Life too short for long YouTube videos? Please see the ‘Interesting bits and go-to sections’ information below.


In this episode we venture tentatively onto the thin ice of attenuators for guitar amps. It is a contentious subject, so here we are simply discussing the common approaches as an introduction to the concept.
THIS VIDEO IS NOT ABOUT IRs AND DIRECT SIGNALS. It’s simply about making your really loud amp a bit quieter through your cabinet/speakers.

We discuss the concepts of active and passive attenuation, reactive and non-reactive loads, resistive power soaks and voltage attenuation. We’re not particularly scientific about any of the technical stuff, so if you want to understand the physics, please hit up any number of websites, not least Wikipedia. Many of those pages will go into massive technical detail and you won't hear a single guitar tone. We're trying to do the opposite.

“But why didn’t you include //insert every attenuator ever available here// because I think it sounds much better.”
Good for you. Please make a video about it and educate us with sound.

• An explanation about the mic preamp volume changes you’re hearing in this video…
A sound needs to be at a certain level in your ears for you to hear it, enjoy it, and sound ‘good’ for want of a better word. That’s why mic preamps exist: to bring the level of the source to an appropriate level.
For example, a Marshall Plexi may be putting out 118dB (as a random number). Then you stick a mic in front of that, and set your mic gain accordingly.
Now turn the amp (or attenuate it) down to, say, 95dB, and you will perceive the sound to be weak, thin and quiet if the mic gain remains the same. Increase the mic gain, and it gets louder, fatter and fuller in the recording. With apologies for the technically basic explanation, that’s what Mick is doing in this video. As the amps get quieter and louder from the speaker, Mick is turning the mic preamp gain up and down accordingly to try to level out what the recorder is seeing in terms of input level.
To balance that, there is a visual guide to the volume in the room with the dB meter on the pedalboard. It’s not accurate - this isn’t science, but it’s at least a guide.

Enjoy the video!
