About Form Factor Audio
California-built bass amplification, engineered for tone and obsessed over by the people who play.
Form Factor Audio builds high-performance bass amplifiers, cabinets, and stage gear in California. Every product in the Bass Instinct Series is designed, assembled, and tuned for one purpose: to deliver the cleanest, most powerful low end a bass player can stand behind — night after night, room after room.
Made in California
Our amplifiers and cabinets are built in California, not outsourced. That means we control the quality of every component, every joint, and every final tone check before a product ships. When you buy Form Factor, you're buying gear made by the same people who answer the phone when you call.
The Bass Instinct Series
The Bass Instinct line spans everything a working bassist needs: high-headroom amplifiers, ceramic and lightweight neodymium cabinets, hybrid enclosures, and stage & studio stands. Each model is engineered to pair together as a complete rig, so you get consistent, predictable tone whether you're in a practice room or on a festival stage.
Why players choose Form Factor
- Tone first. Voiced for articulate, full-range bass response with the headroom to stay clean at volume.
- Built to last. Road-ready construction and serviceable design, backed by real support.
- Lighter rigs. Neodymium and hybrid cabinet options cut weight without giving up output.
- Real people. Direct support from the team that designs and builds the gear.
