There is no such thing as cheating when it comes to guitar tone! Too many musicians let what other people say effect how they deal with guitar equipment.
Some great tones have been done with pedals, not so great tones have been done with pedals, but overall you look at most professional musicians board and YOu will see at least one or two different kind of OD or distortion pedals. In the end if you can get great tone out of a little OD box then what do you care? Guitar is not a club where you can only do things one way!
Musicians that I know of that use pedals
Timmons
Via
Satch
Cobain
ALmost any 60's, 70's or 80's artist
Almost anyone that plays a dual rec these days uses some OD to boost the preamp
On my RK1 I love to use teh brit mode, I max the treble, gain, leave bass and presense around 12 noon and slam the front end with a ibanez TS9 with the gain and drive maxed, you want to talk about a great vintage marshall vibe!
