PRS vs Fender: The Stratocaster Shape Battle Escalates — Even the Silver Sky Is Now Under Fire

PRS Guitars has officially confirmed that it received a cease-and-desist letter from Fender, with the dispute centered around the hugely successful Silver Sky signature model developed alongside renowned guitarist John Mayer. The key question now is whether this guitar truly fits Fender’s definition of a Stratocaster copy.

As Fender intensifies its efforts to challenge manufacturers producing Strat-inspired instruments, PRS Guitars has become one of the latest companies drawn into the controversy.

The story traces back to a German copyright ruling issued last year, which recognized the Stratocaster design as a form of “original creative expression.” That decision gave Fender stronger legal footing to pursue infringement claims against Strat-style instruments manufactured, distributed, or sold within Germany and the broader European Union. Many observers viewed the ruling as a catalyst for a more aggressive defense of Fender’s iconic design.

The first company publicly affected was LsL Instruments. In May, the Santa Clarita-based builder received a cease-and-desist notice concerning its Saticoy electric guitar.

Now, according to reporting from The Wall Street Journal, Fender has taken similar action against PRS over the Silver Sky, one of the most commercially successful signature guitars ever produced by the Maryland-based company and developed in partnership with multiple Grammy Award winner John Mayer.

The publication reported:

“PRS Guitars, a company associated with artists such as John Mayer and Carlos Santana, confirmed that it was among the recipients of the letter. The company stated that it disagrees with Fender’s assessment and declined to provide additional comments.”

Since its debut in 2018, the Silver Sky has become one of the standout success stories in the PRS catalog. The model topped Reverb’s best-selling guitar rankings in both 2022 and 2023, slipped to third place in 2024, and climbed back to second place in 2025.

Like many contemporary electric guitars, the Silver Sky clearly draws inspiration from the Stratocaster platform. Given John Mayer’s long-standing connection with Strat-style guitars, this influence comes as no surprise. However, whether the instrument crosses Fender’s legal threshold for imitation remains a matter of debate.

In a statement obtained by Guitar World, Fender clarified that its actions are not aimed at every double-cutaway guitar design. Instead, the company says its focus is on instruments it considers to be particularly close reproductions of the Stratocaster.

According to Fender:

“Our objective is simply to safeguard one of the company’s most iconic and recognizable designs while continuing to support a dynamic and innovative guitar industry.”

The Silver Sky certainly incorporates several features associated with the Strat formula, including a three-single-coil pickup layout, white pickguard, alder body, maple neck, and the option of either rosewood or maple fingerboards. Nevertheless, PRS told The Wall Street Journal that it does not agree with Fender’s interpretation.

That opinion is shared by others within the guitar community.

Speaking recently with British retailer Gear4music, respected Strat enthusiast Philip Sayce, owner of the famous heavily modified 1963 Stratocaster known as “Mother,” argued that the Silver Sky occupies a category of its own, despite becoming an important part of his touring setup.

“Vintage guitars that I’m fortunate enough to own remind me of classic 1960s muscle cars,” Sayce explained. “They have a certain rumble and personality that simply can’t be fully recreated.”

“In contrast, the Silver Sky feels more like a modern electric vehicle equipped with power windows and Wi-Fi.”

He continued:

“For me, each instrument has its own purpose and identity. I don’t see the Silver Sky replacing a truly unique vintage guitar. It certainly contains elements that remind me of instruments I love, but it also has its own voice and character.”

John Mayer has expressed a similar view in the past. During an interview with MusicRadar, he emphasized that the Silver Sky was never intended to replace the Stratocaster.

“This guitar is designed to coexist alongside Fender amplifiers, Fender guitars, Gibson guitars, and virtually any other guitar in the world,” Mayer said.

“It isn’t trying to rewrite history. It simply offers a new path forward.”

Ironically, the overwhelming popularity of the Silver Sky has helped establish it as one of the strongest modern competitors to the Stratocaster. On Reverb’s list of best-selling guitars for 2025, the only model that outsold it was Fender’s own American Professional II Stratocaster.

That competition may reflect PRS’s remarkable success more than any direct imitation. However, with Fender now extending its legal campaign beyond small boutique builders to major industry players, the dispute has evolved into a significant story for the global guitar market.

For now, the outcome remains uncertain. PRS Guitars continues to maintain that it has done nothing wrong, while Fender has demonstrated a willingness to defend the Stratocaster design against manufacturers of every size.
