This outputs line level audio so you would need an amplifier to drive a speaker. Any amplifier that accepts line level would work.

This works great for amplifier troubleshooting and testing. The variable output level lets you dial it down to instrument levels and it can also do line level if you need to jump signal in past the initial preamp stage.
