Matthew Bellamy used the Roland VG-8EX V-Guitar System during the Showbiz era, as detailed on MuseWiki's "Guitar effects & Amplifiers" page.

Matthew Bellamy used the Line 6 POD 2.0 Guitar Multi Effects Processor for a distorted direct input guitar sound during the Showbiz and Origin of Symmetry tours. This is supported by an Instagram post by mattbellamygear, which highlights its use for both guitar and vocal distortion on these tours. The post provides an audio example from the Hullabaloo recording, emphasizing that the distorted sounds came solely from the POD, with no Marshall amp on that track. The setup included a four-button Line 6 footswitch for control, commonly seen during performances from this era.
