D’Addario has admitted that Suno Studio was used in a promotional video for its guitar strings after initially denying that generative AI had been involved. The controversy has become a striking example of why transparency may matter as much as the technology itself.
One of the world’s best-known guitar accessory companies has found itself at the center of an uncomfortable AI music controversy.
D’Addario has acknowledged that Suno Studio was used to regenerate music featured in a promotional video for its NYXL HD electric guitar strings, reversing previous statements in which the company had denied that generative AI played a role in the track.
The admission came after weeks of scrutiny from guitarists, producers and YouTube creators who noticed that the finished promotional track did not appear to match the recording-session material D’Addario had presented as evidence of human production.
For a company whose products are built around musicians physically playing instruments, the episode quickly became about more than a single advertisement.
It became a question of trust, transparency and what music brands owe the artists who buy their products.
Key Facts

It Started With a Guitar String Demonstration
The controversy began with what should have been an ordinary product video.
D’Addario was promoting its new NYXL HD strings, including products designed for extended-range guitars and lower tunings. Instead of presenting the strings through a relatively raw guitar recording, the company used a highly polished progressive-metal-style production.
Members of the guitar community quickly became suspicious of the audio.
The production sounded unusually processed, and some listeners believed it displayed characteristics commonly associated with generative AI music.
D’Addario initially rejected those claims.
The company said the guitars had been recorded by real musicians, while drums and synthesizers were programmed using MIDI. It acknowledged that the track had been heavily produced with plugins but maintained that it was not AI-generated.
That could have ended the controversy.
Instead, it made it bigger.
The Evidence Raised More Questions
To demonstrate that the track was human-made, D’Addario published material showing the Logic Pro recording session used for the advertisement.
But musicians analyzing the files noticed something problematic.
The melodies, timing and rhythm contained in the session did not appear to fully match the final audio used in the advertisement. Guitar creators argued that the differences went beyond what conventional mixing, mastering or processing would normally create.
Guitarist and YouTuber Rhett Shull later obtained the original Logic files from D’Addario and examined them independently. According to The Verge, his analysis strengthened the suspicion that Suno had probably been involved somewhere in the production process.
The controversy was no longer simply about whether a guitar tone sounded artificial.
It was now about whether the explanation provided by the company accurately represented how the final track had been created.
Audiartist Analysis
Using AI in music is already controversial. Denying its use and later changing the explanation creates a much bigger problem. At that point, the debate stops being about technology and becomes a question of credibility.
D’Addario First Blamed Heavy Production
As criticism intensified, D’Addario gave a more detailed explanation.
The company said the original performance had undergone extensive processing involving compression, Auto-Tune, EQ, distortion, multiple synthesizers and a heavily processed drum track.
It also pointed to AI-assisted production technology such as Logic’s mastering tools and LANDR, while maintaining that generative AI had not created the composition itself.
The argument was essentially that conventional production had pushed a human recording so far that listeners mistook it for AI.
But critics remained unconvinced.
Some of the differences identified in the audio appeared to concern musical elements such as timing and melody rather than simply mastering artifacts or tonal processing. Guitar World reported that LANDR itself joined the discussion to clarify the capabilities of its technology.
The pressure continued.
Then Came the Admission: Suno Studio Was Used
D’Addario eventually reversed its position.
After conducting what it described as a full review, the company acknowledged that Suno Studio had been used to regenerate the original track.
The company said it had previously shared inaccurate information and apologized.
It also stated that it does not support AI-generated music and announced that employees and external creative partners will now be required to disclose generative AI usage in future projects.
D’Addario said it would also review promotional material more closely before publication.
That change in policy is important because it acknowledges a problem that will affect many companies, not just music manufacturers.
A brand may commission work from employees, agencies, freelancers or external producers without fully understanding which generative tools were used during production.
As AI becomes embedded into creative software, simply asking whether something was “made by a person” may no longer provide an adequate answer.
The Comment Moderation Made Things Worse
The controversy was intensified by D’Addario’s handling of criticism on social media.
Users accused the company of deleting comments questioning whether the promotional music involved AI and blocking some accounts.
D’Addario initially said its moderation was intended to protect employees and musicians from harassment. After acknowledging Suno’s involvement, however, it also admitted that its moderation approach had been wrong and said legitimate criticism should not have been erased.
