On January 1970 Led Zeppelin hit the stage of London’s historic concert hall, Royal Albert Hall. At this performance Jimmy Page expressed himself masterfully with a broad pallet of tones and GIANT dynamic range. Of course this has a lot to do with Page’s playing technique and Gibson Les Paul. His backline amps, custom Hiwatt heads into Marshall cabinets filled the entire hall with a cornucopia of colors at levels ranging from a mouse whisper to rave ups louder than a jumbo jet taking off only inches over your head.

At Catalinbread we love the RAH performance, but we hadn’t considered the possibility of capturing it to put into a pedal… One day our friend Charlie got ahold of Catalinbread’s chief circuit designer Howard Gee to ask if we could do it. Charlie said that he’d been trying to get this tone for years and told Howard, if anybody could do it would be Catalinbread. Having proven his ability to capture the essence and experience of famous amplifiers, Howard began experimenting with what is now the RAH.
