Hello everybody from svp

[svp]

Hello everybody, I am svp, and I live and play in Atlanta. My credentials are as follows, a Dean Edge 5string, a Les Paul, and a Jazz. SVP PRO, Crest LT1500 powering 2-4x10 cabs, and 2-1x15 cabs. I am going to ask for some help right out of the box. Please tell me what brand tubes will take the noise out of the SVP? I switched out the 4-ax7's that came in it for electro-harmonix and left the so-called Groovetube au-7 in place, unit still noisy.
