Here is the new proposed face plate. Slash wanted it silver with silver knobs. Probably because he liked the silver jubilees so much.
and the final prototype in use during sound check
and during the show that night
Apparently they're still fine-tuning the circuit, according to Slash's FB and Twitter feeds today...
Power control!!!!!!!!!!!1
An additional task was to program the amplifier control firmware. We haven’t disclosed it yet but this amplifier features an auto-biasing function which works together with the output power control. We’ve been working on it for more than a year now as it may well appear in some other projects, but we have decided to include it in this amplifier as well. The power control allows the user to obtain power amp distortion at volumes as low as 0.1W going to full 100W with the simple twist of a knob. With a trimmer pot located on the rear panel, the player selects the desired biasing current. When triggered by the user, the amplifier performs a complete biasing job by itself. This feature can be seen as having a little man inside the amp rotating the bias pots and measuring the current for us. Lets highlight too that the biasing is not only limited to the full power control but is performed in all the power range ensuring proper operating conditions at every output power setting.
Looks cool, and the auto-bias/power control will be a killer function if it works...
Gawd...even Marshalls are becoming computerized these days.
New demo. Thoughts?
Check out the power scaling when he dials it down.
Check and see on youtube: is there any videos talking about how SHIT these handwired-series pots are? Those undesireably cheap transformers.. the shit tubes that die out after 6 mos?
That's really a highly sought-after feature, there's a few companies working on this issue so they can justify selling a 2000 dollar tube amp to sound good at the microwatt levels of a 59 dollar Pod piece.
I don't think this is a waste of time at all. Somebody's soon to get a good handle on it, and when they do that's going to be the amp to have.
What a dream: to own just ONE amp you could do bedroom-levels recording with at night, and then do your weekend-warrior thang with the guys. I hope somebody gets this feature right..
