I've been using my Hartke 7000 lately and I really like the tone and way it cuts through the mix with my loud classic rock band. I never have to turn the volume past 3. The Hartke makes my old ampeg rig that I just sold sound like it had a blanket covering the speakers. The problem is I got it used in a trade and now I'm having problems with one of the power amps distorting and cutting out. I've had it in to an amp repairman who really knows his stuff (twice) and he hasn't been able to find the problem and correct it. Keep in mind I got it used so I really don't know it's history. it could have been dropped down a flight of stairs for all I know. Since I just sold the last of my heavy ampeg cabs I am now in the position to buy a new amp head. I want a solid state head with dual power amps 350x2. Here is what I am considering as options w/ pros and cons(as I see them) Hartke 7000 $675 Pros: I love the sound straight out of the box. Hardly touch the tone controls Cons: Only 1 year warranty, made in Korea, I've heard they have reliability problems(maybe what I'm experiencing now?) Not sure who I would contact for warranty or repair issues. Carvin R1000 $660 Pros: Made in USA, Can call Carvin anytime and get a real person on the phone. I've owned other Carvin equipment (speakers ) and have been happy with them, good bang for buck. Cons: Only 1 year warranty, I've never played one of thier bass amps and am not sure if I can get that same growly,aggressive tone that I get with the Hartke (people that have played both Hartke and Carvin chime in here) Ampeg B4r $950 Pros: Ampeg is very reliable, 5 year warranty, I live 90 miles from factory, I work in the same town with Ampeg dealer that is also an excellent repairman. I could probably trade in my hartke at my local Ampeg dealer and bring the price down some. Cons: I don't think the Ampeg tone is what I want for my band (but I should be able to get any tone I want out of an Ampeg right ?) Other: Make it good and convincing and $1000 or less Here is what I'm NOT going to buy. Anything over $1000 Eden,SWR, Mesa, or Anything with a bunch of tubes. A tube pre amp and a SS power amp. Thanks for reading through all this. And now time for your suggestions.
