New OLED LCD, New Battery. Display Contrast MOD was installed for variable brightness level of the LCD. Unit was professionally cleaned and calibrated as well. Only minor aesthetic point that needs to be addressed is that the last slider on the crash is slightly different from every other slider. The price is reflective of the cost of the unit, the hardware upgrades and technician service fees. Shipping is based on location. So the closer you are, the cheaper shipping may be. I reserve the right to ship this item through a different courier if I choose (Fedex, USPS or UPS)...The E-mu SP-12 is the classic drum machine & sampler combo that paved the way for such greats as the E-mu and AKAI series of sampling drum machines. Redesigned from E-mu's original drum machine, the SP-12 is a classic drum machine with built in sampling capability. There is a set of preset drum sounds including kick, snare, hihats, toms, cymbals, handclap and rimshot. These sounds can be mixed and edited using the sliders. Then you can add your own beats and drum sounds using the built-in 12-bit sampler. Sampling time is limited to only a few seconds and the quality is very lo-fi (a sound loved by lo-fi and trip hop). Store your patterns and link them into songs, there's room for 100 of each! There are mono and individual outputs (no stereo)
