1 1 1 bronze badge. Here again, the short answer is that power amp distortion derives from overloading/distorting an amplifier’s power section. Another workaround here is having multiple amps and knowing which amp is appropriate for a given setting. On some guitar amplifiers, if you crank the master volume and strum a big huge A chord, that big chord is just like the refrigerator coming on, which is why you may hear that smoothing squishy compressed sound right when you first hit a big note. When the refrigerator turns on, it temporarily puts a large load on the system all at once, and the system will take a moment to pull more current to accommodate this new load. Some players prefer this sound, and this is why some amp designers create amps with sag in mind. 2. Distorted or static sounds - or complete loss of signal. When an amplifier is pushed to the right part of the power amp ‘brink’ we begin to hear and feel that classic BARK.

Many players will choose an amp with a high wattage power section simply for the clean headroom it provides, and will then rely on various pedals to produce a range of distorted sounds. Once we understand the differences therein, we can use this knowledge to master our amplifiers and adapt to many different playing environments. Many modern amps, and specifically high-gain amps, are fitted with a preamp gain control as well as a master volume control.
At the beginning of it all, when our tone heroes were doing all the work for us, the ‘Rock n Roll’ sound was essentially defined by power amp distortion. One day you arrive at a venue, you’re in the middle of soundcheck and the sound guy asks you to turn down, what do you do?

As an example, let’s say you are partial to power amp distortion and are therefore forced to turn up your amp’s master volume while keeping the preamp gain relatively low. Rig Rundown: Deep Sea Diver's Jessica Dobson, 1. A benefit to this is that most vintage amps are of somewhat lower wattage, so the interaction of the preamp and power sections can allow for some desirable tonal benefits without the amp having to get overbearingly loud. All rights reserved. The preamp gain control is essentially the first volume control the signal sees in the preamp, whereas the overall signal amplitude that is sent to the power amp by the preamp, is controlled with the master volume knob. If you connect your preamp to the phono stage of your amplifier, the signal is treated twice, thus you might get a distorted sound.
Again, lower wattage amps can still achieve that perfect level of power amp distortion while being plenty less loud than a giant 180W monster.
5 Reasons Why Speakers Sound Distorted 1.
If you hear one then the cable may have a short somewhere down its length. If the signal being sent from the preamp to the power section is of too high amplitude for the power amp section, the clean ‘headroom’ of the amp will be maxed out, and the user will begin to hear what is known as power amp distortion.

Vinyl Music On Bluetooth Suitcase Turntable Review. Distorted or Static Sounds. Master volume controls are typically used to manipulate this part of the signal, and this is typically the knob we will turn when the sound guy inevitably asks us to turn down.

One function is to attenuate the signal passing through the preamp section, and as a result of the level of said attenuation, the power amp will either be pushed more or less once the signal leaves the preamp and goes to the power section. The preamp is where the guitar’s signal is taken from a rather weak and anemic little thing, and boosted to line level.
Since the dawn of the tube amplifier, there have been countless heroes of tone; those who, both on stage and on record, we have all looked up to and even attempted to emulate.
