Shavo Odadjian Signature 1200W Bass Head – Handcrafted in the UK

The Ashdown SO-1200 is a professional 1200-watt bass amplifier head designed in collaboration with Shavo Odadjian of System of a Down. Delivering dual 600-watt power sections, a 9-band EQ with footswitch control, variable valve drive with a 12AX7 preamp tube, and handcrafted UK construction, this Artist Series head provides the massive low-end power, tonal flexibility, and sonic aggression that modern bass players demand. Whether you're playing arena stages, studio sessions, or rehearsal spaces, the SO-1200 delivers professional-grade tone with the reliability and build quality that defines Ashdown's heritage.

1200 Watts of Pure Bass Power

The SO-1200's dual 600-watt power sections deliver 1200 watts of total output, providing massive headroom and punch for any performance environment. The four Jack/Speakon outputs allow flexible cabinet configurations, while the balanced DI output ensures clean signal to FOH systems and recording interfaces. Whether you're driving a single 8x10 cabinet or multiple 4x10 stacks, the SO-1200 provides the power and clarity to cut through any mix with authority.

9-Band EQ & Tonal Flexibility

The 9-band EQ with footswitch control provides precise tonal shaping across the entire frequency spectrum. Dial in everything from deep sub-bass to cutting high-end presence, with the ability to switch EQ settings on the fly via footswitch. The variable valve drive circuit with 12AX7 tube adds warmth and harmonic richness, while the one-knob compressor provides dynamic control without complexity. The sub-harmonic generator adds earth-shaking low-end extension for modern bass tones that demand maximum impact.

Handcrafted in the UK with Ashdown's legendary attention to detail, the SO-1200 features professional-grade components and road-ready construction.
