Well, yeah here's something you can do to speed up the process of calluses: you can simply rub your fingers across the strings furiously for a few minutes... naturally, it's not as fun as playing, but it is much less stressful on your fingers and it's very much faster. sort of like grinding exp in a computer game haha

definitely tt'aint like wrestling.. more rather it's like singing. once you hurt your vocal chords... :P can't sing!
