From the reviews

I saw, heard and immediately coveted a friend's Chuck Thornton guitar over 20 years ago. I live in Maine so I continued to see them over the years, each was a work of art with innovative design choices advancing the ergonomics, tone and aesthetics of electric guitars.

★★★★★ — Lindsey, Jul 2024

Chuck is amazing, he is the real deal I never knew how involved making a guitar was until visiting, Holysmokes Just selecting the right wood to use Takes some time looking at grain structure and the weigh after that comes cutting and gluing up.

★★★★★ — Giovanni, Aug 2021

I had the pleasure to meet Chuck to fix a minor repair on my Stratocaster. He took the time out to explain his craft to me. He is a master luthier that really has exceptional talents. Before I left I had a hand crafted built guitar. A couple of months later I got the call that the guitar was ready for pickup.

★★★★★ — Frank, May 2026

Seriously? Rate Chuck's guitars? I defy anyone to give them less than 5+ stars! I've seen 'em, I've played 'em. Top to bottom one of the finest instruments you're apt to come across...and friggin gorgeous to boot.
