Ashdown Interstellar 600 Bass Amp Head

Created in collaboration with legendary bassist Guy Pratt, the Ashdown Interstellar 600 is a 600-watt powerhouse inspired by his iconic ABM-900 tone — reimagined for the modern player. Handcrafted with Ashdown’s renowned British engineering, this amp head combines the warmth and punch of a tube preamp with the precision and control of a studio-grade EQ section, delivering a sound that’s as versatile as it is inspiring.

At its core lies a 12AX7 valve-driven preamp that infuses your tone with rich harmonic depth and musical overdrive. The 9-band EQ provides complete control — from simple Bass, Middle, and Treble adjustments to fine-tuned frequency shaping across the spectrum. The result: powerful, articulate tone that works for any genre or playing style.

Designed for both stage and studio, the Interstellar 600 includes a tuner output, DI out, FX loop, line input, and output mute for silent tuning. With 600 watts of output power and Ashdown’s legendary reliability, this head handles everything from intimate gigs to full-scale arena performances.

The Interstellar’s custom wood enclosure isn’t just visually striking — it’s acoustically tuned to enhance tone and projection. It can also be rack-mounted with an optional kit for flexible setups. More than an amplifier, the Interstellar 600 is a tribute to Guy Pratt’s 40-year career and a symbol of Ashdown’s commitment to tone and craftsmanship.
