffs.
Black Russian Big Muff boosted using a Boss Blues Driver.
Black Russian Big Muff boosted using a Mesa Flux Drive.
Union Tubes and Transistors Tsar Bomba - An incredible sounding Green Russian Big Muff Clone, lower gain and more detailed than it’s EHX cousins with a wonderful midrange.
