Airtight Cup - Part 1

The more airtight you can get your cup the bigger your sound when playing amplified (more muted, bassy, distorted, louder, etc.). Pic up your harp and mic and make your best, most airtight cup. Now drop the harp on your lap and place your lips where your harp was and blow... where air leaks is where sound is leaking. Work on closing those leaks and your amplified playing will move to the next level.
