I've never truly understood why so many guitarists put tape on their amplifiers.
I have seen many YouTube videos where, before recording and placing a microphone towards their amp, they will put tape in certain places across the fabric of their amplifier before recording and never explain why! What is the reason for this? I definitely know it's not because the fabric of their amplifier is damaged in anyway because their amps are perfect! The best reason that I could think of is that somehow by straining the fabric it could increase resonance?
Why do guitarists put tape on the fabric of their amplifier? (excludes to repair the fabric)
The photo below isn't the best of examples since it doesn't have a lot of tape, however, it was the best one I could find.
