This is a very rare SUNFACE CV7005 version model. This version is no longer sold on the official website. It has an LED (orange) and DC power supply. While NKT275s are common, CV7005s are quite rare. Compared to my NKT275 (red dot), there is no difference in distortion or tone. I might even prefer the bell-like sound when rolling back the volume on the CV7005. Also, it's easier to shape the sound and is easier to handle than the FUZZ FACE disc type (the larger one). The unit only, with Velcro attached to the back. *Due to the high price of this item, if you wish to return it due to a defect on my part, you must adhere to the following conditions.* To prevent parts replacement, I will take detailed photos and videos of the item before shipping, and record the packing process. Please provide an unedited video of the entire process from opening the package upon receipt to testing the item and repacking it for return. Returns will not be accepted without a video. In the event of a replacement or damage, I will report it to Mercari and the police based on the evidence and take legal action. Thank you for looking.
