I'm currently playing a song that's in the tuning Eb B F# B B E (low to high). I'm positive that the song is in that tuning. Would leaving my guitar in that tuning damage the neck over a period of time? How long would it take to damage it?

The tension differences aren't too huge. Except in the G and D strings, are those tuned UP to those?

My things:
Bowes SLx7
Washburn WG587
Washburn X40Pro
Washburn X50
Washburn HM24
Washburn WR150
Laguna LE200s
Arietta Acoustic

Just get some lighter strings and you're good to go
