Hi I agreee with George about adding later in the mixing...How livley is the room your recording in..Billy Pig sounded pritty great just with the echo of the hall and the response of the croud to his genius!!! Using a batch of mikes is great ...Different mikes give diferent flavers to the mix..Go ahead and try the shure mikes back abit and see how they sound before giving up on them ..I recorded a bango at 10 feet with two shures and it sounded great... Good luck and I'm sure all will work out fine ..The cause is such a good one I'm shore you'l have luck...All the best Guy
