pretty good deal! It's got <b>the</b> Oberheim sound. The presets are actually useable. Very solid build. I like it alot. Sometimes you don't need 70+ knobs and sliders to make you happy. It's too bad you can't make new patches, though. There's alot more potential inside this machine than you are allowed to unlock.

I have the OB-Sx synth and I really like it's Jarre-esque sounds (brass, bass, lead and strings) =)! I give five ***** for it! My model is black with gray stripe on control panel. Exspecially the preset C7 gives really cool bass through Jarre's Equinoxe bass sounds (part 4,5,6,& 7 )=)! The OB-Sx was my second synth ever, while my cur rent studio setup contains the following instrumen ts and gadgeds :

Eminent 310 Unique Roland Jupiter-8 Oberheim OB-Sx Korg 01/WFd Yamaha CS1x Yamaha CSY-2A (organ with built-in synth) Roland AX-1 (red) Electro-Harmonix Smallstone phase shifter Behringer Eurorack MX2004A AKG K70 head phones Celeron PC with Reason v.1,ReBirth v.2, Cakewalk Pro 8 and various other software samplers and synthesizers. ..and soon the EMS VCS3 (new!) will join the group of my "JMJ" instruments.The VCS3 will be the last synth of mine ever, because my work as JMJ-gear collector will be crowned as it's end with owning a VCS3 =)!!

My OBSX is a 5 Voice 56 program version with the the OBXa type blue lines, and was manufactured in Feb 1982. A voice board requires a slight tuning tweak every time I fire it up, but it is a small sacrifice to make once you hear those great OBX/OBXa strings, brasses, basses and synth sounds. There's a power and warmth here that my ESQ1 (DCO's and Wave Tables) can't replicate. Remove the mutiple voice layers and effects from my X5D's "analogue" sounds and you are left with glitchy saw tooth samples and a weedy filter, that just don't compare when the OBSX is put along side.

Many sounds are very useable as they are, but having those 7 knobs helps to get some great variations. If you can't afford an OBXa this is the machine for you as it uses similar voice cards to the OBXa, but has less controls and a 49 note keyboard.

If you don't use pitch bend lever, I have a little mod that allows you to drop one of the oscillators an octave, giving you almost 100 sounds (some sounds only use 1 osc) .

As per other reviewers, try before you buy. The 56 Program 6 voice version is probably the best. No MIDI, but you can use a MIDI2CV converter with the CV and Gate Jacks to get an OB1 from Voice 1.

The score of 5 is for its sound, although it is a testament to the solid design and build quality that some machines like mine are over 21 years old.

What a synthesizer! I picked up the Oberheim OB/SX on E-bay last summer (2001). At first when I turned on the synth, it made this bizarre out-of tune noise from the oscillators (you got to warm these babys up before you start playing). But when I hit the auto button sequence for another sound memory, I heard "ONE OF THE MOST FANTASTIC SOUND THAT ANALOG HAS TO OFFER." This is a great synth. If I can recall, I think I purchased it around $375.00 but it was worth it. To me, these synths are probably one of the last great analog synthesizers. According to these synths were made from 1983 to 1985, but I'm not too sure. Mine is the 56 memory preset sounder. I'm pretty sure mine was made before May, 1985 because that was the same year that Oberheim Electronics went under & became Oberheim/ECC. Mine is also pre-MIDI. The Oberheim OB-SX is limited because it only has less knobs than the OB-8 or the OB-X or the OB-Xa. So what? It's got that "Less is More" design to the discriminating musician who can't stand too many knobs or it can be a learning too for someone who's learning about synthesizers. I like it. I'm afraid if I was to sell it, I'd never see any of these again. These are worth holding on to.

I remember those Oberheim prices of the 80's! Alas you could have that famous fat polyphonic OB osc/filter sound for half the price of an Xa...And thus the only Oberheim I ever could afford back then. Strangely, after 19 years and 40+ pro instruments which have come and gone in my rig, I still have the little rugged dinosaur around to which she still gives analog heaven and bliss delivered with a charm never to this day duplicated [like girls from the 80's]. Forged from classic XA architecture, its sonic KO is not a surprize and with a dash of effects, can still over-run a digital synth pretending to be analog hands down starting with program A1. The ones worth using today? The 6 voice 56 program version. What's missing? ...A MIDI kit!
