You will have acquired the fundamental principles to your guitar and are generally enjoying a number of clean guitar chords, riffs and licks. You wish to study and try fresh sound effects either for song-writing or maybe performance. Your next plausible action is usually a guitar effects pedal or maybe multi effects pedal. These seem to be words that appear pretty self explanatory, then you're met with ‘Digital’ and ‘Analog’ effects. Consequently, I figured I will get out there and uncover what the distinctions were to ensure that my own misunderstandings might stop, at least prior to the next geeky piece of jargon comes my way… I only want to make music!
Hopefully, my research will also help you and by not having a physics degree I can put it in terms we can all understand:
Digital means that the signal from the guitar is initially run through an analog to digital (A/D) converter that will translate it into a digital signal (meaning a series of 1's and 0's - binary code?). The effect device then performs some computations on that digital signal, changing it. Therefore, it acts just like a computer; in fact a digital effect is just a computer with the specific job of producing sound signals. The transformed signal next runs back again through the D/A converter ahead of being output with the audio unit. Furthermore, an electronic digital effect system might be developed to deliver virtually any sound.
Following the description for Digital, an Analog effect means that the transmission is actually processed like it is, with not much interpretation prior to or following, although it sometimes might be run via a buffer guitar amp. Hence, the analog effect happens to be an electrical circuit which does a little something using the transmission which is produced by a guitar as a result of the dynamics of the components.
Genuine Analog effects are by and large thought to sound more natural plus some consider them to have, generally, a higher quality. Though, several higher level digital effect units do a really good job of impersonating well-known analog effects like distortion and delay. Interestingly, Analog delay used a reel of tape that was constantly being written on and then erased. A sort of hiss then took place. The digital delay effect is going to be as crystal clear on the first recording as it would be after 100's of rewrites. This may be seen as a positive or negative depending on your personal preference.
Both digital and analog effects have completely different circuitry in the pedal that is producing the effect and one certainly is not better or worse versus the other. As with all things musical, only your ears can choose which you like. A digital effects unit, sometimes known as a multi effects pedal or rig can provide you with the benefit of the ability to produce many of the sounds available in just one piece of equipment. Additionally, there are a few effects like a Harmonizer (adds a harmony note to your playing based on a chosen scale) which are unobtainable through analog, and therefore digital guitar effects pedals can certainly reach the places that other analog pedals cannot. To sum it up, you'll find good sounding and inadequate sounding analog effects and also by exactly the same reasoning you can find good sounding and inadequate sounding digital kinds. A few point out analog effects seem warm when compared with digital, however this might be as a result of far more restricted top frequency response. While a few state that digital devices possess a coldness that seems artificial or perhaps out of place which may be as a result of depth of effects obtainable. Some you win, some you will lose. In the end, it is just a question of preference as well as the particular result you need.
Nowadays, digital is employed a lot more since the price of the circuits reduces. Most multi effects pedals are digital. Something for sure though, if you look around the options are staggering.
