I know I could just buy any old power amp and use a separate preamp, but I was looking for something more instrument oriented, not necessarily a PA/studio amp. Something that could stand on it's own if I didn't feel like using a preamp. I know KMD once made a real basic rack head for bass...those Marshall IBS bass heads seem interesting but I don't know much about them....what else might be out there? Requirements: Size must be exactly 2 rack spaces tall At least 100w minimum 4 & 8 ohm outputs Basic, minimal controls like an old Sunn or Traynor Front inputs Prefer solid state Cheap! No Hartkes!
