The Force BalanceTM system in Tensor Basses replaces the conventional truss rod found in most all bass guitar necks. The Force BalanceTMsystem utilizes the string tension to generate the appropriate counter tension on the neck. Since the counter tension is directly proportional to the string tension the two forces balance each other under a wide range of varying conditions. The effects of temperature, deformation and stress relaxation are dramatically reduced resulting in a more stable neck assembly.
The Force BalanceTM system has an adjustment feature which introduces a small positive or negative force to the system to allow for precise adjustment of neck bow to accommodate the players preference. The adjustment system uses constant force compression springs which are not susceptible to the variations found in the conventional truss rod adjustment mechanism.
