Geddy Lee uses the Orange 8x10 Cabinet, as confirmed by Richard Chycki in the recording of Rush's 'Caravan'. Chycki stated, "The fourth and last channel is what we call the ‘stun channel’. This is an Orange AD200 MKIII 200‑Watt bass head that’s cranked to the hilt and going through an 8x10 cabinet. This is miked up with a Sennheiser 421, through a Neve 1073 and into the other side of the Fairchild 670." This information was provided by Sound On Sound.
