I hear this kind of argument and often make it myself, but in this case, while the tech inside the amp might, might be truly great, dude that amp has the cool factor of an orthopedic shoe. It's so weirdly plain and forgettable that, knowing Steve, was very likely a conscious choice he made specifically to piss people off so after they complained he could turn around and throw their "shallowness" back in their faces.
And it's extra disappointing because unlike 90% of boutique amps which usually look like new guts put in a classic Plexi headshell format, the old Ultra Lead head was actually one of the meanest looking amps ever made.
People can talk about how only the tone matters, but looks aren't nothing. Cool looking shit can can inspire, lame looking shit can suck inspiration out of the room. IMO the new Ultra Lead does the latter.
Also let's not discount how a lot of guitar players simply don't like analog tube circuits being combined in the same unit with LED screens and digital processing.
