How to Use the Effects Loop on Your Guitar Amp (And Why You Should)

This post may contain affiliate links

Have you ever gotten a new guitar amp and found a pair of strange jacks on the back labeled “Effects Loop” or “FX Loop” – With one jack labeled “Send” and the other “Return”? Chances are: you have. And chances are: you may not be sure exactly what to do with them.


It is not uncommon for people to just completely ignore this part of their amplifier because it is not a requirement to use your effects loop, however, using the effects loop on a guitar amp can greatly benefit your overall tone. 


But what is it?


What is an Effects Loop on a Guitar Amp?

The effects loop of a guitar amplifier is a tool that allows us to place effect pedals after the preamp in your amplifier (where your amp gets all of its tone) but before the power section (where your amp gets all of its volume). 


Think about how you organize your guitar pedalboard. Overdrives and distortions first, then modulation, delay, and reverb. You will almost never place a reverb or delay pedal in front of a distortion pedal. However, your amplifier typically adds a bit of overdrive or saturation to your tone. So if you are putting reverb and delays into your amp’s main input (like most people do) it effectively like putting a reverb pedal before your distortion. This can end up making your amp sound muddy and less precise.  


The effects loop allows you to put pedals like reverbs and delays after your amplifier’s natural distortion. 


Do You Need to Use the Effects Loop on Your Amp?


If you have an effects loop on your guitar amp, it is honestly worth trying. It is very easy to set up and usually sounds good!

If you are a guitar player that uses their guitar amp’s “drive” or “distortion” channel, then using your effects loop may improve your tone quite a lot. 


If you usually use the “clean” channel on your amp and use distortion pedals for grit, then the effects loop may not be as useful, but you should still give it a try!


What Pedals Go in the Effects Loop?


Typically, you will want to put modulation and time-based effects in the effects loop of your amp. Definitely reverb and delay pedals, and sometimes modulation effects like chorus or flanger pedals. These are the types of pedals that will benefit most from being placed in the FX loop. 


To do this, you just need to break up your pedalboard into two sections. 


The first being the non-effects loop section containing your overdrive, fuzz, compressor, volume or wah pedals. This section is wired up normally: Guitar into pedals into your amp’s input. 


The second section is your effects loop section. This section, as explained above, will include pedals like your reverb pedals, delays, and (sometimes) things like chorus and flanger pedals. To wire these up, you will take an instrument cable from the “Send” jack and wire it to the input of the first pedal in the chain. Then you will take another cable and wire it from the output of the last pedal into the “Return” jack. You have now placed these pedals between the preamp and power sections within your amplifier!
