Guitar as an electric signal source, guitar pickup's characteristics.
Guitar
with pickups produces electric signals according to vibrations of
guitar strings. The signal quality and properties depend of type of
pickups and many other conditions. But pickups produce electric signals
for further amplification and processing so I explain it in details.
Single Coil Pickup: Old
Fender pickups are single coil units. This compares to Gibson, which
started using double coil (Humbucking) pickups in 1957. Single coil
pickups have a single slab of wound wire around magnet(s). Single coil
pickups are easily influenced by outside noise. This would include
60-cycle hum and fluorescent lights. Signal noise ration for this type
of pickups is around 65..75 dB.
Humbucking pickup:
This type of pickup has two single coils combined into one unit. Each
coil is reverse wound so that the hum from first coil cancels the hum
from the second. Signal noise ration for this type of pickups is around
75..85 dB.
The longer the pickup wire and
more turns used, the higher the resistance. Also the higher the
resistance, the louder or "hotter" the pickup. But be aware, higher
resistance comes at a cost: lose of treble frequencies. This is why
single coil pickups have more treble and less output than Humbucking
pickups (which use two coils). Hence Humbucking pickups have more
mid-range and are "hotter". Also this is why single coil pickups that
are wound with tons of wire (to approach Humbucking ohms) don't sound
very good.
Usually pickups have the
resistance around 5..9 kOhms and produce electric signals around
0.1..0.5 Volts. Both resistance and output voltage of guitar pickups
are not very bad for microphone or line input of ordinal sound cards.

How do Guitars Monsters make their great sound ?
Usually
they use the typicall set of audio equipment. As a rule it consists of
a tube pre-amp (ADA), analog solid circuit distortion box (Ibanes Tube
Screamer or SansAmp), power tube amplifier (Mesa Boogie, Vox,
Marshall), special guitar speakers (Marshall, Celestion) and microphone mortgage quote (Shure 57 etc.) placed in front of the speaker. All parts are
essential.��������� ������� �������It is very important to note that guitar signal never
is recorded directly from pre-amp or power amp output, but always from
microphone.
DigiTech XMM Metal Master™ Heavy Metal Distortion Pedal
For the meanest metal imaginable! Levels of grinding gain and singing sustain previously unattainable without the use of powerful tube amps at high volume. Hybrid tube/solid state distortion circuitry gets it all, from subtle overdrive to extreme saturation worthy of the blackest metal. Three-band equalization with a parametric mid to cover the sweet spot between 200-5kHz allows for a range of brutal tones, including the scooped mid sound of Metallica or Pantera. Where other distortions aren't enough, this kills.
Features: Hybrid tube/solid statge distortion circuitry
Three-band equalization with parametric mid control
Anonymous enthusiast wants to share excitement about finally discovered secret of elusive warm guitar tone he has sought for years. He has tried all sorts of rackmount preamps, power amps, effects units, combo amps, and so on. He has finally found the secret to a warm guitar sound; this may help others looking for the same classic warm guitar crunch and long, smooth sustain!
The sound of this set of audio equipment is more of a straight rock sound like old Van Halen, Yngwie Malmsteen, George Lynch, AC/DC, and so on, rather than the modern highly fx-processed sounds of players such as Steve Vai, Satriani, and Petrucci. Of course you could add any effects you wish at the console.
The last time I used a distortion [overdrive] pedal was on Ride the Lightning, and it was hell. It was an Ibanez Tube Screamer like Kirk uses. It really helps his solos cut through, but it puts a shitty coating on smooth rhythm tones, and it was hard to make it not sound like a pedal. You can recognize Marshall distortion in an instant; that's why I shied away from that and went with MESA/Boogies. I basically use the Boogie's distortion with a non-programmable studio-quality Aphex parametric EQ to fine-tune certain frequencies, dipping out some of the midrange. All my speakers are Celestion Vintage 30s."
Metallica is the cover story for Guitar Player Sep 1991, which I have. James: "I use a lot of mics... up to 8. I use them to phase-cancel each other, to control the sound like with an EQ but instead of an EQ. ... for the 1991 album, I'm using MESA Boogie amps, with ADA MP-1 tube preamp, but Boogie Simul-class II is the main part of the sound. Cabs: Boogie for clean, cutting stuff, Marshalls with 30 watt Celestion Vintage 30s for warmth."
Hardware Digital Audio Effects & Guitar Processors
Rocktron VooDu Valve™ - Tube Guitar preamp plus Digital Processor Sound Example
Digitech, BOSS, DOD, Roland and, may be, Zoom are very good looking things. Guitar Effects Processors have great functionality if you believe in words that manufacturers and magazines like "Guitar Player" are saying! But you understand they are advertisement words only. Note: Professional guitarists use Guitar Effects Processors not very often. Why? The real sounds from the devices are far from advertisement in guitar magazines. At the same time, why we can't find WAV or MP3 files with sound examples of such devices. I have scanned hard Internet and failed to find them, but I have found a lot of sound examples from different analogue solid state (transistors) and tubes based pre-amps, power amps and distortion boxes. Some famous Guitar Effects Processors use analogue and even Tube pre-amps and distortion sections!
Rocktron Prophesy Tube Guitar Preamp with Digial Effects
So, the digital part of these devices makes (as a rule) chorus, flanger, delay and reverb, and sometimes pitch-shifting. Experts often say that special studio hardware digital Reverbs produce, as a rule, better sounds. But, modern Guitar Effects Processors implement (in digital domain) several guitar sound related things. The most important are tube pre-amp, power amplifier simulators, guitar speaker simulators and, sometimes, microphone simulators. It seems to me that these things could improve guitar processors sounds. But Guitar Effects Processors with such simulators cost like the best tube pre-amps and tube power amplifiers with excellent guitar speakers.

