anyone know if it is just the same circuitry as the 1959 reissue ??
Nope. It has cascaded channels, and no loop (unlike the 1959X and 1987x).
There's a video floating around on Youtube from NAMM of someone jamming on one of these. It sounded pretty damn good (for a crappy camcorder mic), lotsa gain, too. Still no master volume, though, so it'll be loud as all hell.
Meh.
Honestly I would rather go to a Egnator seminar since it would probably be in the same price range (my guess this amp is over 2 grand and an Egnator seminar would probably run me $15-1600).
That way I could just build a marshall clone I actually like and learn a bit about amp guts.
What are cascaded channels?
The two channels (normal and bright) are run into each other in series. In real-world terms, it means it has more gain than a normal Superlead.
