Ashdown SO-1200: System Of A Down Levels of Bass! - gearnews.com

gearnews.com

The Ashdown Shavo Odadjian SO-1200 amp head is a powerhouse collaboration, boasting 1200 watts and a 9-band EQ for precision. Ideal for large venues or intimate settings, it features a distinct sonic character shaped by System Of A Down's bassist. Its Variable Valve Drive and One-Knob Compressor enhance tonal control, while the Sub-Harmonic Generator adds depth. Connectivity options are ample, with dual outputs and a DI for PA systems. However, the FS-4 Footswitch, crucial for switching between effects, is sold separately. This amp head scores well for power and versatility but requires some extra investment for full functionality.
