Hey there, These came off of a Japanese Fender Precision PB62. The guy I bought it off of said that these were TI Flats, but I can’t be a 100% certain. So this will be a as-is kind of deal. I am a rounds player, so I changed them pretty quick. I am not too familiar with flats and I haven’t had these on a bass in quite some time. They have just been sitting in my drawer. If you have any questions, let me know! Thanks!
