Mesa/Boogie 400+ Update
I picked up my 400+ from The Amp Hospital today. It looks fabulous, it's all working perfectly, has a full set of chassis screws and just feels great. It's such a lovely thing to look at, handle, use, feel, smell, hear (it whirs, clicks and buzzes).
The conversation covered how these are one of the 3 GOAT Bass Amps, how military spec and robust the 400+ is and that along with the B15 and SVT it's modelled by all the digital effects companies. But most of all that, as long as components are available, these things will last forever. The 400+ is one of my favourite products ever, to me it's up there with the Audi Ur-Quattro or Porsche 959. A lot of products that push the tech to extreme iterations fail, become white elephants but like the 959 and the Ur-Q, the 400+ is an absolute classic and a gem in all respects.
Putting my money where my mouth is, the 400+ will be sitting atop a pair of Monaco cabs at two gigs this weekend. The GKs will be on the bench.
Warm it up and let it rip is what the manual should say 😉.
