If your picky about sound, like lot of volume and not always sure you want to carry alot (over 50lbs each) then here are some suggested shopping guidelines: 1. Save your money and buy top of the line "pro" equipment from whatever company you decide. I'd suggest SWR, Aguilar , Eden, EA, ampeg, yamaha (amps). 2. Get at LEAST 300 watts into 4ohms, sometimes I wish I had more, but by swr bass 350 CAN give you an ear-ache in smaller rooms if you want an ear-ache. 4. what about EFFECTS? come on your a bass player! <grin> o.k., maybe a compressor to even out slap bass style or sustain your notes. Maybe a chorus if you like. 4. for portability I'd suggest 210 cabs or 112 cabs. my guidline is nothing over 50Lbs each. it may look and sound REALLY cool to have a 8x10 or 4x12, but as you get older do you really want to be carrying that much weight?? with a luggage cart I can carry my two 112 cabs, rack and guitar into a gig in ONE TRIP. If your always complaining about price, you'll be complaining about your sound too because you will probably spend too little and get CRAP! Bass takes MORE power, Bigger magnets and Bigger speakers than guitar, so expect to spend more on a good bass rig! My current rig cost me $2830 (amp, rack, 2cabs, RBI, Guitar). IN THE LONG RUN I'VE SPENT MORE MONEY TRYING TO SAVE MONEY. everytime I 'upgrade' I lost money somewhere in depreciation, trade-in low-balling, etc. I've spent approximately $6,000 to get to the $2830 rig and sound I have now and I feel ALMOST satisfied. ouch! BUY PIECES unless you are SURE you only want a combo. Or have multiple rigs: Home practice combo, small rig (maybe large combo), medium (head, cab or two), big rig (pre,amp,medium and large cabs). BUY TOP OF THE LINE, MOST WATTS INTO 4OHMS, AND BE WILLING TO CARRY THE HEAVIEST PIECES YOURSELF!! any other good advice out there??
