The story of the first amplifier ever
The first amplification systems capable of extending an audio signal effectively were used mostly in cinemas and theaters, given the bulky size that characterized them. It was in 1927 that these devices were finally able to do without the large batteries that made them work, starting to interest musicians who, gradually, would make more and more use of them in their concerts. Thus was born the Public Address system. To date, it is particularly difficult to draw a line between the first amplifier in history and the first hi-fi systems, often selected as favorites even by guitarists. The first examples of amplifiers, moreover, did not have equalization controls or distortion effects and, moreover, were characterized by a fairly low wattage.
We can consider the amplifier produced by Stromberg between 1928 and 1929 as the first in history. It is a device built specifically for the amplification of electrified stringed instruments. We are talking about a very rudimentary example that soon fell into oblivion as it was heavy, expensive and inefficient. In 1932, Electro String Instruments developed a magnetic pickup capable of detecting the vibration of strings rather than woods. An amplifier was put on the market compatible with the new prerogatives of the market, at a more accessible price than previously experienced. In 1934, the Rickenbacker brand produced the model; laying the groundwork for what brands like Fender, Gibson and Marshall, among others, would make iconic in the following years.
