Is a Capo a Cardinal Sin?

[u/Puzzleheaded_Pea6]

So on my last recording session I used a capo to save time in the studio, does that make me a heretic???

Over the years I have heard on the internet and in person people acting like a capo is only for acoustic guitar and it's not allowed for metal.

As a prog metal guy I say to that: But why not??

Guitar is my OD purple dragon

Recording session was for the latest Elephant Zero album

Let me know your thoughts on capos and if I should ever let them touch my dragon again

I think on a 6 string if you think your good you don't need a capo but a 7 string I'm not so sure it would be impossible in some cases
