"Turn that amplifier down!" they shout.
"But I can't hear myself!" you protest.
"We can't hear anything but you!" they retort. And turn their own amps up...
And so the onstage volume war begins, escalating ever upwards. It leads to the destruction of musician's ears, and is the bane of soundmen worldwide, as onstage volume gradually overwhelms the front of house PA system.
How does this come about? Musicians often place their amplifiers on the floor next to where they are standing. However, speakers are quite directional, especially in the mid and high frequencies that allow you to pick out your own sound amongst the mush of live sound.
But feet don't have ears, so it's easy to set the volume to a comfortable level for yourself, while deafening another musician 10 feet away. Add in rumble transmitted through stage floors finding its way into open mics, and the problem worsens.
This stand goes a long way to solving this problem, through application of the completely obvious - it points the speaker towards your ears, so you can actually hear the sound you are making.
I use it with my 1x10 and 1x12 bass combo amps, and it supports their weight perfectly well.
Buy one for yourself. Even better, buy them for your whole band. If they are open to enlightenment, they will thank you, as will your sound man and audience.
