Trevor de Brauw

"If you’ve seen Pelican live, you associate either a Marshall JCM800 or JCM900 with Trevor, but by way of a Sunn-Rat tonal discovery, he realized he liked a beefier, thicker tone so he’s been auditioning amps for a bit. Currently, his main squeeze is an Ampeg V4."

"Right now I'm using a Marshall JCM-800. It's from the brief period when Marshall was switching production from the JCM-800 to the JCM-900, so although it's basically an 800, it's a two-channel amp, which they only made for a little while. I think the gain is a little bit darker sounding, a bit moodier than either the 900 or the 800."

In the video titled "Pelican live | Freak Valley Festival 2022 | Rockpalast" by WDR Rockpalast on YouTube, Trevor de Brauw is visibly using a Sunn Model T Amplifier Head. The amplifier can be seen in the background, positioned on top of an Orange Quad box, with the "Model T" label clearly visible at 39 minutes in. The dial layout matches that of the original Model T, confirming its identity.
