Hi all, I have a ST24 with 10-46's on right now (in Standard), and I'm thinking of tuning down to C# standard (or D flat - the official terminology doesn't seem to be clear and some get upset at calling it "standard" - not the point of this question ). Thing is, I don't have money to be re-setting it up, and I only have one guitar. I have a good setup on there now, and don't have the money to pay to get it set up in C# and then back in E afterwards. A few questions: 1. I know the PTC does amazing setups, but setups don't seem like rocket science to me - is it easy enough to set up your guitar half-decently (not perfectly, but decently) in this sort of scenario? I can be precise. 2. What string gauge should I use? The D'Addario chart tells me 52's, but I've heard 49's work fine. Any suggestions for similar tension to 10's in E? 3. Is the string gauge difference enough to warrant nut filing, and/or a new nut for switching back to E later on? EDIT: For some reason I can't add paragraph spacing on here, makes this harder to read.
