Anyone know how low you can tune this thing without causing problems? Can you tune down a step or 2??
Depending on the string gauges you use, it can go down as low as you want. But, I believe it's only got a 25.5" inch scale. So you're either gonna need one hell of a B string or get used to excessive B string flub.
But would a different gauge work pretty good?
Yes. The heavier the string gauge, the tighter the strings will be as you drop the tunings. But you'll still have to worry about flub on the B string. If you're going down below a full step, I would suggest a B string between the range of .065-.070.
i have that guitar n w/ 10-56 i could go down a whole step, never really tried anything lower w/ it tho
