DigiTech Whammy 4, with box. I purchased this used last summer at Ishibashi Music Akihabara. I've been using it since then, but it's a bit of a hassle to put on my board because it uses AC power, and I've come to think that the Whammy 5 would suit my needs better. Also, I need to raise some funds, so I'm putting it up for sale. Operation has been confirmed. No returns or exchanges. Price is negotiable. Thank you for looking.
