If the guitar's intonation is set up correctly, you should not have to fine tune with the capo on. One thing to note: place the capo directly on the fret. Yes, you read that correctly. I have been placing the capo right on the fret - basically splitting the fret with the edge of the capo's rubber part for over ten years.. There are certain capos which cannot be used this way, due to the way they are made, but one with a straight, sharp leading edge will work perfectly. I can prove that it works. Kysers, Planet Waves, Fender pressure type (no screws,) most Dunlops, Shubbs - all work. As for the OP - yes, I use capos all the time. Standard capos, cut capos, both together - whatever it takes to get the sound of open strings I'm going for.
