Aura

AURA doesn't change your tone. It elevates it.

This transparent overdrive is built around a carefully tuned op-amp design that enhances your sound without masking its identity. Your guitar still feels like your guitar — just clearer, deeper, and more harmonically alive.

Inspired by a legendary British drive and its most iconic evolutions, AURA puts a wide tonal spectrum at your fingertips. A dedicated toggle selects between low and high gain modes, while a second toggle activates an additional Class A gain stage. The result is a hybrid architecture that blends soft clipping in the first stage with natural clipping in the second — producing complex harmonics and a smooth, blooming response.

That dimensional bloom — that subtle expansion and shimmer — is the very aura that defines its character.

Alongside the classic Tone control, a dedicated Presence knob refines the upper frequencies, letting you dial in the perfect balance of warmth, articulation, and sparkle with any guitar and amp.

Aura also features the exclusive Nutshell MIDI READY switching system, designed to expand programmability and seamless integration in modern hybrid analog/digital rigs.

Refined. Expressive. Effortlessly musical.
