Nigel: I was referring to the guitarists habit of driving every amplifier into distortion mode. If they do this with a class A transistor amp, I'm sure they wouldn't like the sound.
I didn't ask my friend about songs made with a class A transistor guitar amp, as you said, there are none. He will reply with a list of songs made with class A valve amps. However, if cracken says he does not wish to examine some class A guitar sounds, I will stop this apparently intrusive and unwelcome contribution.
audioguru said:Distortion is high frequency harmonics. But most guitar musicians are deaf to high frequencies.
Brian May (Queen) Only plays a stack of Vox AC-30's
Definitely!So you assume that all of us rock n' rollers here are "old geezers"?
Definitely!
The Beatles (I know they were not rock but were pop instead) were on TV a couple of nights ago. The picture was in black and white, the distortion was awful and the frequency response stopped at only 3kHz. I heard it the same on my AM radio about 47 years ago (!).
AC/DC tone:
I hear square-waves from the over-driven guitar amps and screaming from the "singers". It is noise, not music.
I am not a guitar player. I like listening to non-distorted live and recorded acoustic guitars, not the severely distorted square-waves from over-driven electric guitar amplifiers.
But I noticed that the recording you posted cut high frequencies above about 4kHz so it sounds like a lousy AM radio.
It is obvious that you are deaf to the high frequency harmonics of sound that is produced by severe distortion.
Jon Wilder said:Moreover, guitar speakers only work within the 70Hz - 5kHz range anyway...which is more than the usable pass band for guitar frequencies (82.41Hz - 1.32kHz at the fundamentals, leaving plenty of room for upper harmonics).
audioguru said:Your "70Hz to only 5kHz" is the awful muffled sound of an old AM radio. Normal people hear frequencies up to 20kHz.
You mentioned a Celestion speaker for rock guitar music. Did you see its horrible frequency response?
Nothing below 100Hz.
A null at about 1.5kHz.
A peak from 2kHz to 5kHz then a sharp drop above so that all the important high frequencies are missing.
It makes a sound like a muffled buzzer, especially when its amplifier is clipping. [/b]Real[/b] music has no distortion and has wideband frequencies.
audioguru said:Maybe you have never heard a recording of a symphony orchestra. It should have no distortion and have wide bandwidth. If your amplifier and speakers are good then it sounds the same as live.
audioguru said:An amplifier with distortion has a difficult time trying to sort out the frequencies and makes millions of harmonics that cause FUZZ.
A modern low distortion amplifier has no harmonics that are caused by distortion and has a wide bandwidth to produce the harmonics of the music. The high frequencies of the music "sizzle".
Correct.In regards to Celestions and their "horrible frequency response"...that is the sound of rock. "Horrible" is subjective...it's an opinion. It may very well be horrible for the music you listen to, but for rock they are the speaker to go with. Again...different strokes for different folks.
Correct.
Horrible sound is horrible. But severely distorted "rock sound" is worse.
