Any opinion on the differences between the Meteor and Meteor II amps? I know the Meteor II has the 3 knob reverb and the Meteor had the meters on the back panel to adjust the bias, but that's about it. I don't think the Meteor was made very long before Mark came out with the Meteor II. I know that I could contact Mark and get the whole story, but I'd rather hear from the members here their opinions. Are there any other differences? Tone wise etc.
