That's why I play a $250 Ibanez with the EMG active upgrade for my outdoor bass through a direct box straight to board. As much as I love the tone of my expensive instruments, at an outdoor gig the people out front don't care/know the difference, so it doesn't matter. And yes, we have the big Beheringer digital board, Crown amps, JBL subs and SLS tops, so our PA is worth more than a Sadowsky bass. So in case rain blows in we all chip in on making sure the PA is secured and covered.My main bass is more expensive than the PA and my amp combined.
Where reasonable players have different priorities in light of different circumstances.
