I agree with most of what's been said here but I still might get stoned for this post.
Well actually I've had good luck a) playing in a 3 piece where you don't have to fight as much for tone space - still have to take care to have a good bass tone live that fits with the mix. And b) cutting back the amp clutter on stage, going with Pod XT Live's into PA gear.
So obviously I see some need for frequency slotting but is there a possibility of overdoing it? Jumping blindly on the frequency slotting band wagon and missing some of the effect you can achieve with a little overlap in places? Why else would orchestra's have 5 or more Cello's, 5 or more Violin's etc... (ok for volume originally being one reason)
I've been a sound man as well and have found there are times when the sound is richer with a bit of overlap between the guitar and the vocals (clean high guitar, alto/tenor vocals) - I know this isn't in the coveted muddy mid range - but it illustrates the point.. there's this "don't touch his frequency" law being applied to EVERYTHING in the whole spectrum but isn't there a time and a place to overlap a bit?
I've mixed bands with 2-3 guitars where some tunes are going for that power chord wall of sound feat with lead, rhythm and bass all playing the same riff. The guitars sometimes definitely overlap but the mix was good enough that it made them sound "thick" and not muddy.
So in professional terms, am I right? Is frequency slotting a golden "guideline" that has certain times the rule should be bent a little to achieve certain sounds and feelings in the music? Or is it an end all be all policy that must be adhered to OR ELSE!?
One song I'm recorded on has some particularly high bass along side some particularly low guitar... and it sounds great. Versus those who tell bass players they'll cut their strings if they play anything above the 7th fret. (Heard a guy actually say that, not to me thankfully)
So sue me... I have great tone.
