Thank tele-jas for the article link. You got me off the hook of scanning the GP article.
My niece download a virus on my computer which is hooked to the scanner that's why I could not scanned the article. Yes, I know, I could have used my other computer(s) but they don't have the scanner's drivers installed and I was lazy. My laptop is at my girlfriend's house which do have the scanner's driver.
O-kay I exaggerated "an enclopedia of Marshalls" but here's highlight excerpts from the June GP 2005 article aricle:
-"Clapton’s Blues Breakers snarl, Hendrix’s psychedelic screams, Gibbons’ grind, and many other fabled Brit-amp texures. In fact, it was easy for me to clone the sound of both a ’74 50-watt Marshall non-master head"
- The Crunch position adds another preamp gain stage to closely approximate a post-1975 master-volume Marshall model 2203/4’s higher-gain circuitry.
-For those who just can’t get enough JCM 800-inspired glory, Channel 2 begins by replicating Channel 1’s highest-gain Crunch mode.
