The Inner guide arrangment is machined slip-fitted into a helical guide that the spring fits onto, and the 4th guide "top-Hat" has the exact spring fitting pitch allowing spring a thread like firm tighter 360 degree fit apond firing. The spring with open coils allows use of all coils for more accurate output across product line. Further, the DiY tuner has option of cuting spring for finer tuning. The new PG⁴-Guides have a near fit to its power grid with a heavier, stiffer guide adding mass for better sound deadening.
