I purchased this new from the Ikebe Gakki web shop on Rakuten last year and only tried it twice at home. I operated it by hand. It's as good as new and in beautiful condition. It comes with a warranty, valid until July. I only bought it out of interest, and since I was satisfied after trying it, I decided to sell it to someone who wants it. I will carefully ship it via Takkyubin (home delivery service). - Brand: Elehamo - Model Name: Small Stone Phase Shifter - Type: Bass Equalizer Thank you for looking.
