Both totally worth it if you can find the tape sealed don't open it uvcores. The comic is short but one of the best representations of bucketheadland you'll get besides The ballad of the Buckethead video and the film mirrormask. I would recommend them for sure and if your patient you might find a comic signed by big B himself. good luck and have fun.......oh yah and watch out for the revenge wedge..
