He's late on the scene, the latest fad is to give credit to digital sound, then find some flaw in it that "my special expensive woo woo box will solve" at the moment it's the need to syncronise a 10MHz clock between devices and correct the scew.

A Guitar Amplifier is an amplifier and speaker unit designed for guitarists.

It has EQ, gain, volume controls and a speaker that are designed to introduce distortion.

This allows a guitarist to add colour to their audio path and have high sound volume (Jimi Hendrix style).

A High Fidelity Guitar Amplifier doesn't introduce this distortion into the audio path.

A guitarist would introduce all the distortion effects given by a Guitar Amplifier (Marshall style) before it enters a High Fidelity Guitar Amplifier.

So, a Guitar Amplifier uses a high power, high distortion amplifier to drive a high power, high distortion speaker.

To get higher fidelity, the two issues to address are the amplifier and speaker.

The amplifier can be any off the shelf, high fidelity, high power amplifier.

The speaker in a Guitar Amplifier is designed to run in an open enclosure, giving maximum sound power output for a given electrical power input, but at the expense of distortion.

The speaker in a High Fidelity Guitar Amplifier is designed to be mounted in a sealed enclosure, where the volume of the enclosure is dependant on the Thiele and Small parameters for that speaker.

This gives a maximally flat frequency response from the speaker, but also means the speaker delivers half the sound power output for a given electrical power input.

From the Oxford, 'fidelity':

the degree of exactness with which something is copied or reproduced.
"the 1949 recording provides reasonable fidelity"

Building a web site from the ground up using a new technology like WebGL is a learning process.

It was a long and hard process to understand WebGL and use it effectively.

This web site is the culmination of twelve months of research.

An Electronic Workshop is a place to go and learn electronics.

If you want to learn WebGL, read the code.

If you want to learn how to build a High Fidelity Guitar Amplifier, go to my web site when it is finished.

Web sites don't drop out of the sky.

Mine will require years of development.

If you want to help me build a gaming style fast, responsive, interactive web site using only WebGL, then read the code, give me some advice, and share your knowledge with others.

If you want to learn how to use WebGL, ask me a question, and I can give you practical answers because I have practical experience.

That blank page is the result of 12 months of research? I suggest you grow up and use something normal as this website seems a bit Schrodinger to me.

If you are developing WebGL applications and want to copy, reuse and improve the code in it, then its not Schrodinger. Its Humdinger.

I'm not sure I get the link between guitar amps and WebGL.

When I started my business, I decided that my web site would use only WebGL. HTML is painfully slow.

I am a sole trader and Electronics Enthusiast, and building and selling amplifiers, building web sites, and using WebGL, are all things that I am becoming more interested in and gaining more practical knowledge about.

I use this forum to teach, learn, and and share knowledge.
