Ristola Instruments is a small luthiery based in Campton, New Hampshire, building handcrafted electric bass guitars. The shop was founded by Brian Ristola, who began building in the late 1990s out of Chris Stambaugh's custom shop before establishing his own workshop. Each instrument is made to order, with an emphasis on exotic tonewoods, neck-through and bolt-on construction, and four-, five-, and six-string configurations.

The brand operates at the boutique end of the bass market, producing low-volume custom builds rather than a fixed production line. Models shown in the shop's galleries include the Redwood, Torino, and Cypress series, offered in both fretted and fretless variants. Ristola also co-runs Fat Bass Tone with luthier Max Kay, a separate company that supplies bass pickups, preamps, and bridges to builders and players.

The brand has a modest following among custom-bass enthusiasts and is regularly discussed in the TalkBass community, where owners post build threads and reviews. Brian Ristola has noted session work with musicians including Ian McDonald, Chris Difford, and Tony Rombola.

Ristola has 1 product cataloged on Equipboard, including Electric Basses.
