I really dig that vintage 60's-70's tone but what gets me is there all like 2x15 and 1x18 (Jack Bruce, Jaco). I really don't like 15's the balance seems to be off not enough highs for the lows you get, don't even get me started on 18's. I know Jaco used a folded acoustic cab and he projected really well nice highs same with John Paul Jones. Did these cabs have tweeters or horns in them? Is it something to do with the P.A's they used? I have a friend who builds cabs (For P.A's) but at the moment he's got 4 folded 18 cabs and he built each for no more than $200 is it worth getting one of these for that old skool speaker sound he also has a 2x15 with horn which he built for like $250, or do I get like a 4x10 which moves more air but is tighter sounding. Would Jaco still be playing through a acoustic 360 with 361 cab if he were alive today?
