I love Marshall style amps, and frankly, these amps were at the top of the pile when comes to modern interpretations of the really great Marshalls. He really cracked the code of how to get a great overdriven Marshall sound at a reasonable volume, and that's no easy task. What a loss to the guitar community losing another great company. But he had to do what is good for him, and taking care of his health is the right priority. It broke my heart ready his letter. But I wish him the best. If I didn;t already have a great Marshall style amp, his would be the first I would look at, and I think, as others have said, his amps on the used market will really go up in price.
