On a 24.5″ scale, C is about as low as you van get without resorting to Mike Hedges types of string gauges. 🙂
Fun tidbit of info about open G: “Ohhhhhh. THAT’s why Macawber* only has 5 strings.” The low D gets in the way as often as not.
Though I’m having a lot of fun with “Wayfaring Stranger” playing the Dm like this: 020233. Fattest fretted Dm chord I’ve ever heard.
*for those who don’t follow this stuff: Macawber is one of Keith Richards’ Telecasters.
