Arkham Sound Introduces the Abyss Tube Preamp
Maine’s Arkham Sound has expanded their line of tube preamps with the Abyss. Described as a mid-priced addition to their lineup, the preamp features the same core circuit as their Bullet and Zephyr models and can be used standalone or mounted in a rack.
The Abyss centers around a 12AX7 preamp tube, which the company says was selected for good tone and low microphonics. It has an XLR output plus a Mosfet buffered Lo-Z output designed to drive modern solid state power amps and work with recording interfaces. EQ controls include Treble, Bass, and a Range knob that sweeps the tone stack midpoint anywhere between 150Hz and 1kHz. More broad sculpting can be had with Hi, Mid, Lo, and HPF switches.
Arkham crafts the preamp with turret board construction, mil-spec Teflon wire, carling switches, Switchcraft jacks, Belton sockets, and more. It is housed in a power-coated steel 2U, 1/2 rack chassis and weighs in around five pounds.
The Arkham Sound Abyss tube preamp is built to order in Maine with a direct price of $650.
