No.
A stomp box usually uses a 9v battery or an AC adapter.
Phantom power is only needed by condenser microphones or certain active DI boxes and maybe some other niche pro audio gear.
"Phantom power" is called that because it is a method of providing power to certain audio equipment without the need for a separate power source. The power is sent through the same cables that transmit audio signals, making it seem as if the power is "phantom" or invisible.
No, dynamic microphones do not require phantom power to function as they generate their own signal. Using phantom power with a dynamic mic can potentially damage the microphone or adversely affect its performance.
The MXL 990 will not work directly into your computer as it needs "phantom power." Phantom Power is 48v run from an interface or mixer to the microphone to power it. Most condensers either need phantom power or a wall adapter plug or they can receive no power.
To connect an XLR microphone to a 3.5mm input with phantom power, you will need an XLR to 3.5mm adapter that also provides phantom power. This adapter will allow you to connect the XLR microphone to the 3.5mm input while ensuring that the microphone receives the necessary phantom power for proper operation.
Unless they have a battery built in, if it's a pro condenser microphone with an XLR cable and it doesn't have a special funky power supply just for it, turn on the 48V phantom power. It won't work otherwise. Dynamic mics will ignore phantom power generally.
