Overview of Callaway Epic GBB:

The Callaway Epic GBB is a driver that was released in 2017. It features a titanium head and a carbon fiber crown, which helps to reduce the weight of the driver. The GBB stands for “Great Big Bertha,” which is a nod to the popular driver of the same name from the 1990s. The Epic GBB also features Callaway’s Jailbreak technology, which is designed to increase ball speed and distance.

Overview of Callaway Epic Flash:

The Callaway Epic Flash was released in 2019 and features a unique face design that Callaway claims is the result of using Artificial Intelligence (AI) to optimize the design. The Flash also features a titanium head and a carbon fiber crown, similar to the GBB. However, the Flash has a slightly smaller profile than the GBB, which some golfers may prefer.


Both the Epic GBB and the Epic Flash are high-quality drivers that are designed to help golfers hit the ball farther and more accurately. However, there are some key differences between the two drivers that may make one more suitable for you than the other.

One of the biggest differences between the GBB and the Flash is the face design. The Flash features a unique face design that is optimized using AI, while the GBB does not. This may result in slightly different ball flight characteristics between the two drivers. Additionally, the Flash has a slightly smaller profile than the GBB, which may make it more appealing to some golfers.

Another difference between the two drivers is the sound they produce. The GBB has a more muted sound, while the Flash has a more pronounced “crack” when you hit the ball. Some golfers may prefer one sound over the other.

Performance comparison:

When it comes to performance, both the Epic GBB and Epic Flash are designed to help golfers maximize their distance off the tee. The Jailbreak technology in the GBB is designed to stiffen the body of the driver, which helps to transfer more energy to the ball at impact. Meanwhile, the unique face design in the Epic Flash is said to create faster ball speeds and greater distance, thanks to the use of AI in its development.

In terms of forgiveness, both drivers are also designed to be forgiving on off-center hits. The GBB has a more traditional shape and center of gravity placement, while the Flash has a more advanced weighting system that is designed to create a more stable, forgiving driver.

Price and Availability:

Both drivers are still available in the market, but the Epic Flash may be slightly easier to find due to its recent release. The Epic GBB was released in 2017 and can still be found in some retail stores and online marketplaces. The Epic Flash was released in 2019 and is still widely available. As for the price, both drivers are in the premium price range, but the Epic Flash tends to be slightly more expensive due to its newer release.
