So i want to prepare for shows and i have experience with the spider iv half stack. Does the pod hd500 sound better than the spider in terms of sound speceifically for a live show? Im not talking leaps and bounds im just talking is it worth buying the pod over the spider when the spider is ready to go. Also say i went the pod route, are most people using the stage source option or using a cab with power amp?
