Arkham Sound Beast of Both Worlds 2019

Hybrid bass amp mating a heavenly vacuum tube front end with a thunderous 1,200-watt ICE module.  These are hand built in Maine in small batches.  This is by far the nicest amp I've ever owned, and I'm only letting it go because I have switched to the pedal version of the preamp, since I do everything through my pedal board anyway.

And I'm happy to answer any other questions you may have.  More details below: 

- Class D power section delivers 1200W into 4 ohms, 600W into 8 ohms.

- 12AX7 preamp tube selected for low noise and good tone, and powered with a dedicated 300V supply (not a starved plate design)

- -6dB input pad

- 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
