GBB Epic Driver
Epic Distance for Every Player
GBB Epic is so-named because it represents an epic shift in how the head and face behave to enhance power, spearheaded by Callaway’s innovative Jailbreak Technology and Exo-Cage/Triaxial Carbon construction. Any golfer, from scratch players to high handicappers, should find more speed, distance and control with GBB Epic.
Increased Distance from Jailbreak Technology
Innovative new technology changes how the head and face behave at impact to promote more speed across a larger area of the face for increased average distance.
Maximum Forgiveness from Exo-Cage/Triaxial Carbon Construction
Innovative combination of titanium Exo-Cage and triaxial carbon crown (lightest ever in a Callaway driver) and sole create unprecedented forgiveness in a high-launch, low-spin design.
Precision Shot-Shape Control from Adjustable Perimeter Weighting
Redesigned track and sliding 17g weight allows you to fit the club to your swing, providing 21 yards of shot-shape correction for more control and distance.
Faster Head Speed from Industry-leading Aerodynamics
Streamlined head incorporates our proprietary Speed Step, created with direct input from aerospace experts, to improve airflow for more swing speed and distance.
Four High-Performance Stock Shaft Options
Diamana M+, Fujikura Pro, Project X HZRDUS, and Aldila Rogue M-AX. Each premium, Tour-proven shaft is engineered to promote speed, power, stability, feel and control.

Engineers in Callaway’s R&D department introduced a bold new way to design the structure of a driver head, starting with Jailbreak Technology. This innovation inserts two Jailbreak 3G Titanium bars behind the clubface. These bars alter the behavior of the club head and face at impact promoting increased average distance by providing less bulge and flexion.
Combined with the dual Jailbreak bars, the Titanium Exo-Cage and ultra-light Triaxial Carbon Crown (9.7 grams, Callaway’s lightest ever!) work together to produce maximum forgiveness and higher ball speeds across a larger area of the face.
Who's It For?
The 17-gram redesigned sliding rear weight allows 21 yards of shot shape selection making this driver 100% for players who need to upgrade their outdated driver or simply want the latest technology. Plus to 36 handicaps.
This is one gorgeous looking driver! The attention to detail in the fading Triaxial Carbon Crown and Sole, the small Epic Green alignment highlights and shape make this one of the best looking heads out there.
I noticed right away that with a 9-degree head this driver launched at a lower angle than usual for me. The sound was more on the muted side, which seems to be the case with composite-crowned drivers. However, I’m not sure if the Jailbreak Technology has anything to do with the different sound produced.
The head provided very responsive feedback to my hands and I had no problem feeling the location of impact on the face. My flight pattern had some extra spin on it, but I felt that was due more to a layoff following a minor shoulder injury than anything else.
Since I test all offerings in a neutral setting, I did not move the rear weight to create a bias. Though, with up to 21 yards of shot shape selection, I’m positive players will be able to dial in their desired shape when adjusted.
I found the face shape interesting. The Jailbreak bars seem centered on the sole area, but not lined up with the face. This gave the appearance that they were more aligned on the heel-side. Also, the alignment aid on the top of a driver head is normally centered, but it is noticeably (albeit slightly) positioned towards the heel-side on the Epic. Overall, the Great Big Bertha Epic Driver is one of the nicest Callaway offerings I have tested.
