none of them.
Hate the EMG 'clean' sound. Some love it.. but it ain't to my taste.
sucks balls.
More often than not, but definitely not always. I love the EMG single coil sound you hear from people like Cynic, David Gilmour, etc.
For my tastes, the best clean sound you can get with EMGs would be by using single coils. I don't really dig the 60/60-7 sound... It doesn't sound like a single coil to me... just like a brighter humbucker with a kind of weird 80s voicing I don't particularly like too much.
The 85/707 in the neck can be okay for cleans, but not great... too hot, not bright enough. I sometimes use the middle position (on a guitar with 707s in bridge and neck) to get a brighter sound and just keep the volume knob halfway down to tame the output. It's not ideal, but it's workable...
The 81/81-7 in the neck seems like it'd have too much output like the 85/707, except more cold and crunchy sounding due to it being ceramic... I don't really think I'd like that, but I can't say for sure. The 81TW probably sounds great in the neck in single coil mode though.
I say 89 or 707TW in the neck position... use humbucker mode for leads and single coil mode for cleans. Not sure how much Sneap digs playing with clean tones, but he is quoted on the EMG website saying the 81TW bridge/89 neck combination is his favorite because of versatility (both humbucker and single coil options in each position).
I'd have to agree. I'm digging the 81-7 bridge/707TW neck combination right now.... which is as close as you can get on a 7 string, because there is no 81-7TW at the moment... My guitar only has a single volume knob (no tone knob) though, so I can only have a push-pull pot for one pickup anyways.
I believe James Murphy also uses the 89 in the neck, although he uses the 85 in bridge instead of the 81.
