OFFICIALLY LICENSED CIRCUITS RUNOFFGROOVE ENGLISH CHANNEL

From Runoffgroove.com: The Vox AC-30 amp is considered by many to be the defining sound of the British Invasion during the 1960s. The Top Boost circuitry provided crisp treble-laden overdrive that perfectly complemented the rich bass content. The English Channel is a JFET-based distortion stompbox that uses the same basic architecture as that classic early '60s amp. This circuit is based on a 1961 Vox AC-30 with Top Boost, as designed by Tom Jennings and Dick Denney. Artists such as Tom Petty, Brian May, the Rolling Stones, the Beatles and the Shadows have used the AC-30 during their careers.
