How much louder is the Super Flightcase than the standard Flightcase? I picked up a flightcase BG-150 for a good price and it sounded great on a couple of low volume gigs but when I tried it on a louder gig it was basically inaudible. I know it's hard to quantify percieved volume, but is the BG-300 a whole lot louder, or just a little bit louder? Unfortunately nobody local carries the BG-300 to try it out, and I don't want to spend twice as much if it's only a small increase in volume. It's funny how little the wattage ratings mean. My California Blonde amp at 100 watts and 1 12" speaker is significantly louder than the BG-150 at 150 watts and 4 5" speakers. Thanks for any input!