This may prove to be one of the most valuable lessons from the entire episode.
Online criticism can certainly become abusive, and brands have a legitimate responsibility to protect employees from harassment.
But removing legitimate questions can create the appearance that a company is trying to suppress information.
When later evidence confirms part of what those critics were saying, the reputational damage becomes much greater.
Why This Case Is Particularly Awkward for a Guitar Company
The identity of the company makes the controversy unusually symbolic.
D’Addario sells products designed for musicians who physically create sound.
Guitar strings are among the most direct connections between a player’s hands and an instrument. Players obsess over gauge, tension, material, tuning stability, feel and tone.
A demonstration exists specifically to show musicians what those strings can sound like.
If the final audio is partly regenerated by an AI system, an obvious question appears:
What exactly is the customer hearing?
A heavily mixed demonstration is already different from hearing a raw guitar signal. But generative regeneration goes further because the resulting audio may contain musical material that was not produced directly by the instrument being advertised.
That creates a potential conflict between marketing polish and product authenticity.
AI-Assisted and AI-Generated Are Not the Same Thing
The case also reveals how difficult AI terminology has become.
Modern music production software contains many technologies that could broadly be described as artificial intelligence or machine learning.
Automatic mastering, noise removal, pitch correction, source separation and intelligent EQ do not necessarily replace the musician who created the underlying performance.
Generative tools such as Suno are different.
They can create or regenerate musical material itself.
That distinction is central to the D’Addario controversy.
Using AI-assisted mastering on a guitarist’s recording is fundamentally different from asking a generative system to reconstruct part of the music.
For listeners and customers, simply saying “AI was used” is therefore becoming insufficient.
Brands need to explain how it was used.
The Transparency Question
- Was AI used only for mastering or cleanup?
- Did AI modify an existing human performance?
- Did a generative model create new musical material?
- Was the musician aware of the AI processing?
- Was the company commissioning the work aware?
- Was the audience informed before the content was published?
This Is Bigger Than D’Addario
The episode arrives at a moment when AI transparency is rapidly becoming one of the largest issues facing the music business.
Spotify is preparing AI Persona labels. Deezer identifies fully AI-generated tracks. Suno is introducing watermarking and fingerprinting technologies. Rights holders are negotiating agreements specifying when artists, voices and compositions can be used in generative systems.
The same question is now reaching advertising.
Brands increasingly use generative tools because they are fast and inexpensive. But music companies operate in a particularly sensitive environment because their customers are often the very creators worried about being displaced by those technologies.
A guitar company using AI music is therefore different from an unrelated consumer brand doing the same thing.
Its customers have a direct professional and emotional stake in the issue.

Transparency May Become More Important Than Prohibition
D’Addario says it does not support AI-generated music.
But the larger lesson from this controversy may not be that every music company needs to prohibit generative technology.
That position may become increasingly difficult to maintain as AI tools are integrated into standard creative workflows.
The more realistic requirement may be radical transparency.
If AI creates part of a promotional track, disclose it.
If AI only masters a human performance, explain that distinction.
If external producers are involved, require them to document the tools they used.
Trying to conceal or minimize generative AI involvement may create considerably more reputational damage than simply acknowledging it from the beginning.
Musicians Are Becoming Very Good at Detecting AI
Another interesting element of the story is how the controversy unfolded.
It was not an automated AI detector that forced the issue.
It was musicians.
Guitarists noticed inconsistencies in the audio. Producers compared recordings. YouTubers inspected session files. Community members challenged technical explanations.
That demonstrates why music brands should be particularly cautious when making claims about production methods.
The audience is often technically sophisticated.
A company selling professional equipment is communicating with customers who understand recording, signal chains, editing, compression, MIDI, mastering and performance.
Those listeners are unusually capable of noticing when something does not add up.
Conclusion
The D’Addario controversy is not important because a company used Suno in one advertisement.
It is important because of what happened afterwards.
The brand initially denied generative AI involvement. It offered technical explanations. It published session material. Critics continued investigating. Eventually, D’Addario acknowledged that Suno Studio had indeed been used to regenerate the track.
The company has since apologized and promised stronger disclosure requirements.
That is a useful response, but the damage illustrates a broader lesson for the music industry.
Generative AI itself will continue to divide musicians.
But misleading musicians about whether it was used may be even harder for a music brand to defend.
