Guitar Amplifier Trends
Author: guitartrends // Category: amplifier trendsIn the early 1950’s guitar amplifiers were low powered tube amps. These amps were louder than a big acoustic guitar, but only by a small margin.

As the 1950’s progressed, guitar amplifers became more powerful. By 1959, Fender was manufacturing the Vibrasonic and Concert models, both of which were rated at 40 watts RMS. Still electric guitarists wanted more power for some venues.
One outcome of this, is that players often played their amplifiers at or near full volume. At full blast, the sound from these amplifiers would suffer from distortion and compression. And players liked it.
In the 1960’s, amplifiers became more powerful. However, electric guitar players had already learned to play at high volumes, to induce the distortion and compressed sounds they craved. Public address systems were not as powerful and sophisticated as they are today, and therefore mic’ing an amplifier was not practical. So, you needed a powerful amp to play the gig, and you played loud to get the sound you wanted. Artists like The Who, and Jimi Hendrix are just two examples of artists who performed in this manner.

If you played in a band in the 1960’s or 1970’s, it was the electric guitarist who set the volume level which everyone else in the band had to match.
In the 1980’s guitar amplifiers began featuring a gain control, which would separately adjust the pre amplifer volumes. This meant that a guitarist could get his sound, without playing at full volume.
Those vintage low powered guitar amplifiers that were overdriven, and the introduction of the guitar amplifier gain control, has led us to smaller, less powerful electric guitar amplifiers.

Today’s smaller amplifiers are easier to move around, use less energy and still provide the amount of distortion and grind most players need.

Don’t forget the ‘59 Fender Bassman, which was the springboard for Jim Marshall’s designs.

Ahhh. The 1959 Fender Bassman. I had to stay away from that one, because I think it is worthy of a separate post entirely.
A good friend of mine is very well versed in electric guitar amplifier tube circuits. The stuff he was telling me about Fender and Marshall schematics really piqued my interest. I will follow up soon with a post about that iconic amplifier.

Well I think the increased popularity (and profitability) of Rock Music brought the performances to larger and larger venues requiring larger and more amplifiers. Individuals used more and more equipment. Mick Jagger commented in an magazine article that the large shows were really not very good until the P.A. systems improved and the sound improved so much via the P.A. such that the stage volume became more reasonable and everyone could hear each other much better (lower stage volume) I’m sure this resulted in a better more consistent sound. It seems these days a lot of musicians are using only mic’ed 100 watt amplifiers almost off stage and letting the P.A. carry the sound and monitors to let the musicians hear the sound. Certainly the skill of the stage crew has improved as much as the equipment. Just my opinion of course.

Thanks for contibuting Ron!
