So, lately I see that my acoustic guitar goes a bit off tune when I use capo. Here is what I mean - I tune by guitar (say standard tuning) and when i put a capo on 2, the open base string shows slightly sharp G note, instead of bein exact G.
So, each time, I put the capo on a bar, i have to re-tune slghlty so it doesn't sound off.
I hadn't noticed the issue before and I have had the guitar for a while.
Does anyone know what the problem is? And the solution?
