Okay so I think I am going to go forward with the SG and get some work done, though I am really a keyboard player. I don't like the feel of the outside edges of the frets on the thumb side. I want to get them buffed down. I also need to have the nut either cleaned up, have graphite added, or just get it replaced, because I have some fret buzz from the 1st to the 5th fret. And while I am in upgrade mode, I may as well put new tuning machines on it. And that's what I want to hear suggestions about. I like Hipshot tuning machines, but I am sure there are other good ones out there. What suggestions might I hear from anybody who has swapped out the tuning machines on their SG? They would run me $50. Also, I did read my pots and they are 500k, but are their differences in quality of 500k pots? Would you suggest Gibson OEMs? For what pots cost I may as well have brand new ones put in while my guitar guy has the guitar anyway. Maybe even a better switch.
