Amp Tone and Effects Placement
"Tube amps sound good"
"Solid-state amps sound bad"
Try to play tube amps near their saturation point -- this brings out the power tube sound and engages the guitar speakers. To play quieter, use a lower-power tube amp such as 5 watts. Strive to bring out the physical, real, tangible tone of saturating power tubes and hard-driven speakers. This includes using feedback, room noise, room reverberation, and hum and buzz. Clinically sterile tones such as a guitar effects processor and "speaker simulator" (treble-cut) recorded straight into the mixer sound cheap and too convenient and easily reproducible.

This database is only a collection of user comments right now. Keep in mind that you are reading people's opinions here, but
your opinion is the most important! You should not use these comments to decide which amp you should buy - Use them as
a starting point. They can point out some issues that you may want to think about before heading into the store. Use them to

The Cool Sound of Tubes - A technical discussion from the electrical engineering journal, IEEE Spectrum.
|Although solid-state technology overwhelmingly dominates today's
world of electronics, vacuum tubes are holding out in two small but
vibrant areas. They do so for entirely different reasons. Microwave
technology relies on tubes for their power-handling capability at high
frequencies ["Tubes: still vital after all these years," Robert S. Symons,
IEEE Spectrum, April, 1998]. The other area--the creation and
reproduction of music--is a more complicated and controversial story.
The complications and controversy stem from the fact that music is played to be heard by human beings, whose nonlinear ear-brain hearing systems are far from fully understood. Since no one knows exactly how to model the human auditory system, no one knows exactly what engineering measurements are appropriate to evaluating the performance of audio equipment. A smidgen of some kinds of distortion may sound worse to the ear than larger amounts of other kinds. So ultimately, the only way to judge audio equipment is by listening to it. Hence the controversy: subjective human perception--especially when flanked by questions of artistic merit--is made to order for arguments and disputation.

Tubes vs. Transistors -- Is There an Audible Difference?
Engineers and musicians have long debated the question of tube sound versus transistor sound. Previous attempts to measure this difference have always assumed linear operation of the test amplifier. This conventional method of frequency response, distortion, and noise measurement has shown that no significant difference exists. This paper, however, points out that amplifiers are often severely overloaded by signal transients (THD 30%). Under this condition there is a major difference in the harmonic distortion components of the amplified signal, with tubes, transistors, and operational amplifiers separating into distinct groups
