The Poll question of "At What Point Is No Guitar Amp Worth The Price?" is completely subject to how much a person is willing to spend. For me - that's $1K. But the question really has nothing to do with "how good" the amp is. One simple example: Is a $5K amp really that much better than a VOX AC30? Would Brian May or the Edge have been more successful or had better tones with a $5K amp?
