Roland JX-8P: Detailed Service, Repair + Demo Track~

Please join us while we sort through this Roland JX-8P from 1985! These synths are one of the few vintage analog synthesizers that you can still find for reasonably low prices. They have some common issues; we address a few of in this video. The 8p has a warm buttery sound and they are capable of beautiful analog strings and pads. The 8p would be a fantastic addition to any vintage synth enthusiast's studio!

The background music & demo track using this synth @ the end are also all original content!

This is our very first video, so please like and subscribe if you appreciate this type of content. We'd love to continue doing more, but each of these takes an incredible amount of time and effort. We are just two extremely passionate synthesizer enthusiasts; these videos are made as we have spare time. Your support would be greatly appreciated!

Additional Caveat: This video is for demonstration purposes only. Proceed at your own risk & liability.
