Do guitar amps have preamps?

A guitar amp is comprised of two main sections; a preamp and a power amp.
 

Do I need a preamp if I have an amp?

Yes, you need both.



A power amp expects a signal at line level; a preamp is needed for that. You could technically go from a preamp, straight to active speakers without an external dedicated power amp. But, only because active speakers have built-in power amps for each driver. It wouldn’t work with passive speakers.
 

Can you use a normal amp as a preamp?

Yes, if the amp has a preamp output then that can go into a power amp. Without that, you need an expensive go between to convert a speaker output into preamp level or DI level output, often called a “power soak” feature.

Do electric guitars need a preamp?

A preamp is an important part of the signal path for microphones and certain instruments, like the electric guitar. If you’ve ever plugged a microphone into an audio interface, or an electric guitar or bass into an amplifier, then you’ve already used one.
 

How do I know if my amplifier has a preamp?

If you’re not sure, look on the back of the device. You should see a label that says phono, with a ground screw right next to it. If you do, it has a preamp. Most new models of amps and receivers don’t come with a built-in phono preamp, but they may have a label that says phono anyway.
 

Do you need a guitar preamp?

A DI or preamp is essential for getting the best sound when plugging a guitar into the mixer of a PA system, and many guitarists prefer to use a preamp even when plugging into an amplifier. Some preamps can also route your guitar to multiple locations.
 

When should you use a preamp?

A preamp is a unit that amplifies a low-level signal to line level; that’s the primary function. It comes after your microphone/instrument level signal and before your interface or outboard gear.

Do I need an audio interface if I have an amp?

An interface is a device for connecting audio sources like mics and guitars to your computer and your computer to speakers and headphones.
