Used Gear Conditions

Condition 1 - Mint Condition

This instrument or product has been carefully played/used and returned to us in virtually new condition, however its packaging may not meet the standards set by the factory. Also, it no longer carries the manufacturer's warranty. If you're looking for a virtually new instrument in possibly less-than-perfect packaging, this is a great value. We feel so strongly you'll like what you see, we're including our 30-Day Satisfaction Guarantee to this used product making it a no-risk purchase.

Condition 2 - Gently Used

Very Good: This instrument or product has been carefully played/used and shows few, minor signs of use. In most respects it looks and performs like new and may be considered equivalent to display units found in retail stores. Its packaging may not meet the standards set by the factory and it no longer carries the manufacturer's warranty. Condition 2 products are a terrific value and you can buy with confidence knowing our 30-Day Satisfaction Guarantee applies to this used product.

Condition 3 - Good Condition

This instrument or product is in good working condition but has one or more cosmetic flaws beyond those of a Condition 2 product. These flaws are typical of an instrument or product that's seen normal wear and tear, including incidental scratches, chips, dings, dents or other imperfections. It performs just as well as a Condition 1 or Condition 2 instrument/product. Its packaging may not meet the standards set by the factory and it no longer carries the manufacturer's warranty. Condition 3 is a great choice if you're looking for performance and value and not as concerned with cosmetics. You can buy with confidence knowing our 30-Day Satisfaction Guarantee applies to this used product.

Condition 4 - Fair � Needs Repair

This instrument or product is not in working condition and needs repair, but can be brought back to full functionality with replacement of parts or some skilled repair work. If you are a do-it-yourselfer or know a skilled repair person this is a terrific value. Condition 4 products are sold AS-IS: they do not come with a manufacturer's warranty and are not returnable.

Condition 5 - Poor � Parts Only

This instrument or product has been damaged beyond what we judge is reasonably repairable. It's best used for spare parts or to practice repairs on, and at this price Condition 5 products are sold AS-IS: they do not come with a manufacturer's warranty and are not returnable.
