Used for Albarn's vocals on Gorillaz's "Clint Eastwood", as mentioned by producer Tom Girling in the September 2001 Sound on Sound article "Recording 'Clint Eastwood'".

We used the Neumann TLM170 for Damon's vocal, and we hired some gear when we went to Jamaica, so I think he probably went through an 1176 as well, or perhaps a Distressor," explains Tom. "We used a Neve 1073, which is an EQ with a mic amp on as well, so the mic was plugged straight into that, and then after that I think it was the 1176 and straight into Logic."

On 'Clint Eastwood', a harmony part was also created from the lead vocal using a Boss Voice Transformer. "It's just a harmonised copy of Damon's main vocal," explains Tom. "For each chorus bit, there is a bit of that underneath the main chorus vocal."

Other vocal effects were also added at the mix: "We've got the rap, we've got reverse reverb on the rap as well, and some delay stuff that we did manually when we were comping the vocal and the melodica stuff," says Tom. "I think it's only the album version that you can hear all this stuff on, though. It's just a delay that's fed back on itself and EQ'd while it's coming back."

"We were just trying to get that tape effect from the digital delay," explains [producer] Jason [Cox].
