Thank you for viewing. This is a used Roland JAZZ CHORUS-22. Operation has been confirmed. There is no scratchiness when operating the knobs, and there is no looseness in the jacks. We generally do not accept price negotiations. We will consider adjustments as we see fit. To prevent trouble and product substitution, we do not accept cancellations or returns after the product has been shipped. Please be aware of this. I have a cat, so cat hair may adhere to the product or packaging. If you dislike cats or have a cat allergy, please do not purchase this item. This item is stored by an individual, so those looking for items as clean as those in a specialty store or those who are very particular should refrain from purchasing. We cannot issue receipts. We use recycled materials for packing cases when shipping. We also use newspaper inserts. Thank you for your cooperation in saving resources and reducing costs.
