They reformed a few years ago and are cranking out amps. Mark Sampson is no longer part of the deal, but the designs are still solid and they seemed to have not missed a beat.
My Franklin 15 has a Matchless Lightning 15 as it's father.
My future Franklin 30 will be like the 12AX7 channel of the Matchless DC30.
For old Fender amps that are no longer in production, I can build one for anyone.
Matchless changed hands from #1 owner Mark Sampson to #2 owner Phil Jamison sometime around 1999. There's no difference between them, although the Sampson era have a little bit more collectibility. The new Matchli are F'in amazing. I saw the new Avenger, Phoenix, and Independence models at the LA Amp Show.
Here's a picture of current owner, Phil Jamison at his booth.
