Does anyone have any experiece with the 'earlier' Marks (1-3)? If so, how do they stack up against the 4?
I like the Mark III and IV i have never played the other ones but they are both awesome
The Mark I was the first Boogie, expensive and a collectors item if it's an original. They were the first to put an extra gain stage in the preamp, based on a Fender design. The Mark IIa, IIb, IIc, are also considered to be classics, while the IIc+ is considered to be one of the best boogies ever made by a lot of people.
