Sweetnrt Tuner
Tune your BFTS guitar. Tune like Eddie Van Halen. Free.
Most tuners ignore intonation theory. In equal temperament, the major third is 14 cents sharp — causing chords to beat under distortion. Dropping the B string 14 cents brings the G–B interval closer to pure intonation. This applies in open tunings too (Open E targets G# instead). The Buzz Feiten Tuning System corrects the same problem at the nut level. Three presets: Standard ET, Just 3rd, BFTS. Guitar, Bass, 12-string, Ukulele. Auto string detection, offline PWA, no login.
Hey Product Hunt! 👋
Sweetener Tuner was built with the help of Claude by Anthropic — from the tuning logic to the UI to this very post.
The Just 3rd preset (inspired by EVH's famous B-string trick) and the Buzz Feiten Tuning System offsets were all researched and implemented through long conversations with Claude. It's genuinely the best AI-assisted dev workflow I've experienced.
Give it a try — especially if you own a Washburn, Suhr, or Tom Anderson! 🎸
