Got a quick win today: the pitch bend spring on my SH-101 had finally given up. The original (a tiny, coiled thing inside the pitch bend lever) had lost enough tension that the modulation felt sticky and unresponsive. No dramatic failure—just a gradual decline over months of use.
Replacement was straightforward. Sourced a spare from a parts supplier (they had one in stock, which surprised me). The spring itself is a simple component—no fancy electronics, just a metal coil that pushes the lever back to center. Took maybe 15 minutes to swap it out: unscrew the lever, remove the old spring, install the new one, reassemble.
No need to recalibrate anything else; the SH-101’s pitch bend mechanism is forgiving that way. Now it feels snappy again. Small fixes are the best kind, right?
