I have recently converted over from keyboard to bass (about 6 months now) I have been playing since the late 60's and back in the day played bass also, I have always been a gear head, so my current rig is a GK 2000RB with two 8ohm Acme B2's. I ran into a deal for a Ampeg SVT-3 Pro but the Acme are not very efficent, and I wanted to get some feedback on this head before making the leap. My rehearsal amp is an Ampeg combo BA-115 that has decent sound, and Ampeg was the lick back in the day. Has anyone ran this head with a pair of Acme B2's? Is there enough headroom with the SVT-3 Pro so I can put the GK on the back burner? By the way although I have been on the boards for a few months this is my first post.
