Catalinbread Formula 5F6



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 play as 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-off. Adding the Formula 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.

When a tweed Bassman is set at low to medium volumes, you get a sparkling, harmonically rich tone. Turned up a bit more and it delivers that famous on-edge-of-breakup character that is responsive to your picking attack, a sound so craved by guitarists. Play a ringing open chord and you'll be rewarded with lush harmonic swirl. And then crank the volume up to 12 and you'll get a thick, creamy, meaty crunch - the original genesis for all heavy guitar sounds to come. And if you hit it really hard, you're rewarded with a slight compression, a slight sag in the response, that feels so good to play. The tweed Bassman is so touch-sensitive and responds beautifully across the frequency spectrum. If you play a Strat, this is a match made in heaven. Gibson style guitars sound great too and will overdrive the preamp sooner and you'll start to recognize those tones you heard on famous records.

With the Formula 5F6 you'll get that entire range of response!  It does that quick compression on the initial attack that 'exhales' quickly into a wide clean with lots of glassy chime on top and a tight full low end.

Wait, there's more! After we got the Formula 5F6 circuit dialed in to reproduce the beautiful vintage tweed Bassman response, we asked: "Hey what if we supercharged and gained this thing up but pretended we had never heard of a Marshall?" Some tweaking to the gain structure and tone circuit and boom! We got a great new voicing - much higher gain, a bright attack, and as full as you want it. And still voiced very American! It was so cool we decided to build it into the pedal, accessible through an internal switch...
