Ok I have my first gig as a basist coming up in march. It is going to be in a fairly largw room. about 800 people from what i am hearing. I am using a hartke HA7000 wich is 350 watts at 4 ohms times 2. I only have one cab wich is a Carvin 1x18 is this going to be enough without PA support? From what i know the place will probably be packed with at least 800 people and i am concerned about them eating up all of my sound. I am playing with 3 guitarists and they are all running between 50 and 100 watts each. and get a little crank happy on the volume knob and a drumer who is moderately loud. I am saving to get a new bas for thios gig and just realised i may be baetter suited trying to get a 2x10 or 4x10 cab instead.... any suggestions for a 4 ohm cab that can handle around 400 watts or more that is in the 400-1000 dollar price range? or should I get the bass and be fine with my 350 wats into a 1x18?
