I realize I might be starting a $#!+ storm with this, as there will certainly be strong opinions either way, but I was wondering about the advantages and disadvantages between level and tilted amp stands. The idea with PA speakers is to put them above everyone's head to reduce obstruction of the sound. The idea of raising a bass amp is to allow the low frequencies to travel out better. So, would it be better to point your bass amp skyward, as it were, rather than straight out? Or would tilting it point the sound too far over everyone's head and just bounce it off the roof, or worse being on a patio and having the sound disappear into the night? What say y'all?
