UK Project Guitar - Hofner Parts Shop: https://www.projectguitarparts.co.uk/Pages/hofnerparts.html This is a personal import I ordered in 2011 from the above shop for repairs to my Hofner bass. I am selling it because I no longer need it. 【Features】 Control Pot Spline Shaft 500K Control Pot, Spline Shaft Select Option: Control Pots, Spline Shaft A500K Pot top marking: DC500S. ◆【Defective】【Notes on Replacement】: The screw thread diameter is 7.5-7.8mm, and it is necessary to enlarge the pot hole in the control panel from 7mm to 8.0mm. By the way, it does not affect the replacement, but the total length is also about 5mm longer than the current pot. (See measurement image 9) ◆This item has been stored at home for a long time. ◆Control pots are consumables. How about for replacement or spare parts? ※Although it is an unused item, please note that there may be fine scratches and stains due to long-term storage. Thank you for viewing.
