Every Proper Instrument is handmade in Cranston, Rhode Island.

We source our necks and bodies from the most skilled craftsmen across New England and the United States—supporting small builders while creating a truly exceptional final product.

Our pickups are hand-wound one at a time, either right here in Rhode Island or by our trusted partner in Nebraska. Every set carries its own voice, feel, and character.

The goal is simple: deliver something more inspiring than typical boutique brands—without the inflated price tag.

Every Proper Instrument includes a proprietary QR code that stays with it for life, giving you access to its full story—specs, ownership history, and future updates. We hope this feature brings value to your instrument for years to come.

Standard on Every Build:

  • Nitro-finished neck
  • Hardshell case
  • Proper Passive tone system

The Proper Passive System:

This is where things separate.

At 0, your tone is scooped, clean, and vocal—right in that B.B. King to John Mayer lane. No mud, just clarity and musicality. Something you have to feel to truly appreciate. 
At 10, it opens up into full SRV-style twang, presence, and bite.
Everything in between is fully usable—you’re shaping your sound, not fighting your controls. From Hendrix to Gilmour, It's all in there. 

Simplicity at its finest.
