Apollo Quad Head

Achillies Apollo Quad Head

The Apollo Quad Head delivers the unmistakable feel and authority of a quad-6V6 platform in a compact, flexible head format—designed for players who want full control over their speaker pairing and overall rig response. It retains the same core circuit philosophy as the Apollo Quad Combo, but without a fixed speaker, allowing you to tailor the amp precisely to your needs.

At the heart of the Apollo Quad Head is a four-tube 6V6 power section, supported by uprated power and output transformers capable of handling the increased current and dynamic demand. The result is a tone that feels larger, tighter, and more authoritative than traditional small-format designs, while still maintaining the warmth, harmonic complexity, and touch sensitivity that make 6V6-based amps so musical.

A master volume gives you control over overall output without sacrificing feel, allowing the power section to be pushed at sensible levels. The half-power switch further expands the amp’s flexibility, reconfiguring the output stage for earlier breakup, increased compression, and reduced volume—ideal for studio work, rehearsals, or smaller stages.

As a head, the Apollo Quad truly shines in its ability to adapt to different cabinets and musical contexts. Pair it with an Apollo 2x10 for a balanced, articulate response with fast transient attack, or match it with a Phoenix 4x10 for maximum punch, spread, and stage presence. From compact setups to larger rigs, the Apollo Quad Head responds effortlessly to different speaker configurations.

Tonally, the amp spans rich, detailed cleans through to thick, harmonically saturated overdrive, responding dynamically to picking nuance and guitar volume changes. It also excels as a pedal platform, offering a stable, musical foundation for drive, modulation, and time-based effects.

Handwired with the same meticulous attention to detail found across the Achillies range, the Apollo Quad Head is built for players who want classic feel, modern control, and the freedom to shape their rig exactly as they envision it.
