Just saw these unofficial specs on another forum...
4xECC83s in the preamp, 1xECC83 + 4xEL34s in the
power amp, 4 channels with 3 different gain structures per channel (modes), digital reverb with individual controls per channel, dual master volumen, presence and resonance controls, programmable parallel FX with mix control, series FX loop at the end of the preamp, emulated XLR output and JCM800 power and output transformers.
All the modes, fx and master settings can be programmed and made as a preset in the footswitch to switch instantly between sounds or the front panel keys can be mapped into the footswitch so you can control the front panel switches with your foot (for example to switch between the master 1/ 2). Additionally the presets can be recalled via MIDI but with the included footswitch it is more flexible.
All the circuitry including the FX loops and the reverb recovery is valve based, no transistors or integrated circuits at all. Only the reverb circuitry and the speaker emulator are solid state but the reverb is paralell so only the reverb signal goes through that circuit and the speaker emulator obviously is off the signal path.
The footswitch is fully programmable and it is connected to the amp with any standard jack-jack cable, no more multipin or strange connectors here. It also indicates the current amp status so you don't have to look back to see where you are.
