I just purchased the combo Ampeg SVT Tube Head and the Ampeg 8x10 Cab. I have a question. The guitar player that sold the rig to me said that it is actually better for both the speakers and the tubes if i sat the amp head on floor-stand it came with instead of on top of the 8-10s when actively playing. When playing, his logic was that the speakers bring so much grawl and boom that the tubes might be affected over time. Also the tubes in the amp get so hot that could possibly affect the speakers in the cab. This makes sense, however it might not be true at all. Can a bass gear head who knows this ampeg combo answer this for me? I try to look it up but it is always just sites selling the amps. Multiple answers would be great to hear other opinions or facts.
