This is a Roland Cube 30. As you can see in the photos, it's in pretty good condition for its age. There are no issues with its use. I think it's a reasonable amp for those looking for a Jazz Chorus (JC). No returns or exchanges. The CUBE-30 is a personal guitar amp with a 10-inch speaker and 30W output. It features 8 types of modeling amp sounds using Roland's unique "COSM" modeling technology. You can enjoy a variety of amp sounds with just the CUBE-30, such as "JC CLEAN" with a pleasant high-frequency extension, "TWEED" with a fat mid-range that's a perfect combination with single-coil pickup guitars, and "R-FIER" with powerful, thick low frequencies. Furthermore, the CUBE-30 has a 2-channel configuration: clean/lead.
