I've been reading more and more reviews of the ampeg svppro preamp saying that it hisses and is noisy, does anyone have any experience with this and know how to control it? the reason I'm wanting to get this preamp is b/c ive played a svt3pro and liked the way it sounded. there is not many music stores around me that carry good quality equipment so i either have to buy blindly, go with what other people say or what i have played when im out of town... If this is a true problem of the svppro then does anyone have other suggestions of preamps for the same price range? i play in a rock band, we have harder songs and softer songs and i basically want a good all around tone preamp. hope you can help me out.
