Which amplifier do Fontaines D.C. use live?

The Fender '68 Custom Twin Reverb is the main live amplifier identified in the supplied gear information. That makes it the starting point if you’re looking into their stage setup, rather than a complete inventory of every amp they use.

Their sound also draws on offset guitars and complex pedalboards, balancing dissonant riffs with atmospheric textures. The Fontaines D.C. gear article covers that broader picture; the used guitar amps list is relevant if you’re exploring second-hand options, though it doesn’t confirm availability of this particular model.
