Arkham Sound - The Zephyr

This preamp is an elegant tube Bass preamplifier inspired by Ampeg’s iconic Portaflex series.

12AX7 preamp tube* selected for good tone and low microphonics, and run at correct voltages (not a starved plate design)
Mosfet buffered Lo-Z output, drives modern solid state power amps or recording interfaces with ease.
Gain, Treble, Bass controls - uses a James Tonestack to provide a wide adjustment range with minimal interaction.
Range control – sweeps the tonestack "midpoint" anywhere between 150Hz and 1KHz
Hi switch – adds a "bright cap" to the circuit to open up the high frequencies a bit.
Mid switch – provides a healthy bump around 250Hz
Lo switch – another healthy bump, this time at 80Hz (without any mud!).
HPF switch - a gentle roll off beginning around 100Hz
Mute switch - sweet silence at the flick of a switch
Low impedance output, with an additional “thru” jack for splitting your Bass signal to another amp.
Balanced DI output, featuring a custom wound Cinemag transformer for full frequency response. Ground lift switch for good measure.
Separate master volumes for preamp out and balanced out. Lets you dial in some grit, and adjust stage volume to the board.
DC referenced heaters, for ultra quiet operation.
Turret board construction, Mil-spec Teflon wire, etc.
Carling switches, Switchcraft jacks, Belton sockets, etc.
Powder-coated steel 1U chassis. Weighs ~8 lb.
Anodized aluminum faceplate, all stainless steel hardware.

Please Note: Arkham Sound builds their preamplifiers to order, which can take some time. Current lead time after order is 4-5 weeks.
