VEMURAM Butter Machine Serial number in the three digits, I think it's from the early production run. I used to use it alongside a Jan Ray, but I was much more impressed with the Butter Machine. It gave me the impression of a much thicker sound with rich overtones, a lustrous and dirty distortion. It also excels in picking response, allowing you to control the nuances with your guitar, making it a new kind of distortion pedal. In addition to the knobs, there are two trimmer adjustments on the side, allowing for a wide range of sound creation, making it suitable for a wider variety of genres than the SD-9. I think it will be very useful in sessions, etc. No operational issues, used only indoors. There is Velcro on the back, but otherwise, there are only minor scratches, and I think it's in relatively clean condition. Accessories included, no box. Please understand that this is a used item, and please purchase with the understanding of no returns or refunds. ◇◇◇◇◇◇◇◇◇◇◇◇ #Vemuram #Overdrive #Distortion #Fuzz
