excellent
QR Code Link to This Post
Gorgeous mains-powered preamp based on Ampeg B15 circuit. Unique EQ control (Range) that sweeps the frequency where Hi and Low controls operate - see below for more info. Note that this is the original model Oracle that uses 120v mains power (IEC cable included).
Trades considered, though I'm pretty well set. Price is fair and firm.
From the manufacturer: single channel, vacuum tube pre-amplifier inspired by the iconic Portaflex Bass amps of the 1960's. The buffered 1/4" output provides ample gain to feed a modern power amp or the line input of your recording interface. For use as an effect pedal, simply turn down the Master control (all knobs at noon is unity gain). The DI output features a high quality output transformer, with Mu Metal shielding for ultra quiet operation.
The heart of the Oracle is a single 12AX7 tube, selected for low noise and good tone, and fed by a 300VDC power supply.
Specifications:
IN: 1/4" TS, Input Impedance = 1 Meg ohm
GAIN: Up to +32dB at flat EQ settings.
TREBLE, BASS controls use a James Tonestack to provide a wide adjustment range with minimal interaction
RANGE control sweeps tonestack "midpoint" anywhere between 150Hz and 1KHz
HI: Gentle rise from 500Hz to 2kHz, at lower Gain settings
MID: +3dB boost at 250Hz
LO: +6dB boost at 80Hz
HPF: High Pass Filter -6dB/Octave at 90Hz
MASTER: Dial back while boosting gain for more distortion
OUT: 1/4" TS, output impedance = 150 ohm
DI: XLR with Ground Lift (up is lifted). -12dB relative to Out jack.
This pedal is large, heavy, and built like a tank. Sounds absolutely fantastic. Pedal was used only in a smoke-free studio environment; tested just prior to listing.
