Got this a few months ago on TB and have been LOVING it with my Bergantino Forte HP. It's been adding a really nice chewy 3D quality to the notes. Recently scooped a Fender Super Bassman 300 though so it's a little redundant for my current setup as I can now use that as my tube pre for home recording. Selling to free up funds for another purchase. It's the non-XLR out version. Has two 1/4" jacks instead for your choice in preferred routing. In "like new condition". $525 SHIPPED Get this one shipped for ~$100 than you'd pay for it new.
Here's what Arkham has to say about it:
12AX7 preamp tube selected for low noise and good tone, run at 300V B+ (not a starved plate design).
Standard version features two 1/4" TS 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 use 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 gives a +3dB boost at 150Hz
Lo switch gives a +6dB boost at 80Hz
HPF switch - Passive filter (-6dB/Octave) set at 100Hz
Master volume, dial back while boosting gain to add some grit
Powder-coated aluminum chassis. 7.39" x 4.70" x 2.06"
