Guitars frequencies question

[Blor007]

Hi

I read an article (some time ago)
which said that Marshall cabinets roll off at about 5000hz.

Now if I do a frequency spectrum analysis I can +- witness this downwards pattern,
but in commercial recordings the guitar has full spectrum untill 16k where there has been done a roll off ?!


Any toughts?

Your amp puts out way more high end than your speakers produce. They work together. If you plugged the guitar amp into a full range speaker, like a stereo speaker, the high end would peel your face off.

k...

And how do I capture those high frequencies?

 

[Farview]

You stick a mic in front of the cabinet.

As a simple reference, the A string on the guitar is about 110 Hz. The E String about 330. High E on a 24 fret guitar would be about 1300 Hz

If an amp produces to infinite hZ but the cab produces to 4k and then rolls off. If you stick a mic for the 4hz the amount of 10-16k the cab produces + what the mic captures is minimal and thus not enough :s

ummm...come again?

Have you ever stuck a 57 in front of a guitar cabinet?

5k is the 3db down point when tested with pink noise. This has nothing to do with real world, guitar amp performance. It all works out and is part of the sound of an electric guitar. If the guitar sounds muddy, turn up the treble on the amp.

Left is my guitar
Right is the guitar from Foo Fighters - All My life

As you can C I have a huge gap

I used on-axis mic SM57
Gyraf Gyratec Pre-amp
Mesa Boogie Dual rectifier : Treble -prescence at max , bass very low.

And I already listened for the most treble sound I could find, and It just sounded awfull. It also is the number one mistake (I read that , not sure, finding it out now )

Your ears are shot. Quit looking at the sound and start listening to it. If it sounds like shit, keep dialing it in until it sounds better.
