If it's just fat and/or controllable effects levels of effects -
in the mix, - then copy->paste works great. You have a clean tone, usually kind of "flat" which really means "scooped mids" because in the post-1950's history of electric guitar, most of it has been through systems that had a huge emphasis on midrange. Play your guitar through a PA with tweeters or horns, you'll see... :evil4: And, on the other tone you pile in some overdrive, and cut the screeching highs and mud-filled lows. It's actually a really good idea to experiment EQ'ing the signal for bass and treble cuts
before it hits an overdrive - you want to try all the variables in signal path, eventually.
From my reading of interviews, I'd guess that over half of touring guitarists now used a bi-amped system live. If my memory serves me, I believe it was Steve Morse who began playing through two (or three) amplifiers on all the time, then it quickly spread to his bud Eric Johnson, who passed it on to his bud Alex Lifeson, then BLOOEY! all over the place. The usual setup is to have a Fender Twin or such to produce clean highs and lows, and a Marshall-y amp set for midrange overdrive. Overdrive sounds best in there, and if you try to overdrive a clean amp, the bass frequencies load up a disproportionate amount of the signal. Which is why rack compressors have a hi-pass filter, to keep the bass spectrum from hogging all the juice. No two-channel amp can do this, it takes two amps. I
believe the latest PODs will let you run two separate paths. I used to use a rack system with a split signal, clean and dirty with different EQ curves, a poor man's way to duplicate this.
So anyway, yes, copy another track of a solo, then pull it out, cut the lows and highs, then dirty it up and add it back together. See whether you like it, try it some more. There's some real fun things you can do with your clean, "stringy" sound up loud and a super-cranked out pile-driving fuzz-sounding tone mixed back in - but very
faintly. It adds, like, FUR to the BEAR - but without taking over. I love mixes that add faint, odd, nearly-hallucinated stuff mixed way back - "Paul IS dead...." :toothy12:
