Alex.. You can downtune and still not have a problem.. You just have to adjust the bridge so it raises the strings up a little higher so they don't touch the fret markers when you're downtuned low.. I have my truss rod and bridge adjusted so it's perfect downtuned 2 steps (that's where I usually am) So when i'm tuned to concert pitch my truss rod is all farged up and the action is so high it's like a jacked up chevy truck.. That's why I have two guitars. I keep one so I have a guitar for concert pitch - half a step either way.. and then my other for the lower stuff.. It really makes things go alot faster.. don't have to worry about tuning your guitar THEN worrying if the strings are going to buzz because they're hitting the frets or if your neck is going to warp to hell from the truss being so tight.. So downtuning isn't so bad.. there are just precautions to take that's all..
