Digitech Whammy
The Whammy is one of Bellamy's main effects and he uses it a lot in solos. It can be heard when listening to the solos of Sunburn, New Born or the middle 8 of Recess. The WH4 is the reissue pedal, there have been 3 other variations of it, the original WH1 which is still used by guitarists such as Jonny Greenwood of Radiohead.
There was also the XP100 Whammy/Wah and the Bass Whammy which weren't as successful as the WH1 or WH4. Bellamy however owned a XP100 but it was never used live.
One of the strongest points about the WH4 is that it has the ability to be controlled by MIDI. Some of Bellamy's guitars, such as 007 and Bomber have MIDI strips on, and this allows Bellamy to change the pitch on the Whammy by running his finger along the MIDI strip.
Bellamy has 2 Whammys on his current board.
