This represents a rare opportunity to buy an OB-SX that works perfectly, tunes better than others, and will hopefully keep working perfectly long into the future. We wouldn't sell it if we didn't have another just like it in our studio collection.

For years, we avoided buying this vintage analog polysynth because it was preset-only. However, someone recently created a MIDI retrofit (not included) that plugs into the communication port on the back of it that also allows for full editing of all parameters via MIDI CC data, bringing this synth up to the legendary level of the OBX, OBXa and OB8! To us, it sounds like a cross between an OBXa and OB8, plus it's got the benefit of being smaller and lighter. Even without this retrofit, it's a great synth with knobs for some very important parameters on the front panel so you can make adjustments to customize the preset sounds. 

Here's a video of this OBSX in action:

Made in the U.S.A and Cash the Border Collie LOVES them! No stomach upset!
Our dog, Cash the Border Collie is 55 labs and he LOVES these. We bought these a while ago and they were put away in an odd cupboard. Found them a couple days ago and I decided to see if Cash would eat them. He is not much of a rawhide dog. Well, I think we have found his brand of BEEFHIDE He is one happy camper with this treat! We bought these mainly because they made in the U.S.A. While they may not be the all natural ingredients some look for, it is a treat and he likes it. 20 pk Assorted Beef and Chicken 5" rolls (Chip rolls) 100% American Beefhide Follows GFSI food quality standards Ingredients: American Beefhide, Maltodextrin,Chicken flavor, beef flavor, Caramel, Hydrolized poultry Liver, Brewers dried yeast, Guar Gum, mixed Tocopherols. Ok, the yummiest part of the ingredients to me is the Caramel. I know, bad for Cash's teeth. But he will get these ONLY if he is a Good Dog. And if you look at the front of the package the dog is saying 'I've been good.' The beef flavored ones did leave a small stain that I cleaned up easily, but really, he ate it within 10 minutes so not much of anything. I think the people who are complaining about staining have dogs who are slower chewers. No staining with the chicken flavored rolls. Cash does not seem to care if he gets the beef or the chicken. At first he licks the roll for a minute or 2 and then he can't wait any longer and the chewing begins. He has not had any diarrhea or any other stomach problems with these. They are small, but we knew that when we bought them and we knew they wouldn't last long. That's ok, they are a treat, not a bone for him to chew on forever. Hope you like the pictures. Sorry about he red eye. If you find this review helpful, please click the button below.
