well... They're pretty much like tuning guitars or whatever, you do turn the pegs. And as for stringing them, it's pretty much like stringing a guitar. But, if you don't know how, I think that ya should go to Bruce Millers or the shop just at the Holburn Junction to get it done by a pro -- That's from my friend who plays Cello by the way, lol.
