Hi! i have some questions about my rig, so ill start saying that my rig consist in a SWR Grand Prix Pre, a Yamaha MIJ crossover, a Yamaha 500+500 amp, a SWR goliath III JR and a Yamaha 1x18. Both cabs are 8 hms, so im delivering about 350 watts to each. I play a 78`Fender Jazz bass. Im very happy with my tone, but sometimes found the cabs to be a little unbalanced. Since i live in Uruguay, i dont have the chance of buying new gear, and the little i can is ultra expensive. Today i saw in a studio around here someone who had a goliath II and a Son of Bertha. I was thinking i may asking him to trade one of his cabs for one of mine, so ill have a 4x10 and 1x18 OR 2x10 and 1x15. Thr problem i have is that i cant carry the 1x18 to gigs, cause its TOO big and heavy. So any of theses choices would suite me, cause i can move both 2x10 and 1x15 OR use only the 4x10 at gigs. My questions are the following: -do you think the 2x10 and 1x15 will be enough loud to gig in small clubs without P.A? and to rehersal? -do you think the 4x10 will be enough loud? -is it a good trade the SWR Jr for the Goliath II ? -is it a good trade the yamaha 1x18 for the Son of Bertha ? Well, thanks for for any advice, and ANY input is welcomed!!!
