I have a wizzy and a clarus 300. I have a chance to buy a ampeg pb112. I am salivating at how light this rig would be. My clarus runs 2 ohms at 300w and both cabs are 4 ohms so i will get the full power from the clarus. So will the ampeg pb 112 + wizzy powered by the clarus be loud enough for my 4 piece classic rock band in up to medium sized venues?
