What is your opinion of this product?
I bought this head about 5 years ago when I joined a local band needing a bass player. I needed something that was reasonably priced and powerful enough to be heard over a guitarist running a Marshall DSL100H into a 4x12" cab. Well, it worked wonderfully. I have been using it in one of two different cabs: a 4x10" Ampeg Classic and an old, 1970's Kustom Tuck and roll 2x15" cab. It has no problem pushing either cab with headroom to spare. I keep an SWR Workingman's head as a spare and I never have to touch it because the Hartke has worked flawlessly. Where the SWR gives me a boomy, low end heavy sound, the Hartke is a punchier, twangier sound. Used through the Ampeg cab I get a sound that's perfect for the stuff we play. (Think Fat Mike's sound in NOFX.) I love this head. I am at a point in my career where I could probably buy something a bit more "high end", but I get everything I need from the Hartke. I give you my no-BS guarantee: it is a great head. You can't go wrong with this one.
