It`s a horrible feeling, sitting there wondering if you could have prevented it in some way and that it could all have gone differently if only...
But, sh*t happens and you just have to make the most of the opportunities coming your way.
Like you said, you must have learned a shed load of stuff about amplifying double basses in a massive band,(something most of us will never experience),and you `ve experimented with a vast amount of equipment.None of this experience will be wasted.
Family time seems a great idea. You can`t do the muso stuff without the support of your family.
Summer is coming and I`m sure you`ll be posting Gig news soon, and buying more stuff you probably don`t need
luck.
