BOSS DR-550mkII Rhythm Machine | Powers On, Noisy - Sold As-Is (Junk)

Rhythm Machine
Model Name: DR-550mkII

Power has been confirmed with the AC adapter, but due to unstable power connection in some areas and significant noise in the sound, this item is being sold as a junk item.

When tested with the headphone jack, a loud buzzing noise was heard, and the drum sounds were faint, as if playing from a distance.

*Please note that other output methods besides the headphone jack have not been tested recently.

The display has screen burn-in, but the display itself is visible and the text is legible.

Previously, with the aim of improving the noise, the unit was disassembled once for cleaning and internal inspection. Unfortunately, I was unable to repair it, so it is being sold as-is.

The AC adapter is lost and will not be included.
We kindly ask that the purchaser provide their own.

We hope to sell this to someone who can repair or maintain it, or who understands its use for parts or research purposes.

As this product is a junk item, please purchase it after understanding and acknowledging its condition.
We regret that we cannot accept complaints or returns after purchase.

Thank you for your understanding.
