What do we mean by “refurbished”?

Refurbished can be an arbitrary term. It means different things to different people. We can only speak for what refurbished means to Rankin, and have outlined specifically what we do to our instruments to deem them “refurbished”. Every instrument undergoes a systemized, rigorous, down-to-the-frame refurbishment process to rebuild each instrument to its original specifications and intended use.
