Im picking up a newer Ampeg 810 cab, and need some head recomendations. I play in a real rocky rockabilly group. I don't slap much, never compete with the guitarist for the higher notes and don't use distorion. I like nice thumpy lows that rattle the heck out of everything! I'm mainly thinking about a Streamliner 900 or Ampeg SVT Pro 3 or 7 at this point. I like that the Ampeg stuff would match but have read some reliablility things about the new Ampegs...Plus half the reviews say the Ampegs are louder than crap and other say that don't have any volume at all for the wattage???????? (We are pretty loud at times!) Actually will i be able to get real good lows out of the newer Ampeg 810 cab? Thanks for the help! PS Also considering the Carvin B2000!
