Return Policy
We offer an unconditional 30-day return policy to ensure you’re completely satisfied. If you’re unhappy for any reason, return the item for a full refund or full exchange credit (reeds and other consumables are non-returnable once opened). Every instrument we sell is guaranteed to be free of mechanical defects—if an issue arises, contact us and we’ll either reimburse a local repair or provide a prepaid return label for repair, exchange, or refund. If you simply change your mind, you may still return the item for a full refund, but return shipping costs are the customer’s responsibility unless free returns were purchased through Redo at checkout. Please see our FAQ for additional details.

Brand new items are covered by the full manufacturer’s warranty unless otherwise noted (see the individual maker for details). Open box, used, and vintage items include a two-year warranty serviced by our in-house repair shop, and we guarantee every instrument will be free of mechanical defects. Warranty coverage does not include damage from accident, misuse, negligence, improper operation, unauthorized alterations or removed serial numbers, normal wear and routine maintenance, environmental damage (including perspiration, corrosion, or extreme temperature and humidity), lacquer or plating wear, or consumable parts such as springs, pads, and felts. Please see our FAQ for additional details.
