I recently acquired an older USA Jackson with a recessed JT6. I swapped out the JT6 with a brand new OFR, and I rethreaded the original inserts to take the new OFR posts, which allow for a greater range of motion than the JT6 posts. My Jackson has a 25.5 scale and is in standard tuning with .09 gauge strings. I have the Floyd set up with three brand new springs that came with it. My problem is that it is very stiff, so much so that it is difficult to dive bomb and I can barely pull up one half-step. The Floyd and block have plenty of clearence and arent hitting the body. I've used Schaller floyds and Ibanez Edge trems in the past with 3 springs and they feel like butter and are smooth and effortless to use. Any idea what is wrong with my new OFR?
