So, I took my Ricky to my local Guitar Center to get the bridge swapped out for a Hipshot replacement. (Yeah, sue me! lol) I had also mentioned my guitar tech that I was experiencing fret buzz somewhere between the 4-7th frets along the neck. He said he would check it out. A couple of days pass and he calls me saying that the bridge installment was successful. However, he said he had noticed a back-bow on the neck, and that the truss rods couldn't be loosened any further because they were practically as loose as they could be). With that, he suggested that he could clamp the neck for a few days to see if he could straighten it out. A few more days pass by and he called saying that he was able to straighten out the neck somewhat, but that there was still fret buzz along the same area of the neck. He believes that some of the neck is still warped because he had already set the action pretty high, but to no avail. He suggested a fret level/polish to compensate, but that's quite pricy and I'm not down to do that to relatively new frets (the bass was made in 2014, got my hands on it new in 2015). With that being said, what could the problem be? Could the truss rods be the culprit? Sorry for the long-winded story, I had to throw as much detail as I could, haha.
