— HIGHLINE™ —
Stand inside of your tone.

Traditional guitar amplifiers were designed for the room. Highline was designed for the player.

By elevating the sound field upward into the space where musicians actually hear, react, and perform, Highline restores a more direct connection between player, amplifier, and environment.

The result is not simply greater projection, but greater awareness, control, dimensionality, and immersion throughout the entire playing experience.

— WHY HIGHLINE EXISTS —
Built around the player—not just the room.

Traditional amplifier systems project sound outward into the room, often leaving the player standing below or outside of the primary sound field.

As volume increases, musicians frequently compensate by turning up further—searching for clarity, articulation, and connection that may never fully arrive at their position on stage.

Highline changes that relationship by elevating the listening experience upward into the space where players actually hear, react, and perform—creating a more immediate and immersive connection between the musician and the amplifier itself.

— WHAT PLAYERS FEEL —
More awareness. Less fighting the room.

Players do not typically describe Highline as louder. They describe it as clearer, more immediate, and more connected to the way they actually perform.

Because the sound field is elevated closer to the player’s natural listening position, harmonic detail, articulation, and dynamic behavior arrive earlier and with greater focus—often reducing the need for excessive stage volume in the first place.

The result is a playing experience that feels more immersive, more controlled, and more physically integrated with the amplifier itself.

Less guesswork. Less fatigue. Greater awareness of touch, response, and musical interaction throughout the room.

— HIGHLINE CONFIGURATIONS —
Different formats.
Different physical experiences.
Highline 310

Fast response. Broad projection. Immediate articulation.

Designed for players seeking tighter transient control, enhanced clarity, and a highly focused stage experience with exceptional articulation and speed.

Highline 10/15

Dimensional bloom. Harmonic depth. Expanded physicality.

Combining the immediacy of a 10-inch speaker with the weight and dimensional spread of a 15-inch driver creates a uniquely immersive and harmonically layered playing experience.

Highline 212

Balanced authority. Wider footprint. Full-range impact.

Built for broader room interaction and greater low-frequency extension while maintaining the elevated listening experience that defines the Highline platform.

— HIGHLINE IN ACTION —
See the system from the player’s position.

Highline is not simply a visual design concept. It is a physical rethinking of how guitar amplifiers interact with musicians on stage, in rehearsal spaces, and in real-world performance environments.

By elevating the listening field closer to the player’s natural position, Highline creates a more immediate relationship between touch, response, articulation, and room interaction.

This Premier Guitar feature offers a closer look into the philosophy, architecture, and real-world experience behind the Highline platform.

— CURRENT HIGHLINE PLATFORMS —
Choose the amplifier. Choose the experience.

Highline currently extends the Aurora 35 and Lyra amplifier platforms, each available in multiple elevated configurations.

Aurora 35 Highline

American openness and dimensional response with elevated player immersion.

310  •  10/15  •  212


Explore Aurora Highline

Lyra Highline

Dual American voices with expanded spatial awareness and stage interaction.

310  •  10/15  •  212


Explore Lyra Highline

A different relationship between player and amplifier.

Highline is an extension of the 3rd Power belief that the physical relationship between the player, the amplifier, and the room matters just as much as the circuit itself. Explore the current Highline platforms or experience the system in person.
