Mesa Mark IV A or B version?

[WickerBoogie]

Hello!

Im buying Mesa Mark IV and have to ask a couple questions:

Whats the difference between the A and B? Is the B version modern and has a little more gain?

There is a great summary of the A and B versions in the "Mark IV thread" you will find in the Mark Series subfolder of this Folder. So, if you start at the Vintage Amps folder page, at the top of the page is a subfolder called Mark Series. Click on that. The first thread there is called Mark IV thread. The first post tells you exactly what you want to know.
