Austin Williams

at the end of this video you can see Austin using a Danelectro.

Austin is unmistakably using the Kurt Cobain Mustang

Can be seen underneath the Rockerverb 50, with the letters 'OZ' taped onto the front.

At the Isle of Wight Festival 2014, Austin Williams is seen playing a Fender Eric Johnson Stratocaster Electric Guitar, as captured in photos on Zimbio.

Austin Williams frequently performs live with a Gibson Les Paul Zoot Suit, as noted in the Evening Standard's review of Swim Deep's NME Awards show at Koko.

In the Gigwise photo, Austin Williams's Orange Rockerverb 50 Mk III Head is identifiable by the "OZ" tape marking on the front of the PPC212 cabinet.

Here, Austin can be seen with a white Fender Jaguar.

Here, Austin can be seen playing an LP Standard. This guitar was used throughout 2012 and the first album tour, before it was 'replaced' with the Zoot Suit, which became Ozzy's guitar of choice.

On top of the Rockerverb is an Orange lunchbox head, I believe this to be a Dual Terror, because of the slightly larger size.

Austin Williams used an Epiphone Les Paul Standard guitar during Swim Deep's early performances, as shown in a user-uploaded photo on Counteract.
