As someone who has recently invested in a vintage-style guitar and a vintage amp (or at least, a secondhand one), I’m very much take with these guitar and amplifier pillow cases.
Actually, they’re officially known as Music Lover Pillowcases, and featuring a Fender Stratocaster guitar and am amp I can’t quite identify. Each is made of a nylon and cotton mix and should fit standard-sized pillows.
You can buy them online from US retailer Modcloth, priced at $24.99 (around £13).
