I cant say im a newbie XD but i adjusted my floyd 1000 times now, but i couldnt get it to work for a long holding tuning :/ i was once in the shop and they didnt told me that there is nothing to adjust... so i tought that maybe the screw which are screwed in the body are loose or something OR the fine tuners are toooooooo loose... idk if im right but it could be a possibility too... i know that JT580 isnt a great trem but i dont know if the Original FR would be better... i heard that Ibanezs EDGE are much better, but the next question is if it would match in the hole :/ ?!
