I remember using a modeler a long time ago, spending days to find the ultimate tone - I was happy - a HUGE guitar sound.
Then a friend of mine came with a Mesa Boogie - turned some knobs - and we wanted to make some music together.
I heard his sound - and thought - not to bad - but nothing compared to my HUGE sound.
We started to play both at the same time - and used a backing tape with drums & bass.
The Boogie sounded great and cut thru the mix - my "HUGE" sound was not there at all
Then I learned the art of a great guitar sound - it's NOT the sound which sounds HUGE when played solo - but the one which sounds great in a mix.
