I use it all the time for miking my guitar amp.

When playing live, i have my amp facing me as a monitor, so i just hang the mic over and get rid of additional guitar mic stand.

That way it saves me space for the pedalboard, a monitor and vocal mic stand.

It also works great paired with a 57 if you have a bigger cab (like 4x12) for a heavier guitar tone.

Fantastic mic, i strongly recommend it!
