I am a guitar player trying to figure a decent bass rig for small venues, just parties with friends so far but something at bars could happen, I may play bass for a band. So far I like the natural punch of the PBass. On the other hand the Jazz Bass note definition is better and seems to be a versatile instrument but does not seem to be as punchy (maybe I need to work on EQ?). I tried these at rehearsal with a 1x15 combo, nothing is mine. Also I was listening to a speaker shootout the other day and there is no question 15 in speaker has a deeper sound as opposed to 10 in speakers son I was thinking, maybe I should use a 1x15 with a Jazz Bass so it naturally adds punch but on the other hand people say a 1x15 can get muddy some times and I plan to play both clean and distortion so note definition is important to me. Is a 2x10 really able to deliver a punchy sound with Jazz bass? What can make a 15 inch speaker flabby? Maybe enough headroom is needed to avoid what some claim can become muddy/flabby? Am I getting too worried about a problem that won't exist when combining Jazz bass with 2x10? Most bass combos I have found in stores around are 2x10, that is why I get to ask all this.
