I was wondering if it would cut it or not. For what I am using it for right now I think the II would work. However if I were to add a few more members to the group, especially a drummer. I would be kicking myself for not getting something a little bigger.
They have a used Mustang IV downtown here for a good price. I might take a look at that. Overall size and weight might scare me back to only one speaker but we will see.
