You need this product if:
Some or all of your balance and/or rail felts are missing
Your keyboard has been played extensively at any point in time, and the felts are old or original
Your keyboard has evidence of moisture damage in the keybed
Balance rail felts help the keys play smoothly, and, along with paper shims, they help ensure that all keys are level with one another. Compacted felt will give the keyboard an inconsistent feel and reduced level of playability.
It’s also really common for the balance rail felts to absorb moisture over time—for instance, if your keyboard was ever stored in a humid place (i.e., any shed or garage outside of an actual desert), or if anything was ever spilled in the keybed. Old, dirty, moisture-damaged felt makes your keyboard smell musty.
So, if your Rhodes balance rail felts are original, replacing them will improve your keyboard’s playability (and probably its smell too).
