Catalinbread Formula 55


Order now and this pedal will be sent on 25 October!

Catalinbread Formula No.55 is the next generation 5E3 Tweed Deluxe-inspired overdrive. The pedals reproduces the preamp section of the classic tweed 5E3 amplifier in exact detail with the volume and tone circuit replicated part for part just like a vintage 1950s Deluxe.

Catalinbread then expanded upon that recipe to widen the playing experience by grafting the 5E3 preamp section to what feels like a MUCH bigger power section at your pick. The effect of which results in feeling like you’re playing through a larger cab with more than one speaker. All of the tonal characteristics of a small tweed combo but tuned to have the dynamic response of a big amp – woody and resonant!

In place of tubes, the Formula No.55 utilizes JFETs configured for the most tube-like dynamic response and harmonic content. And just like a vintage 5E3 the volume and tone controls are interactive giving you a wide palette of tones and pick responses to choose from. From smokey, full-bodied clean tones to full on raging amp distortion all courtesy of your guitar’s volume knob and/or picking hand.
