From the post
The marketing: The Catalinbread RAH was built specifically to nail Jimmy Page's gigantic guitar tone from Led Zeppelin's legendary 1970 performance at Royal Albert Hall. At the time, in contrast to the Marshalls that he eventually came to be associated with, Page was using Hiwatt heads on stage, modified for a bit of extra gain. The resultant sound, as captured in the Royal Albert Hall concert DVD, is enormous, and the dynamic range from these high-headroom amplifiers is nearly symphonic. With the Catalinbread RAH overdrive pedal, our good friends at Catalinbread have managed to squeeze the distinctive "Jimmy Page Hiwatt" tone into a compact stompbox. Starting with their WIIO pedal as the foundation, and combining some elements of the Dirty Little Secret, Catalinbread delivers a unique overdrive pedal that will reward the player who appreciates articulation, real dynamics, and a very amp-like response. The Catalinbread RAH is an ideal foundation overdrive pedal; just set-and-forget, using your fingers and your guitar's volume knob to bring forth a spectrum of organic, blooming guitar tones.
