Thank you for the replies and pictures!
I ordered two classical guitar capos, as both of my classical guitars are standard, no-radius. Hopefully the first modification goes well, and I can use the second one maybe as just a standard capo.
It will be nice to use a capo to make fake DADGAD. Retuning classical is somewhat annoying because the strings need to settle, so retuning never ends.
If this mod is easy, I will mod my stand kyser. Or maybe I'll mod the standard kyser tonight for my regular acoustic.
Luckily, classical capos are $5 more than standard.
