GORE-TEX® pads: are fish-skin pads, covered with a thin layer of GORE-TEX®, a waterproof material designed by the clothing and shoe industry to allow your feet to breathe. Repeatedly weve experienced these pads becoming damaged and causing serious problems due to water infiltrating them. When that happens the felt inside the pad can suddenly expand to twice its size and the instrument is unplayable. Therefore, we no longer use GORE-TEX® on our L&P setups. On new instruments, we recommend replacing GORE-TEX® pads within two years.
