*OBX Synthesizer Voice Expansion & Parts from Abstrakt Instruments on Kickstarter

On Kickstarter here.

"This is your chance to help fund and procure parts for the iconic Oberheim OB-X synthesizer. This is a passion project which came about through product development & engineering. We have built and tested numerous assemblies from our favorite vintage synths for the purpose of studying the intricacies of each design. After testing, these parts are generally used in our in-house machines or neatly stored away. In the case of the OB-X, employees & visitors alike were asking to remake these parts. Since we are not in the primary business of selling parts or kits it took some convincing. These designs are completely finished. We've established a goal of $10k to make sure we have enough quantity to hit our pricing targets. If the goal is reached at the end of the funding period we will immediately send out for the parts to be made. We do not anticipate offering these parts for sale in the future. This project is more of a give-back to the vintage synth community as opposed to a practical money-making venture.

Before getting into the details of the actual parts we'll clearly state what is being offered. We are offering various voice-related parts for the OB-X synthesizer, including bare PCB's, fully assembled PCB's, and fully assembled kits.
