The Arkham Sound Oracle V1 is a single-channel, vacuum tube pre-amplifier inspired by the iconic Portaflex Bass amps of the 1960s. It features a 12AX7 tube, selected for low noise and good tone, and is powered by a 300VDC power supply. The preamp has a buffered 1/4" output, providing ample gain to feed a modern power amp or the line input of a recording interface.

The Oracle features a pedal-sized enclosure with the full Arkham EQ, allowing for a wide adjustment range with minimal interaction. It has dual Lo-Z outputs, Out 1 for normal use (power amp, interface, etc.) and Out 2 for additional use with a DI box. The controls include Gain, Treble, and Bass.

The Oracle is designed to be a bearer of rich tones, inspired by the Ampeg Portaflex series. It is a handmade instrument amplifier, crafted with attention to detail and a focus on tone.

Oracle v1

Introducing a brand new version of the Oracle - a 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.
