Hand built in Ashdown's UK Custom Shop, the 22 Head was designed around Shavo Odadjian's desires. Shavo Odadjian is a multi award winning musician, songwriter and entrepreneur. He is best known as the bassist of System of a Down, but the guys at Ashdown know Shavo as family.

The relationship between Ashdown and Shavo began way back in 2002 and Shavo has been using Ashdown’s ABM range ever since. Sharing his gratitude for being a part of the Ashdown family, Shavo said: "I was hooked by their personalities, they were like family... then they showed me their amps and they completely blew me away. The fact that there's a solid-state volume and a tube volume on the same amplifier was amazing and I hadn't seen that before. I'm honoured to be a part of a family company that is not just a 'run-of the mill' and I legitimately represent the company." Shavo has since gone on to be a huge ambassador of Meters Headphones, sister company of Ashdown Engineering.

Paying close attention to Shavo’s appreciation for ABM heads, the Ashdown Artist Edition 22 Head had to be built on the solid foundations of the ABM 600 EVO IV, featuring a 600 watt power section, 12AX7 powered valve preamp, one-knob compression, sub harmonic generator and 9-band EQ.

Shavo was drawn to the looks of the Geezer Butler Head of Doom after being there in person on its US debut at NAMM 2018, so it was clear that the 22 Head deserved the same dual VU functionality and bold visual presence.

Why 22? Shavo has a close connection to the number 22. We was born on 22nd April, got married 22nd May, System of a Down started when he was the age of 22 and System fans would recognise that he’s often worn a 22 jersey on stage. It’s just his thing.

The 22 Head features a sophisticated 9-band EQ with familiar Bass, Middle and Treble controls and six sliders providing precision cut and boost at 100Hz, 180Hz, 340Hz, 1.3KHz, 2.6KHz and 5KHz. The EQ can be switched in via footswitch providing a huge range of tonal variation and the tailoring of the perfect tone.

The 22 Head features a sophisticated 9-band EQ with familiar Bass, Middle Once heard – never forgotten. The ‘One Knob’ ABM Sub-Harmonic generator adds an octave below the notes being played bringing fullness to any bass part. The Sub level is independently controllable, and also footswitchable.

The 22 Head features a tuner output, line out, transparent FX loop and a line input for the connection of an external sampler or sound source. Output muting cuts the signal from the DI output but leaves the tuner output ‘live’, allowing the player to tune up in silence.

The FS-4 footswitch (not included) allows for on-the-fly tonal gearshifts. With footswitchable Valve Drive, Compression, EQ and Sub Harmonic Generator, the FS-4 puts dozens of sound combinations at your feet.
