The Catalinbread 5F6 is our take on the classic tweed Bassman-style amplifier from the late 1950s.Utilizing 2-6L6 output tubes into 4-10" speakers, the Bassman quickly became the mainstay of stages everywhere during that era.

The Formula 5F6 adds vintage tweed Bassman response to our range of Foundation Overdrives, giving you the awesome characteristics of this classic amp into any clean amp.Do you play a high-powered clean amp such as a Twin and can’t get a good cranked response at the real world gig volumes you have to play at? Do you play a smaller amp at home but it’s still too loud to give you a great amp response? Do you have a two-channel amp but hate the dirty channel? Or maybe you can playas loud as you want but you crave more touch-sensitivity in your rig. Or maybe you’re having trouble integrating fuzzes into your rig; maybe they get too loud or they just don’t sound right because your amp tone is too clean and the dirty channel of your amp makes the fuzz sound thin, farty, and pinched-o. Adding theFormula 5F6 to your rig will solve all these problems and will become the foundation of your pedalboard, the pedal that will enhance the response of all your other pedals.The Formula 5F6 lends itself to almost any musical style, from the classic Strat - Bassman blues tones ofBuddy Guy and Otis Rush to artists like Jimmie and Stevie Ray Vaughn, Robbie Robertson, Robben Ford, all the way to heavier styles by stacking boost, overdrive, or fuzz pedals into it. Don’t worry, the Formula 5F6won’t just make you play old music! It will take you where your imagination takes you!
