Thank you for viewing. Power-on operation confirmed. Knobs show some whitening. Scratches on the stainless steel surface of the main unit. 1GB memory card included. As a bonus, a printed instruction manual is included. There are scratches and signs of aging, but overall, it seems to be in good condition. Please refrain from purchasing if you are sensitive to used items. Feel free to ask any questions or request additional images. Thank you. Sampler Effecter sp404 Roland Roland
