Speedy MACSound
Nashville-raised. Shaped by theater tech chaos. Sharpened by jazz cats twice my age. Putting the Engineer back in Audio Engineering.
Full-Service Audio Engineering
I'm Mason "Speedy Mac" Coverstone—a Nashville-raised audio engineer who grew up in the wings instead of the spotlight. From four-stage student festivals to mixing jazz legends at Blues Alley, I've built a reputation for clarity under pressure.
