Roland SP-404MKII LINEAR WAVE SAMPLER Beatmaking Machine I pre-ordered and purchased this when it was released in 2021, but I've hardly used it (about 30 minutes total), so it's become a complete waste! I'm selling it. After purchase, it was stored in its box. Operation has been confirmed. Pads, knobs, etc. all work without issue, but this is based on my amateur assessment. Also, although it's practically unused, it is a used item, so returns are not accepted.
