SP-404 Works perfectly, many accessories included. Original adapter, original box, instruction manual. LEXAR 1GB Compact Flash. Oyaide CLASS B cable. audio technica cable. The successor SP-404SX and later models use a "non-compressed (16bit/44.1kHz)" recording format, resulting in very clear sound. However, the original SP-404 uses a unique compression format. Lo-Fi feel: The high frequencies are slightly cut, and the mid-low frequencies are thick and sticky, creating a "unique roughness." This produces a texture that is difficult to reproduce on current models, especially in beatmaking for Lo-Fi Hip Hop and similar genres. Bass comp-like thickness: It is said that the sound becomes thicker just by passing it through an external input, and many fans use it as a "preamp" to simply pass sound through. Overwhelmingly powerful effects The effects are the hallmark of the SP series, but the original is more rough and radical than the successors. Vinyl Sim: The original Vinyl Sim not only shakes the sound but also has a unique "compression feel." This subtly warps the beat, creating a sticky groove. Subsonic / DJFX Looper: The filter sharpness and bass response are "not too digital," making the changes when turning the knobs during live performances very dramatic. Recordable without time limits on one pad Up to 2GB can be recorded. I received this, but I haven't used it, so I will pass it on. I will carefully pack it in another cardboard box over the original box.
