Shavo’s Signature Powerhouse

The Ashdown SO-1200 was created in close collaboration with Shavo Odadjian of System of a Down, designed to capture his unmistakable sound and deliver it at any volume. Hand-crafted in the UK, this amp delivers 1200 watts of total output (600W + 600W), providing enough headroom and authority for the biggest arenas while remaining refined enough for studio sessions.

Advanced Tone Shaping

At the heart of the SO-1200 lies a Variable Valve Drive, powered by a 12AX7 preamp tube, offering everything from crystal-clean tones to saturated, harmonically rich drive. A 9-band EQ provides exceptional tonal flexibility, with pinpoint accuracy across the entire frequency spectrum. Add in Ashdown’s one-knob compressor for smooth dynamics and the legendary Sub-Harmonic Generator for chest-rattling lows, and you’ve got every tool needed to sculpt the perfect bass tone.

Dual Power Sections

The SO-1200 features two independent 600W power sections, each with dedicated outputs. This dual design allows for versatile cabinet pairings, letting you mix and match setups to suit any venue. Whether you’re driving a full stack on a festival stage or running a more compact rig in the studio, the SO-1200 adapts seamlessly. With a minimum load of 4 ohms per side, it guarantees reliable performance at any scale.

Professional Connectivity

Connectivity is a major strength of the SO-1200. With four Jack/Speakon outputs, a balanced DI, line and tuner outputs, and a comprehensive FX loop, it integrates effortlessly into both live and recording environments. The wide frequency response (-3dB @ 17Hz–30kHz) ensures every nuance of your playing is captured, from the deepest lows to articulate highs. Whether it’s front-of-house, in-ear monitoring, or studio recording, this amp has it covered.
