Thank you for looking. This is the 818 Overdrive from [Pedalman / Landgraff]. This was created by Mr. Landgraff as a prototype before he created the Dynamic Overdrive. It is an extremely rare and valuable item, with only about 50 units made, and is sometimes referred to as a "phantom effector." Although it has been featured in famous books and other publications several times, it is generally not available on the market. I have owned quite a few Dynamic Overdrives, but I felt this one sounded better than any of them. I believe this is an indispensable item for Landgraff fans and collectors. Please note that the serial number in the image has been obscured. As this is a high-value item, it will be shipped with insurance. Due to the extreme rarity of this item and to prevent parts swapping, returns will not be accepted for any reason. We perform thorough operational checks and careful packaging before shipping. If there are any issues upon arrival, please contact the shipping company's insurance. This item is also listed elsewhere, so we apologize in advance if it is sold out and we have to cancel your order. I have many other effectors for sale, so please take a look if you'd like.
