Whereas the ES-335 was a semi-hollow guitar (having a hollow body with a solid block of maple running through the center) with standard humbucking pickups, the ES-325 was fully hollow, featured Gibson Firebird mini-humbucking pickups, had only one f-hole, and had a half-moon shaped plastic control plate supporting the electronics (input jack, volume and tone controls, and pickup selector switch), although a small number of models had two f-holes and lacked the control plate.
Trapeze Tailpieces were standard, as on other fully hollow Gibsons.
[1] Kings Of Leon frontman Caleb Followill has used his 1972 Gibson ES-325 regularly since 2002.
He smashed his guitar on stage at the T in the Park festival in 2009, allegedly after being frustrated over a recurring sound problem.
He later asked audience members to return the pieces, which were put together by the Gibson Repair & Restoration department.
