🇺🇸【 Catalinbread 】 Formula 5F6 Tweed Bassman-style 
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!
Controls
VOLUME: This is the master volume that controls the output of the pedal. The lower you set the Gain knob the higher you’ll want to run the Volume. For the best clean and on edge-of-breakup response, turn the Volume all the way up and start with the Gain control at minimum and then slowly bring up the Gain control to the desired response. This will give you the most authentic Bassman experience!In general, for best results the pedal should be set to be *slightly* louder when on compared to bypassed.
GAIN:The Gain knob controls the gain, obviously, but circuit-wise it is identical to the “Bright Volume” control on the tweed Bassman. So, turned down low, you’ll get those great sparkly cleans, turned up midway or so and you’ll get that elusive touch-sensitive response where you can play clean or dirty just by varying your picking attack. And cranked all the way up you’ll get the gain structure of a Bassman on 12, thick and overdriven, but still sounding very California. 
TREBLE, MIDDLE, and BASS tone controls:
These controls reproduce exactly, part-for-part, the tone circuit (“tone stack”) of the tweed Bassman. If you’re familiar with the tone controls on that amp, you’ll already know how these work! The circuit was carefully tuned around this tone stack to give great tones, no matter how the tone knobs are set. Don’t be afraid to try things like full Mid and no Treble or Bass, or even full Treble with no Mid or Bass. You’ll find a huge universe of useful tones to make your part stand out in the mix.
In general, the higher you set the Gain knob, the less Bass you’ll need. And, the lower you set the Gain knob, the less Treble you’ll need. So, the optimum setting of the tone controls will be determined by where you’re running the Gain knob. This is true for the real amp as well!
The Middle knob can be thought of as a sort of other “gain” knob. The higher the mids are set, the more dense and focused the tone will be. So if you’re going for the maximum cranked sound, try cranking the Middle control as well as the Gain. Conversely, if you’re going for the cleanest sound, try reducing the Middle but boosting the Treble and perhaps even the Bass control.
You could just set all the tone knobs at noon and go from there but also try this: start with all the tone knobs at minimum. You’ll hear that the pedal is producing the full tone but it is not getting out. This is because the tone stack is later in the preamp, after the two gain stages, as opposed to later black- and silver-face designs which put the tone controls way up front in the preamp. Anyway, so with the tone knobs at minimum, play and begin increasing the Treble control until it feels about right. Turn the pedal offand on so you know the difference between the bypassed sound and what the pedal is doing. Then slowly bring up the Middle until the sound fills out enough. Finally, you may decide you don’t need any Bass boosting at all. An exercise you can try to get abetter feel for the tone controls is turn the pedal on and off and try to set the tone controls so it sounds the same on as it does off. You won’t get the exact same tone but you’ll learn a lot by trying this exercise and find that the tone knobs can often be set much lower than you would initially think.
