A friend of mine is offering to sell me his Hartke Transport cabinet and preamp. As of now I have a Crate BX100 amp (in other words, I need better sound equipment), and I am considering buying it. But I know very little about Hartke and even less about this particular amp. So I would like to hear any thoughts or comments you guys have on the Hartke Transporter Cabinet/Preamp. Mostly I want to know about its sound quality/range and its durability. I have heard that it is a bit punchy because the cabinet cone is metallic, but I'd rather hear what you fellow bassists have to say. Any information at all is greatly appreciated. Thanks.
