^Fin nerdekunnskap om gitaren det der. Denne tråden altså
Litt tilbake til feedback. Her kommer en relevant artikkel fra Stereohile fra 1998. https://www.stereophile.com/reference/70/index.html
Artikkelen gjør ett dypdykk rundt erfaringer med mange ulike forsterkere, med og uten bruk av feedback, og nevner også en blindtest fra syttitallet med mange av datidens storheter. Det er også verd å få med seg "letters" seksjonen sist i artikkelen.
Noen få utdrag av teksten (advarsel om subjektive greier):
When the results of the blind test were analyzed, the tubed Radford had come in first, despite showing the poorest measured performance.
Some engineers have been developing an awareness of how we've gotten some of it wrong. Glimpses of audio heaven have been observed and reported with a number of exotic single-ended creations. More precisely, the SE units' sound over the broad midrange---in point of fact, over most of the significantly audible frequency range---reaches a level of purity and intrinsic musicality that inspires near-religious fervor. Such quality shows the rest of the industry what they're missing.
Subjectively, the effect of increased negative feedback is generally that of increased compression, in addition to the midrange coloration noted above. This loss of dynamic expression suggests that additional energy is indeed filling in the natural spaces in the original spectrum and thus blurring musical expression.
