I am traveling for a gig and have to provide a list of the gear want rented for me. I usually use a 300-400 watt amp like a Little Mark III or Ampeg SVT-400T with two 15" cabs. I want to be somewhat generic, but also make sure I wind up with something that will serve my needs. I was thinking about just saying: "Bass Amp with 300W or more of power (like MarkBass Little Mark III, Little Mark 800, Fender Rumble 800, or similar) and either two 15" speaker cabinets or an Ampeg SVT 810 or similar" Do you think this will get me a decent set up? Am I giving them enough flexibility?
