The most common technique used in music recording is for each instrument to have its own mike, which is then recorded on separate track on a multi-track recorder. At the mixing stage, the producer positions each instrument across the stereo field by adjusting the relative left:right volumes using a "pan pot". This means that the left and right channels are always in phase for each instrument, so adding the left and right channels together cannot cause destructive interference.
