Why we’re better… and why it really matters.

There are a bunch of string companies out there… but we’re different.

Experience matters… and we’ve got a boatload.

Not just any old yahoo can make great strings.


Your strings shouldn’t be corroding

The proprietary technology we use in every package protects your strings.


We love artists… and they love us back – over and over.

When they find us, they stick with us. More every day.
