That is a perfectly rational outlook.. it would save money, be way more comfortable to play, possibly even sound better, and totally suck.
I may not be really good at anything in this life, but one thing I do uphold is to try my hardest at everything I do. If I just went up there with a regular guitar, I would bum so many people out! The band, the audience, the venue, the promoters, the sponsors, the memory of my dead best friend and bandmate, and myself. There is only one thing on this planet that I'm dead-serious about, and that's having a good time and entertaining people to the best of my ability.
Besides, those silly guitars did a lot for me and my old band. Playing without them would be like losing another member of the band, and I'm not emotionally equipped for that right now.... Oh, and do I need mention that I really really like customizing guitars? Building a new one is like forging your own sword before going into battle...
Simple question, excellent answer.
The reason I asked is that you said it was going to be heavy, uncomfortable, etc.
