Shiver Guitars is an Italian luthier brand based in Foligno, Umbria, building handcrafted electric guitars and basses. Founded by luthier Cristiano Toni, the shop centers its work on careful wood selection (in collaboration with Rumorelegno) and custom pickup design developed in tandem with Celentano Pickups, whose "Heart of Stone" line is voiced specifically for the brand's instruments.

The lineup includes original designs alongside takes on classic body shapes, with models such as the F Guitar, K Guitar, Antecaster, Tile Guitar, Dead Angel, and the Vintage Color series, plus a bass model simply called The Bass. Alongside new builds, the workshop offers repairs and sells accessories through its own shop.

The brand has built its reputation within the Italian boutique guitar scene, exhibiting at events like the Italian Guitar Show and working with Italian artists — including Dodi Battaglia of the rock band Pooh, who has been associated with the brand as an endorser.

Shiver Guitars has 1 product cataloged on Equipboard, including Ukuleles.
