I was jamming with some guys from the midwest over the summer.
Their guitar was tuned in a way I've never played before.

The first and second strings were tuned the same (so if 1st was E, 2nd would also be E)
as well as the 6th.

I can't remember what this tuning was, but the guy who was playing it had a western-style influence...

It was so much fun playing this tuning....I loved it.

Does anyone have any idea what it could be?

I would be so grateful.... thank you all.
