There are many soundboard clips from 2019 in YouTube (many at Mark Knopfler Official Channel) and, in my ears, the tone is not good at all. Specially on the overdriven guitars. Once Upon A Time sounds bad, Money For Nothing even worse. It gets a little better on clean strat tones and maybe when the Les Paul is not so distorted (Your Latest Trick, for instance). But it is not worthy of MK. And I dont understand the economic side of the Kempers in MK case (I could play with Kempers because I am a nobody with no money and a small car to carry my amp). But not for Mark. After all, he is MK, a wonderful guitar player who also happens to be a tone perfectionist and who also is a millionaire who plays a 300.000 USD Les Paul.
