◆ This product was purchased used approximately 25 years ago. I rarely used it back then, and it has been stored for a long time. Upon checking its operation for this listing, it works normally without any crackling. Although the detailed specifications and manufacturing year are unknown due to its age, it features a very three-dimensional sound with beautiful chorus/delay sounds that feel like humidity. In addition to the beautiful analog sound, it's a delay that allows for a wide range of settings, making it enjoyable to experiment with. And, the chorus is especially exquisite, with a thickness, presence, and beauty that cannot be replicated digitally. I believe this sound will perfectly fit genres from classic rock to neo-soul. If you are feeling unsatisfied with recent digital chorus/delay effects, I highly recommend you try this sound. I think the number of these units is dwindling, so please consider it if you are looking for one. For a product of this age, the logo print is clear, and it appears to be in good condition. Please purchase only if you understand the condition of a used and long-term stored item. Returns and claims are not accepted after purchase. It will be carefully packed and shipped. ※ No accessories are included. This is a listing for the main unit only.
