From the vendor
Project overview
You can now get the same tonal versatility, sensitivity, and harmonically rich overdrive as the famous Dave Friedman’s Small Box amp, all enclosure inside a pedal.
Introduction
Freeman Crate is the pedal version of the all-tube amplifier known for being one of the most flexible and touch-responsive amplifiers on today’s market. This little overdrive board can deliver mighty rock ‘n’ roll tones while still being surprisingly versatile!
The circuit has the same intuitive control set as the amplifier, letting you dial in the exact tone of rock you want, from vintage Plexi to high gain annihilation. Whether you want a high-output cleaner tone for pushing your amp hard or a thick rough drive that will sit well in both classic or modern rock, all you have to is sweep of the gain control and get there in no time.
