@alisynthesis @samvarma Capos are basically "intonation ignorant" devices. When you have a capo on, and then fret additional chords or notes above it, you are fretting the string in two places, putting an extra stretch on it which makes it go sharper compared to playing those notes without a capo.If you have a keen ear that is sensitive to intonation, you will find yourself fiddling with the tuning to try to compensate for what the capo is doing, and then have to undo that when it comes off.If your guitar has bad intonation to begin wtih, it will be even worse.
