Mesa/Boogie's Randal Smith has its place in the Hall of Fame of guitar amplifiers. There's Fender, Marshall and Mesa/Boogie, three strong DNAs. I always had a sweet tooth for the Mesa/Boogie amps; I have a photo of me rocking a blue Custom 22 and a Rev C black panel Dual Recto somewhere with only Morley wah between these two. Popular belief is that Smith copied the SLO100 for his Dual design, but I saw the interview with Mike Soldano, who said it was the Boogie Mark which inspired him to do the Super Lead Overdrive in the first place. I will forever cherish Boogies, it broke my heart when they got sold to Gibson
Vox has a strong lineage, too. Nonetheless, Mesa deserves a place in the pantheon.. Smith's designs have been hugely significant, not the least because they've been available to so many players (unlike custom builders like Dumble or Trainwreck).
Ultimately It Is About Sound And Not Tolex Type...I Am Just Surprised They Would Make A Change To Such An Iconic Amps Cosmetics.
Goodness knows I don't want to defend Gibson. Mesa hasn't always used the black smooth stuff on stock models. Lots of models, including early ones, looked quite different.
All the Mark I amps I've seen have been in the cream colored pebbly stuff. So there's your baseline model that put the brand on the map, though the truly iconic look was that amp with a wooden cabinet and wicker grille. Same with subsequent Marks, it's always been the wood and wicker look in their ads and lots of people love it. Haven't seen anyone complain.
The stock Maverick I owned in the early '00s came in the pebbly tan stuff. The Lone Star and Lone Star Special came with pebbly tolex, and an overall design that was definitely, um, 'inspired by' Matchless.
The Fillmore has always come stock with the pebbly stuff and a Fender look. The California Tweed has been cream colored pebbly stuff, with the Matchless look.
The Tremoverb was introduced in the early '90s with standard black real leather, and I had one. My Blue Angel head and cab came stock in blue tolex.
Depending on the model, the Trans-Atlantic was pebbly black stuff, smooth stuff or the little one with the metal top. Different models have come with different types of face plates, control knobs, what-have-you. Fact is, they've all looked different from each other in significant ways.
In any case, it's not that big a deal. The big deal is that Randall Smith isn't immortal, and at some point he wouldn't be designing amps any more anyhow due to age.
Without him, Mesa is just a brand name. Gibson will recycle existing products, and any innovation will be a thing of the past.
However, I do think it's very likely that Gibson will mismanage Mesa, build products offshore (something that bugs me that PRS has done with some models, not to mention the entire SE line), and do other nasty things. Hell, they even ruined the Mesa website.
I get that business exists to make a profit, and they do what they have to do. It just pisses me off for reasons that probably aren't quite rational.
