Let´s say you go to a place, visiting a friend or family, for example, or you´re with your friends and you ended up in an open mic bar, there´s a guitar and an amp, and you´re asked to play guitar.
My point is: There´s an X amp, with clean and high gain channel, and an X guitar. I mean, it´s not your equipment, but it´s what´s there.
How would you set a cleanish/crunchy sound and a heavy sound as quick as possible to start playing?
Is there some kind of basic set of rules to achieve that for an "emergency" moment?
I don´t know if I´m explaining the situation in a clear way.
Would you just turn the amp on, set everything to 12 o'clock - volume, gain, treble, bass, middle - and there´s your cleanish/crunchy sound, for example?
What would be your way to achieve this?
Off the top of my head I can think of Jeff @tonebender , John @toomanycats , John @tobijohn , Steve @BatUtilityBelt , Tommy @tlarson58 , Deeaa @deeaa , John @jtcnj , Aaron @RiverDog , @Rollin Hand , Rob @andrewsrea , Nate @honyock , @glasshand , Damon @nomadh , Enrique @Narsh , Randy @redman , but everyone is welcomed to share their 0.02 cents.
In short: How would you quickly set those two basic sounds? May not be perfect, but you need them just to perform in an unexpected situation (cleanish for the start of the song, crunchy for the middle part, and a heavier sound for soloing or the end, something like that).
This is my dumb saturday question
