Yes you can. The guitar amplifier you end up buying will depend on your use case and preferences.
For practice and playing for a few friends, you would need a portable combo amplifier with 10-30 W power.
For rehearsals and small performances you would need a 30-50 W Amplifier generally a combo amplifier.
For live performance with a large audience you would preferably aim for a 100 W Amplifier.
You can also go for a separate head and cabinet configuration.
Other preferences that may matter,
- Type of Amplifier: Solid State, Tube Amps, Modeling Amps, Hybrid Amps
- Configuration: Combo or Separate Head and Speaker
- Speaker Size
- Additional Features: Reverb, Tremolo, Equalization (EQ), Digital Effects, Effects Loop, Channel switching.
We would love to know what's your use case for a guitar amplifier and other preferences.
