Andrew's Harmonicas

Custom Harmonicas:
I customize diatonic harmonicas to connect deeply with the player. Each instrument is remarkably responsive, has amazing tone and tuning, and is adjusted to your playing style.
My harmonicas are loud. They've got fat tone. They allow effortless bending of notes.

Custom Harmonica Combs:
Darken your harmonica with one of my combs. My Dark combs™ are measurably better than factory-made combs. They are made from environmentally-responsible materials. They are beautiful, durable, airtight, waterproof and comfortable to play.

Harmonica tools and customization instruction:
Getting your harmonica to perform best is meticulous work. I offer a complete set of innovative tools. I offer learning products that help you tackle the learning curve of upgrading and customizing your harmonica.
After years of work, I'm still excited about the process! I'm learning new things all the time. I update my tools and learning materials continuously.
