@Connor > Although the faders are the most susceptible parts of controllers, for them to be bleeding after 2 years of light use is definitely a rare case. I have seen SX's that look liked Mike Tyson's punching bags and still have no fader issues. Was any liquid ever spilled onto or into the unit? Was it ever dropped? You can try fader cleaner. It evaporates relatively quickly. Just be sure not to use too much at once. Apply 1 or 2 quick sprays and move the fader rapidly until the liquid dries. Repeat this process a few times on each fader. Please let us know if this solves your issue.
