【Image Added】 It appears to be a 78mm stud spacing, not the standard 74mm. Compared to a FERNANDES FRT-5PRO (original Floyd Rose and Gotoh are the same size), the measurement at the worn area of the knife edge was approximately 78mm. Please be aware that this is a special size. It's a licensed Floyd Rose, but it doesn't seem to be the standard size. It doesn't fit my FERNANDES, B.C. RICH, or genuine Floyd Rose, and the stud positions are slightly wider than those. It might be for YAMAHA, but I'm not sure. The dimension of the 6 saddles is 63mm. The sustain block is around 41.5mm. With arm. I think the condition is not bad. I like the heavy construction, which is better than recent new Chinese-made ones, but I don't have a guitar that fits it... It might be good for those who are going to build their own guitar. I plan to remove the block and flatten it for shipping. I try to ship the next day, but I will process the procedure within the business hours of the Yamato Transport office. I may not be able to ship the next day due to my busy schedule, but I will contact you, so please understand. ・New users on Mercari, those with no transaction history ・Those who are nervous ・Those who give a bad rating after lowering the price without saying thank you ・Those who cannot communicate via messages ・Those who use rude language ・Those who are not good at handling musical instruments and effectors ・Those who take a long time to rate after receiving the item I am sorry, but please refrain from purchasing.
