Buying Guide

  • 1Test every key for velocity sensitivity and make sure none are sticking. Key contacts are a common repair on older synths.
  • 2Check if the internal battery is still holding presets. A dead battery means lost patches on many vintage synths.
  • 3Ask about any modifications or repairs. Synth modding is common and not always negative, but know what you're getting.
