GAMMA Polyester Strings: All You Need to Know

By Chuck Vietmeier, Director of Product Marketing |

Choosing the right polyester string can be challenging for today’s hard hitting spin generating baseline players. Polyester strings are available in so many shapes, gauges and textures that can be difficult to make the best choice for your game.
The GAMMA AMP polyester series gives a player three premium choices for intermediate and high level players who rely on a consistent feel and want power when needed on all strokes. AMP polyester strings are manufactured using an advanced high molecular weight co-polyester material. The benefits are increased strength, minimized tension loss, and maximizes durability and longevity, providing ideal conditions for the player during match play. Power hitters and tournament players are drawn to the technology because of the extreme control this poly string provides. We offer the AMP string in three different types that all offer great control and power with varying degrees of spin potential. Here is a description of each to help you decide which model would be best to take your game to the next level.


GAMMA MOTO is a seven sided co-polyester that offers a nice feel while delivering crisp accurate placement on serves and groundstrokes. The softest polyester in the AMP Series, MOTO offers big hitters looking for MASSIVE spin and pinpoint accuracy with a comfortable feel. This shaped poly rewards the biggest swings with a heavy, spin-loaded ball. MOTO is available in 16 and 17 gauges and two colors.


GAMMA OCHO is an eight-sided string that is perfect for hard hitting players that want a stiffer string bed for maximum control. They prefer the ball to flatten out and stay on the string bed for precise accuracy and exceptional feedback. OCHO is available in 16 and 17 gauges and two colors.


Firm and precise, GAMMA JET co-poly has outstanding control. As a result, a player will find it easier to attack the ball with their most powerful strokes. This string is shaped, then twisted during the extrusion process for extra grip on the ball (think spin). Perfect for intermediate and advanced players looking for control, spin and durability. At under $10, this is an obvious choice for value hunters. JET is available in three gauges 16L, 17 and 18 and 4 colors.
