"E-Mu SP-12 with the Turbo Upgrade in Very Good+ condition, fully functional, and just received a $747 professional service by Advance Musical Electronics in LA — recapped, recalibrated & performing like new.

Originally a standard model with 1.2 seconds of sample time, it’s now upgraded to the Turbo edition with 5 seconds via brand-new RAM and OS (Version 2.6) chips.

Made in Santa Cruz, CA USA.

Highlights:

Boots instantly with internal RAM – no floppy boot loading, no lost work if you forget to save.

Skip the floppies: Modern tools like SP12 Librarian & EMXP make sample management easy via computer.

Lo-fi sampling tricks double or quadruple sample time with pitch shifting — that signature SP sound.

Slightly higher sampling rate than the SP-1200 (on paper) and stock ROM sounds built in.

More unique and rarer than the SP-1200 — only produced for a short time.

Ideal for hybrid setups: use the SP as a sequencer and sound shaper, with a rack sampler for long samples.

Looks cooler, sounds amazing, and (IMHO) it’s better than an SP-1200 for less than the price of one."
