I'm looking to acquire an SWR bass 350 and an Avatar 2x10 cab. The head puts out 220 into 8ohms and 350 in 4 ohms. Do you think I should go for an 8ohm cab or 4 ohm cab? Do you think 220 watts into one 2x10 will be loud enough or will 350 watts really not be that much louder than 220 watts into the same cab? Right now, I'm playing small gigs with pa support Thanks!
