I think you're better off buying the Suhr FLs from TGP or online, cheaper than G77 even with shipping. I just bought the specials last night and installed them: They're really fantastic. Lots of clarity in every position, even in positions 2 and 4, where the characteristics of that position tends to get drowned out playing with distortion, but the still stand out very clearly and I really like that. The pickups are slightly more mid-rangy-er than most single coils, but that really helps them to cut through the mix very well.
Strum a chord with the pickup in the neck position and it's just really clear, even with distortion. Single notes sound nice and thick with a nice amount of bite to them.
In conclusion: These pickups work well in almost any context, from jazz to blues rock to djent and prog metal(yes I actually managed to churn out some awesome Periphery and Mastodon tones with the pickups)
Definitely recommend it to anyone looking for a single coil replacement!
