Hey all, I snagged a second hand RG8FM as a first 8 string to see how I like it. I'm pleasantly surprised at the quality of this instrument. Even the pickups aren't horrible. That's a first for me and an Ibanez guitar. There are some things I'd like to get clear, so I can get it set up just right. 1) Action on some of the strings make the saddle screws stick out a bit. I hate that, so looking to replace them with shorter screws. Are these height adjustment screws always the same size (length and or width), or does it differ per producer? 2) Neck relief is a bit off the chart and that's probably also why the saddles are put a bit too low, so I had a go at adjusting the truss rod. Two full clockwise turns and a fair time of waiting and I don't really see any difference. My other guitars would react to the tiniest adjustment. So I am wondering, could this guitar have a dual action tross rod? Really don't know and wouldn't want to take out the neck pickup to find out if it's not necessary. 3) I went ahead and ordered a D'addario 6 string+2 singles set, with a NW080 as the low F#. I didn't really think about whether that will be tapered and if I will have issues fitting it through the tuning peg. I dislike the idea of drilling it out. Currently it has a Ernie Ball 080, which in fact is tapered, but man do I hate Ernie Ball strings. Whaddayathink, will I have issues with the NW080? Any recommendations for other singles that can be purchased in Europe if the NW080 will not fit easily? 4) Finally, the screws for the pickup selector switch are a bit worn and oxidated. I see online shops selling pickguard screws. Would these screws fit?
