Our rule of thumb for chording/chugging on the harmonica is to use holes 1 and 2. Adding hole 3 for a larger sound is just fine as well... all depending on if your surrounding licks use hole 3 (it's a good idea to stay away from hole 3 if your single-note licks that surround the chording use hole 3... so that pitch doesn't get over-used). Stay away from chording on hole 4, this is where the harmonica was build to play melody.
