Good afternoon everyone, Its been about a week or two since I got the Catalinbread Formula 55 pedal, so I figure I could write a few words on it. It is a Fender Tweed styled OD pedal. Its not completely taking over the amps character, think of it as adding a tweed flavor to your sound. It really does nail the sound and characteristics of a Fender Tweed amp. I believe they based the pedal on a Tweed Deluxe. On the green channel you get that chime that fender is known for. Roll up the volume and it gets FAT, but the higher notes still retain their clarity. Just strum harder and it breaks up. Play softer and it sounds almost clean. I really don't use the red channel that much, but its fun to play around with. its just a higher gain channel. Build quality is great, feels solid. It is advertised as "hand built" and I can definitely tell. Inside you'll find the initials of one of the employees (not sure if its a quality check off or who assembled it). Overall, its a great pedal! Gives that classic tweed tone, and excellent quality. It was $239 through Sweetwater. Also worth mentioning that Catalinbread makes more of these "flavored" OD pedals. They have a Marshall one, a Jimmy Page style, I believe a Hiwatt styled OD and lots more like that. Im eyeballing their Echorec delay pedal. Based on the Binson Echorec from the 60s. This was just a quick review, if you have questions or something I didn't go over, please feel free to ask.
