Catalinbread Formula 5F6


Order now and this pedal will be sent on 27 October!

Catalinbread Formula 5F6 is the sound of a vintage tweed Bassman, 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?

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. The pedal won’t just make you play old music! It will take you where your imagination takes you!

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.
