Unlock the full curriculum.
The whole 56-lesson Academy course, the Jam band behind you, the mic that hears you play. No limits on your practice. ThunderFret is built by one guitarist — no investors — and Pro is what keeps it online, growing, and completely ad-free for you.
🐦 Early-bird pricing — locked in while ThunderFret is new. These rates rise as we add features, so grab them while they last.

The tool and the theory are free — Pro is the course. Every plan unlocks the exact same Pro: the Academy's 56-lesson course with its daily assignment and spaced-repetition reviews, Jam mode's backing band, live Play with mic feedback, the multi-track Composer, the 10 Pro practice drills, the Harmony guide, MIDI export and watermark-free images. The only difference is how you pay.
Paid checkout isn't open yet, so the whole of Pro — the Academy course included — is free for a month in the meantime. Leave your email, we'll send a code, and you redeem it from your profile. No card, no obligation: when the month is up you simply go back to the free plan.
The code arrives by email within a minute or two. Checkout opens once the paperwork is done.
