I don't see why anyone should expect something new soundwise
the amp is supposedly based on the mods Reinhold did back in the day
some of his main products, like the fish, ecstasy and shiva originated from those same mods
what is "new" about it is that it's simple handwired amp with fewer features, which may actually be a plus to some people (like myself)
I doubt the circuit is MUCH the different than the blue channel of the ecstasy or the strat channel of the fish (which are basically jose-like circuits)
my guess: 3 stages + cathode follower on hot input, plex input skips first stage making it a basic plexi; voicing switch probably uses different coupling caps to control the amount of bass
nothing different from Reinhold already has done on the Ecstasy circuit, technically speaking, and that's exactly what should be expected, not some ground breaking new tonal range
the only new thing I see about it is the eq bypass switch
now THAT should make a considerable difference on how the amp sounds