Sound Cards for guitar signal digitizing
Sound cards for digitizing guitar signals
must have very good signal to noise ration (SNR). SNR of analog-to-digital converter (ADC) of sound card is the most important technical characteristic in our case. It must be 24 bits 96 kHz at minimum.
A soundboard for all reasons!
Based on EWS88/MT/D technology it supports any software with ASIO 2.0, GSIF, or DirectSound drivers. The most demanding applications are supported with 24-bit/96kHz resolution and distortion separation of more than 101dB. With all the standard features of ordinary soundcards, it also gives you a MIDI connection.
The EWS 24 bit/96 kHz comes with the following software:

Ask yourself why you plug your guitar into effects pedals, boxes or stompboxes?
The answer is you want to have a great sound. You are dreaming about power impressive distortions
like Metalica has and natural sounding 10 sec sustain like Santana guitar sings!
During XX century guitar players have known one way only - to buy expensive pedals and stompboxes and
plug a guitar into a hole in these devices. But times have changed.
Today all we have got personal computers (PC). I am sure many guitar players with PC have seen several
holes at the back side of their PCs. These holes look very similar to the holes on the effects pedals!
So, many of us sometimes think -
I have pluged my guitar into effects pedals during last 10 years.
But now I would like to try something new. Well, why (at the end) do not try
to plug in a guitar into PC? What happens if I put my guitar cable jeck
into one of the holes at the back side of my personal computer?
The answer is you will get a great guitar sound! Yes, your PC can
pumps electric guitar signals, processe it, apply distortion, sustain,
wah, chorus, flanger, reverb, delay effects and output result signals on your
headphones or speakers.
PC doesn't need in additional equipments to do this. No options necessary!
(I am sure your PC has a sound card).
How to do it?
Usually, we have "big jeck" or 1/4" jeck at the end of a guitar cable.
At the back side of PCs usually we can see 1/8" holes. So, you need to buy in nearest computer or music shop a 1/4" to 1/8" adaptor.
It costs around $1..$2. Then you can plug in your guitar into the blue color hole at the back side of your PC.
Usually this hole has "Line" title. Don't forget to plug in your stereo headphones into black color hole (with title "spkr")
at the back side of you PC. Now you can tune your sound card audio mixer. Go to the Windows 95/98/2000/XP "Sart" menu at the bottom right corner
of PC screen, choose "Run" option, type "SNDVOL32.EXE" and press "O'k" button. You must see a picture like you can see in
this article.
Set up all slieders exactly in the same positions as you can see in the article.
Now you are ready to get some for free software from my site, install and run it.
Now try to play something on your guitar and you hear that your personal computer works like the best traditional effects pedals or stompboxes!
You must know that you can find in the Ineternet hundreds titles of free audio effects softwares for your PC.
It means you can enjoy with the best world distortions, sustains, reverbs, choruses, flangers, delays, equalisers, tube amp simulators
realy for free using only your personal computer!

The World's best amp modeling Guitar Effects Processor must contain and use only the World's best effects and tube amp models!
It's impossible in the hardware (stompbox) world. Modern hardware guitar effects processors
contain only those effects and amp models developed by a single firm. Some firms can develop the best reverbs (say Lexicon),
but another firm can develop the best flangers (say DSP-FX) etc.
If you want to have the best guitar effects processor in the world you must be able to construct your own
using effects and tube amp models that are the best in the world. This is now possible by using the best software "fx building blocks" in the world.
Simply download these beautiful effects "plug-ins" or "fx building blocks" you can find on this site, then download any of free (or not)
fx players
and construct your own best guitar effects processor in the world!
Construction is simple. Run fx player, insert your chosen effects, connect the effects as you like and enjoy!
A typical effects chain is "Noise Gate" => "Compressor" =>"Distortion" =>"Equaliser" =>"Flanger" =>"Amp Simulator" =>"Reverb" =>"Microphone Simulator".
