After nearly 20 years, my old Fender Jazz (actually a Squire - one of the very first Fenders from Japan, I believe) looks to be due for some new frets in the not-so-distant future. Being not terribly savvy about such things, I'm wondering what my options are. I have some notion that I could opt for rounder or flatter frets, of various heights, but I don't really know what differences these choices make. Some insight on this would be much appreciated. In case anyone might go even further and venture a recommendation, some specifics: Although it's a lowly Squire, this instrument has retained it's position as my main axe even as others have come and gone. It's been fairly well customized and I would spare no reasonable expense in refretting. Maple neck with rosewood fingerboard. I prefer a 'medium' action because I start out playing with a lighter touch but when things get revved up in a rock band, I start playing fairly hard. I play fingerstyle and some slap, through an SWR rig set to achieve the SWR 'signature sound'. I am now using nickle strings and plan to continue. The frets currently have some abuse due to some stainless-string indescretions back before I knew better, but no more stainless strings for me, in any case. I'd like to enhance 'playability' of this instrument but don't know how frets would influence that. Thanks in advance for any advice on this issue.
