I am planning on getting a fretted MM sterling in the next 6 months... I would like to get the piezo's for even more tonal options, but I was wondering if it is possible to turn them off or completely mute them with a switch or using the added piezo control/knob on the bass. I'm just curious because if it's a bit too harsh on stage or I'm not feeling it, I'd like to be able to turn them all the way down or 'off', WITHOUT sacrificing tone in other areas or affecting the sound of the other pickups etc... Any knowledge, details or experience with this is greatly appreciated. Thanks! Graham P.S. - My plan is natural body with a maple neck...if that makes a difference to you at all.
