That's why if you are interested in something you can usually watch multiple videos of it, including the ones filmed with an iPhone mic that look like the amp is in some cave in Afghanistan. Usually the professionally made ones are a better representation of the sound.Yup, this is a big reason why I find gear videos so useless.
"Here's what this amp sounds like!"
No, it's only what that amp sounds like in that very specific situation, being massively influenced by not least cab and mic sound.
