Anyone know, from a physics/acoustical engineering perspective, what the best place on the bass would be for a microphone? I see photos that indicate four places that seem to be favoured: - between the legs of the bridge - somewhere near the upper f-hole on the treble side - slightly under the treble side bridge foot. - near the end of the fingerboard I have tried all of these locations on my ply bass. Neither one seems to stand out. But if I knew from a purely technical point of view which would the best, I could spend more time experimenting with a mic in that specific area. I am leaving the type of mic, and that I go straight into the PA through a tube preamp, out of this query to avoid further confusion for myself. Has anyone seen a graph or sound wave dispersal chart of a bass top that would show where the strongest vibration is? Is it close to the sound post? Between the bass bar and the soundpost? Under a bridge foot? Near an f-hole? Is the strongest point of top vibration always the best place to mic a double bass? Would a ply bass react differently to a carved top and be more difficult to mic? Or does any of this really matter...and should I go back to stuffing my SM58 under the tailpiece?
