Help me with a tattoo cover-up

I have had a tattoo for years and want to get a cover-up on a certain part of it.

I need to cover up the pistol with something audio related (a waveform or something audio related)

I need some ideas

Try to make it look like he’s holding up a old 90s subwoofer with some waves of sound and some tiny musical notes coming out of it. Also I would go around the tattoo and spice it up so it all looks like the same tattoo and not two separate designs

I agree with the above comment, you will need to get the whole thing re done, or cover the complete tattoo, maybe with an old style microphone
