I'm kicking myself. If I'd thought ahead, I should really have done a "before and after" set of photos as the results surprised me a bit. I recently traded a really nice acoustic for a good-looking 2001 model SG. There was barely a scratch or a mark on it. It had been played but not excessively. I doubt it had been played for a while as the strings were very dull sounding and the wound strings looked to have a fair bit of dirt / rust on them. The fret board looked a bit grubby and the mother of pearl inlays appeared "flat" compared to others I'd seen on new(er) guitars. The action seemed a bit high and the intonation wasn't right - even to my novice ears. So, I tracked down a local luthier who has a very good reputation. He asked me to drop the guitar off - which I did. I know how to change strings and tune a guitar but I'm not confident about the more technical stuff and, as it's not a cheap guitar, I reckoned it was best to have an expert set it up properly. I got it back last night and what a transformation. Action lowered. Intonation set up as perfect as can be. New strings (supplied by me). Frets polished. Fret board cleaned up lovely and "oiled". The inlays now look fresh and almost 3-D. Pots cleaned. Pickup covers and body are now sparkling. Aside from the pick-up guard having the usual array of fine scratch marks, it looks almost like a new guitar. Anyway, I was a little sceptical about how significant a difference a set up would actually make but I am both surprised and delighted. I'll try to remember to take and post a few photos of the "after". I have a few more guitars that I bought from new but that could be set-up better than when they came out of the factory - so I'll be getting them sorted over the next few months.
