If you’re a guitar player, then you’ll already know the importance that an amp attenuator has within your set-up and why you should have one in your equipment inventory. If not, you’ll find amp attenuators in the form of a value or tube amp and will be positioned between your power source and the speaker component of your amp.
The main purpose of an attenuator is to convert the power running through your amp into heat, rather than the energy turning into sound. You may be wondering why you would do this in the first place.
In short, instead of having to turn your amp down in volume, which can result in a weaker overall sound, an attenuator allows you and your audience to enjoy the full power of your amp, without the risk of blowing your eardrums when you play. However, finding an attenuator to convert this energy is easier said than done.
Of course, your top priority is making sure the tones and sounds coming through your app stay at the highest quality you possibly can. You’ll also want to make sure that the attenuator you choose can handle the power of your amp, no matter what that may be. To resolve this problem, you’ll want an attenuator with the highest power rating, since using a low-rating attenuator on a high-powered amp will damage both pieces of equipment.
To help you narrow down your search, we’ve looked high and low of the very best attenuators out there, allowing you to find the best one for you easily. From all we found, we managed to filter them down to our top four, so let’s dive straight in!

What we love about this attenuator is the fact that you can use it as an attenuator, connecting it to your power source and amp, or alternatively, you can use it as a load box, instead of using your typical speaker cabinet, allowing you to send a balanced XLR (or an unbalanced 1/4” line) to another app you may be using. This type of connection even allows you to send your guitar output to a mixer, perfect for recording your sounds during a live performance.
With this attenuator, you’ll be able to enjoy an incredibly superior sound quality, and thanks to the outstanding impedance, you’ll be actively protecting the lifespan and durability of your tube amp. There’s even an integrated 8/16-ohm switch so you can accurately match your settings to that of your cabinet and amplifiers, ensuring the best quality and a no damage to any of your equipment.
