I have a Blue Voodoo 120 head and the tubes are pretty much shot. The amp still sounds good, but the amp is VERY noisy. If you yell into the front it will ring through the speakers pretty bad, which leads me to believe I need new tubes (Oh, they're 5 years old also ). So I was wondering if any of you had any suggestions for the best sounding tubes, or if it even makes a difference. The sound I'm looking for would be very heavily distorted, but relativly noiseless, pretty ballsy, lots of bass and a good amount of midrange. If it helps, my main guitar is some old neck through Charvel with active pickups, a preamp, and a Kahler.
