    South Portland, ME - BEHOLD -- THE ORACLE !

    "a bearer of rich tones, featuring the full Arkham EQ in a pedal sized enclosure"

    The Oracle features:

    - 12AX7 preamp tube selected for low noise and good tone, run at 300V B+ (not a starved plate design)

    - Dual Lo-Z outputs, Out 1 for normal use (power amp, interface, etc.). Out 2 may be used additionally to feed a DI box.

    - 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 - moves -3dB point from 30Hz to 100Hz. It's a gentle roll-off(-6dB/octave), used in conjunction with the Bass control and boost switches to shape your low-end tone.

    - Master volume, dial back while boosting gain to add some grit

    - Powder-coated aluminum chassis. 7.39" x 4.70" x 2.06".

    - Export and dual voltage versions available.

    $550 + shipping. Current build time is 2 to 3 weeks.

    Interesting...No XLR out but a 1/4 line out for one.

    I like the control interface. I like how it seems no nonsense streamlined, yet tweaker delight at the same time. All the right stuff and no wasted fluff, idk?

    Either way looks nice.

    I am wondering the same thing, the Noble has it. A portable tube pre is a great thing for traveling bassist why not adding an XLR?
    also what is the weight?

    The link goes to the explanation. Makes a ton of sense, I would rather it be quiet than cost a ton more with potential noise floor increase.

    I could care less about a tube pedal preamp having an XLR. Use a REDDI so that's covered.

    I watched the video. That's somebody's dream tone, but not mine. Warm, wooly, and...not a hint of articulation.

    I found 2 Arkham videos on YouTube. Based on the 1st one I watched, I totally agree with you. But this one changed my mind:

    That's certainly closer to the tone in my head. I've bought quite a number of things online based on videos, and what I get doesn't always relate to what I heard - too many variables, probably.

    Paul Nowinski's endorsement means a lot to me. This guy's a pro's pro. He did NOT just fall off the turnip truck.

    Think Ampeg B-15. This one has the same controls as my older Arkham Abyss, that I still use and love. Based on that experience: if you look for an actual tube tone (as opposed to an approximation of tube-based distortion), this is it.

    I'm not seeing what the output spec is? Anyone know or did I miss it?

    Looks interesting. Kind of like a poor man's Noble pre. Not that 550 isn't a lot of scratch.

    Which spec? Gain is approximately 31dB, output Z is 150 ohms.

    I meant gain, sorry. Reply appreciated, may well take the plunge.

    I received mine this week. Though I haven't had a lot of time with it yet, first impressions are favorable.

    Did you see @kringle77 videos in the Zephyr thread? I relate much more to his tone than to the videos on the Arkham YouTube channel, personally.
