ThroBak Electronics is a boutique guitar pickup and effects maker based in Grand Rapids, Michigan, founded in 2002 by Jon Gundry. The company specializes in vintage-accurate reproductions of Gibson's late-1950s P.A.F. humbuckers and P-90 single coils, building pickups with period-correct materials and original-era winding machines — two of which were sourced directly from Gibson's old Kalamazoo factory just down the road from ThroBak's shop.

The pickup line includes models such as the SLE-101 MXV, KZ-115 MXV, ESG-102B, ER-Custom and the '57 SteelHead, alongside Telecaster and Stratocaster reproductions. Beyond pickups, ThroBak produces aged hardware (Kluson-style tuners, ABR-1 bridges, stop tailpieces, pickup covers), guitar strings, and a small line of vintage-style effect pedals including the Stone Bender fuzz, Overdrive Boost and Fuzz Haze.

All products are manufactured in the USA. ThroBak is sold direct through the company's website and through dealers including Chicago Music Exchange, Vintage King and Reverb, and the brand is associated with the broader boutique movement of builders chasing the tonal character of original PAF-equipped Les Pauls and ES-335s.

ThrōBak has 8 products cataloged on Equipboard, including Electric Guitar Pickups, Fuzz Effects Pedals, and Overdrive Effects Pedals. Their gear is featured by 7 artists, with the strongest followings in Rock, Pop, and Jazz. Notable users include Eddie Martinez, Billie Joe Armstrong, and Efrim Menuck.
