The Formula 5 is the first device in Catalinbread's acclaimed Tweed lineup, designed to recreate the classic, touch-sensitive tones of the 1950s with simplicity. While it shares similarities with the Formula 55, its gain structure is distinct.

This pedal uses circuits that emulate real tubes, providing a generous amount of gain that interacts beautifully with your guitar’s controls, harking back to a time of just one player, one guitar, and one amp. 

All controls are interactive, with the Tone linked directly to the Gain, allowing for various "sweet spots" tailored to any amp-and-guitar setup. At maximum gain, you can achieve a light, chewy sag or, with the gain backed off, allow the rich Tweed sound to shine through.

The Formula 5 accepts anything between 9V and 18V with a centre-negative DC power supply. Plugging in anything other than this (centre-positive, AC, higher voltage, etc.), there’s a good chance that the Formula 5 will be damaged. It’s not ideal! Save yourself some time and headache and plug the correct adapter into the pedal the first time; otherwise, you run the risk of voiding your warranty, and that’s just not rock ‘n’ roll.
