Thank you for viewing. This is a listing for the **CAJ RS-616**. • Condition: Used until recently. Switching is working normally. The exterior has minor scratches and signs of use commensurate with its age. • Effects Loop: Some jacks are chipped (see photos). I rarely used the loop function, but a quick check suggested it was working. However, there is a possibility of malfunction depending on the exposed jacks and how they are plugged in. Please consider this when purchasing (no operational guarantee). • Repair History: When I purchased it used, some of the function switches were sticky, so some were repaired under warranty. It has been working without problems since then. • Sound Characteristics: Although it's an old unit, it's CAJ (CAE) quality, and the sound through the buffer is warm, and the switching was stable (subjective). • Accessories: Everything shown in the photos (items not listed or shown are not included). • Notes: This is a used item sold as-is. Please refrain from purchasing if you are looking for perfection or are concerned about the chipped loop jacks. No returns or exchanges to prevent swapping. Anonymous shipping and carefully packaged.
