“Hey guys,
So obviously I’m selling my Op-1…
It’s kind of weird to write this description because I love this thing so much and parting ways is going to be tough. Fortunately, I need the money in order to move to Vegas for my DJ career, which was largely inspired by the use of this instrument. It is such a funny part of life that things come full circle this way.
Something I want to point out is that the OP-1 isn’t for everyone. However, it is a great instrument that can help someone who is more of a newbie and wants to learn about synthesis as well as drum patterns. Really cool tool for sampling (because of the microphone) groovemaking, and inspiration for sounds.
As far as the condition of the instrument itself, I bought it two years ago after wanting it for about 5 years. It is very clean as I have always stored it in a case. No damage and all original working parts. It has outstanding battery life and has the charger included in the case.
If you buy this thing good for you, I would be interested to hear what you create! Happy hunting and best always.”
