    Tube Bass pre-amplifier inspired by the Ampeg Portaflex series.

    The Zephyr features:
    -12AX7 preamp tube selected for low noise and good tone, run at 300V B+ (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

    -HPF switch - Passive filter (-6dB/Octave) set at 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 an excellent 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.

    -Heavy gauge aluminum faceplate, all stainless steel hardware
