Dramastic Audio is a boutique American manufacturer of analog studio outboard, founded by designer John Ellis. The company built its reputation on the Obsidian, a feed-forward VCA stereo bus compressor with transformer-balanced I/O developed in collaboration with Jensen Transformers, an internal high-pass side-chain filter, and stepped controls for precise recall. The Obsidian was released in the mid-2000s and is hand-built in the USA in limited quantities for recording, mixing, and mastering engineers.

The line expanded with the Obsidian 500, a 500-series stereo bus compressor, along with a dual-mono expansion module that pairs with it for multi-channel use. Dramastic Audio also offers an automation solution aimed at SSL consoles. The gear is sold through professional audio dealers such as Vintage King, KMR Audio, Front End Audio, and Pro Audio Design rather than through mass retail.

Within the pro-audio community, the brand is associated with a punchy, wide-imaging take on the classic console-style bus compressor, often cited as an alternative to vintage SSL bus compression that preserves stereo width and low-end weight. Engineer Alan Moulder has been documented using the Obsidian during mix work at London's Assault & Battery studios.

Dramastic Audio has 3 products cataloged on Equipboard, including Effects Processors. Their gear is featured by 6 artists, with the strongest followings in Electronic, Rock, and Orchestra. Notable users include Alessandro Cortini, Richard Devine, and Sascha Dikiciyan.
