ThisSo, what the other tube amp companies did in the field of innovation the last 20 years? the only thing i can think is the inclusion of IR technology into the amps. But this already existed outside of them and even if it's great i can't see it as an "innovation".
Something else? I'm asking because maybe i'm missing something.
Guitarists don't want innovation on the tube amp front, they want the same old thing over and over again.
Fender and Marshall just rehash their 60s circuits over and over again and remain the top brands in terms of mindshare. Others? Everything is always their take on a Marshall, Vox or Fender circuit.
Mesa actually has some of the more recent classics with the Mark and the Dual Rec. Yes, the Dual Rec shares a lot with the SLO100, but let's be honest they don't sound like a SLO. Taking negative feedback out and thus creating the "Modern" sound was one of the rare new sounds to come out in the last 30 years.
And no matter what amp is being used, everyone in the metal community loves those Mesa cabinets. Let's pray they never stop making them.
