Abi Guitars is a small-batch luthiery run by Bilge Han Deniz out of a workshop in the Rasimpaşa neighborhood of Kadıköy, Istanbul. The shop builds custom handmade electric guitars and also handles setups, fretwork, nut work, and general repair for local players. Posts from the workshop feature everything from neck carving and fretboard prep to finish work and final sound tests, reflecting a one-person, hands-on build approach rather than a production line.

The lineup centers on custom orders, with recurring in-house designs such as the Model HH appearing in the shop's builds alongside one-off instruments in styles ranging from mini goldtops to offset-inspired bodies. Work is documented heavily on the @abiguitars Instagram and Facebook pages, which double as the shop's primary point of contact for commissions.

Abi Guitars has 1 product cataloged on Equipboard, including Solid Body Electric Guitars.
