Guitar Parts Maker D'Addario Finally Admits Using AI Music in Promo Video

An Explanation That Unraveled After Two Weeks

D'Addario, the instrument company known for guitar strings and parts, has finally admitted that its recent promotional video used the generative AI music tool Suno. The controversy began with an Instagram post on July 29. When viewers pointed out that the playing in the video sounded oddly seamless, the company immediately denied using AI. Over the roughly two weeks that followed, the company's explanations kept changing.

At first, it said the sound had been distorted during a low-quality file export. Then it claimed that stacking multiple plugins, including Autotune, had produced digital artifacts. After that, it insisted it had only used AI-assisted mastering tools from LANDR and Logic. But as listeners accumulated audio analysis evidence, these explanations fell apart one by one.

What the Company Finally Admitted

The company ultimately reversed course by extensively editing the original July 29 post at the center of the controversy. It stated that its earlier denials had been wrong, and that Suno had in fact been used in producing the video. It is not known whether the correction specified exactly where or to what extent Suno was involved. Still, since the company itself revised the original post to issue the correction, one thing has become clear: AI-generated audio was indeed included.

Timeline	Company Response
July 29	Original post published; denied AI use allegations
Following ~2 weeks	Repeated explanations citing low-quality exports, plugin noise, AI mastering tools
Mid-August	Post edited; admitted use of Suno

Why an Instrument Company Tried to Hide AI Music

D'Addario makes playing accessories such as guitar strings, picks, and cables. For a company like this, promotional videos aimed at the musician community serve less as simple advertising and more as a trust-building tool showcasing "real playing skill." Suspicion that AI-generated, rather than human, performance had been mixed into such a video was bound to be received far more sensitively than a marketing controversy in another industry. This interest is likely part of why the company kept denying the claims for nearly two weeks.

How to label and filter generative AI content is already becoming a contentious issue on other platforms in the music industry. On August 11, Spotify announced a policy to attach an "AI Persona" badge to AI-generated artist profiles and exclude them from recommendations by default unless a user follows them. That same day, Together AI unveiled a tool that lets users search and match over 600 AI voices, making voice synthesis easier to use. Amid a trend where the line between AI-generated and human sound is increasingly blurred, the D'Addario case is likely to be remembered as an example showing that the assumption "you can tell just by listening" doesn't actually hold up.

So What Changes From Here

This incident showed that even when a brand denies wrongdoing, listeners' own audio analysis can overturn its claims. Going forward, a pattern may repeat itself in which the public first verifies whether AI-generated music or voiceovers were used in corporate promotional videos, with companies admitting it only afterward. For consumers, this gives one more reason to be skeptical when they encounter suspiciously smooth-sounding performances or voices. For brands, the lesson is that disclosing AI use upfront is likely to be less costly in the long run.
