One guy on internet demystifies “guitar amp tone”, showing it almost wholly concerns EQ settings and internal circuitry

(( Do not miss the microphone comparison, speaker cabinet comparison, string comparison, etc linked at the end of this post, which are all equally revelatory. )) From video comments — ”I am just a performer, I know nothing about circuits but in one summer I reversed engineered the whole guitar industry and made it open … Read more

Mark Devlin on The Great 20th Century Music Con

160,000 watts of RUSH — how loud is that, really? Turns out, only about 8 times louder than a 300 watt amp! And only about 16 times louder than a 30 watt amp!

The mention of one-hundred sixty thousand watts, holy cow, that’s huge! actually breaks down this way: Every doubling of power is represented as 3 dB, but it takes 10 dB difference to make something sound (to most humans) “twice as loud” or “twice as quiet”. So 160,000 watts sounds only about twice as loud as … Read more

“I don’t always listen to Journey, but when I do so do the neighbors.”

Steve Smith.. never one lick out of place. Ross. same. Jonathan… just solid and a perfect match for the band Nothing flashy. Neil… fiery solos and aggressive playing but … Read more

Contribution of active hair-bundle motility to nonlinear amplification in the mammalian cochlea

Abstract   The cochlea’s high sensitivity stems from the active process of outer hair cells, which possess two force-generating mechanisms: active hair-bundle motility elicited by Ca2+ influx and somatic motility mediated by the voltage-sensitive protein prestin. Although interference with prestin has demonstrated a role for somatic motility in the active process, it remains unclear whether … Read more

Electron Movement through Solids – Energy Bands and Semiconductors

Materials vary greatly in their ability to conduct electron flow. A digitalization may take place that has bearing on sound quality and overall performance, fidelity and response. https://www.youtube.com/watch?v=KYYWZhsgVPc   Electron movement through solids is a fundamental concept in condensed matter physics and semiconductor technology. In a solid material, such as a metal, semiconductor, or insulator, … Read more
