Here is the easiest and cheapest way to amplify your guitar and maybe do some karaoke-style singing. On this Sunbuck TAV-6188E amp, you can connect your electric guitar and microphone at the same time and even use the built-in Echo or Delay effect.

In this video, I even try to connect the NUX portable Bluetooth amplifier via headphone out directly to MIC input and it works too. You can even connect to the LINE input behind the Sunbuck amplifier which will result in much better sound and you spare one MIC input.
