This is the ANALOG.MAN SUNFACE BC-183. I bought it used a few years ago for the purpose of studying fuzz pedals. The sound is distortion-like, but also has a fuzziness, and it's really good. Honestly, I've hesitated many times about keeping it, but I'm going to pass it on to someone who will use it more. Velcro is attached to the back, so you can put it on a board right away. Side jacks. Sundial (bias adjustment), 9V jack, and LED. It has all the options you could ask for. The sundial looks like a face and is cute. I still have the original box. I think it would cost a considerable amount to order the above options from the official website. These don't come up for sale very often, so please take this opportunity. No claims, no returns. Feel free to negotiate the price.
