Apollo Approved Audio Devices is a boutique guitar effects pedal maker based in Indonesia, founded and operated by a builder known as Agus. Working on a small-batch, direct-to-consumer model — primarily taking orders through Instagram — the brand has built a following among tone enthusiasts for handcrafted overdrive, fuzz, and distortion pedals that draw on classic circuit designs executed with careful, hand-built construction.

The catalog spans a range of circuit inspirations. The Skyscraper is a Blues Breaker-style overdrive and boost that earned notable public praise from Mike Piera, the designer of the Analogman King of Tone. The Buckartie-Boo is a take on the Nobels ODR-1, prized for its mid-forward character and the way it preserves string separation under gain. The Anchor Jubilee is a Tubescreamer-type overdrive built around NOS Japanese JRC4558DD chips, while the Unicorn is a Klon-inspired overdrive and boost. The Steam Roller is a two-transistor germanium fuzz using OC140 transistors, and the Sawdust is a Mostortion-style overdrive with a three-band EQ and a clipping mode toggle.

Because Apollo Approved pedals are produced in limited quantities and sold direct, they frequently surface on the used market through platforms like Reverb, where they draw consistent interest from players seeking boutique-quality handmade effects at prices below the most prominent Western boutique makers.

Apollo Approved has 4 products cataloged on Equipboard, including Overdrive Effects Pedals and Distortion Effects Pedals. Their gear is featured by 3 artists, with the strongest followings in Folk, World, & Country, Rock, and Blues. Notable users include David Grissom, Drew Nix, and Rob McNelley.
