If you are a budding guitarist, you would have struggled to know the difference between the gain and the volume.
You might have even questioned its importance. In simple terms, the gain is your input signal and volume is your output signal. Using game, you can find your own especially when you move up in sophisticated amplifiers with more Complex circuits.
A guitar amplifier has two stages. They are the preamp stage and power and stage. The Preamp stage is responsible to take up the original signal from the guitar and process.
This will help in giving you a better tone and timbre. While the responsibility of the power amplifier is to give the output volume and push it through a speaker. So gain is a function of the preamp stage. It will manage the strength of the signal.
You can even call as an input volume level. It is very important as the input volume level will help you in determining the voltage to be sent in the tubes.
With the help of the gain control, you can induce distortion into the signal and play low volume by using the volume control. The final output is the function of the volume control. So volume or gain is both essential for a fine pick up of sound.
Gain and volume knob on the amplifier
Most of the amplifiers these days available with gain vs. volume control. A sum of the amplifier gain control is called a drive. However, the gain is the electronically accurate description of the function of the control.
When you turn on the gain control, physically turn up and drive the tube and transistor order to reach a point of saturation or distortion hear the independent volume control will help to govern the output volume.
Using this you can simply turn down the volume. It does not affect the distortion level as the control is there with the gain control.
If you have come across guitar effects pedals, you would have seen the notification of the game for drive control. Overdrive and distortion pedals will have three essential knobs. They include the drive the tone and the level. The drive knob can control the distortion adding to the sound.
The level of controls tells how much overall volume the pedal must put out. This will hit the front end of the amplifier harder to make it louder very quickly. The tone is very simple as it will bring out the higher end of the sound when turning to the right.
