You can't go wrong with an Aguilar Tonehammer 350 or 500 and one or 2 Aguilar SL112 cabinets. You will be very happy at home and an awful lot of gigs with one of these cabinets. With the TH 500 and 2-8ohm cabs you will have the option of using one cabinet or two (which brings out all the glory of the full 500 watts). The cabs are light, and the amps remarkably small and light. They will cover every bass you want. I own a TH500 and use an 8ohm DB2-10 cab, and that cabinet is (to me) heavy at 59 lbs.
