Bad Cat Purepath Passive Analog Cab Simulator Load Box

Winner of a NAMM 2026 "Best in Show" Award, PurePath isn't just another load box or IR loader.

It's a fully analog, amplifier-driven speaker simulator with a mechanical reactive load— designed to deliver real amp feel without DSP, menus, or power cables.

For players who want the most realistic direct sound possible, PurePath is a breakthrough.

Purepath requires no power and introduces no DSP.  Your amplifier drives the entire system, interacting with a true mechanical load that responds like a real speaker—dynamic, touch-sensitive, and three-dimensional.

To validate the concept, Bad Cat tested Purepath against real mic’d cabinets, multiple speaker pairings, and every major IR and DSP-based solution on the market.  The results were unmistakable.  Where IRs sounded flat or distant, Purepath sounded immediate and organic.  Where digital systems required menus and presets, Purepath delivered great tone with a few simple switches.  Even when switching between a real cabinet and Purepath into a 12" PA speaker, the room feel never disappeared—because it never left.

For tube amp players who want the most realistic direct sound possible—with zero latency, zero menus, and zero power cables—Purepath is a breakthrough.

Studios. Silent stages. Churches. Home recording.

If you love your tube amp, Purepath finally lets you hear it safely, and at its very best.
