D’Addario Admits Suno AI Regenerated Promo Track After 2 Weeks of Denials

Q: What hidden audio artifacts finally forced a major guitar brand to confess they faked a product demo with AI?

It was the telltale mismatch artifacts in the audio — especially melody and tempo changes that could not be explained by normal mixing or mastering — that ultimately exposed the demo as AI-regenerated. Viewers noticed the finished promo did not line up with the behind-the-scenes Logic session D’Addario released. The final track contained phrasing, timing and note-contour differences from the stems shown in the DAW, suggesting the audio had been re-rendered rather than simply processed. Critics also pointed to the kind of synthetic “drift” and unnatural transitions often associated with generative tools. Guitarist and YouTuber Rhett Shull’s review strengthened that case. After examining the Logic files, he concluded Suno had likely been used somewhere in the workflow because the discrepancies were too large to come from compression, autotune, export quality, or AI-assisted mastering tools such as LANDR or Logic’s Mastering Assistant. LANDR reportedly also indicated its tools could not create the melody and tempo alterations people were hearing. Those hidden artifacts mattered because they were not just tonal oddities or overproduction. They suggested the underlying performance itself had changed. That distinction undercut D’Addario’s earlier explanations and led to the company’s eventual admission that Suno Studio had been used to regenerate the original track.

D’Addario edited its July 29 Instagram post to admit Suno Studio was used to regenerate the track in a promo video, reversing nearly two weeks of denials.
The company said a full review found it had shared inaccurate information, apologized, and pledged to require employees and creative partners to disclose any generative AI use.
The update also apologized for heavy-handed moderation after critics’ comments were deleted and some users were blocked during the backlash.
Suspicion had grown after D’Addario blamed export quality, Autotune, and mastering tools, then posted Logic session clips that did not match the finished track.
The reversal adds to wider AI tensions in the guitar industry, following earlier controversy over Fender CEO comments likening bandmates to analog AI.
