But, to be fair, it isn't the easiest job for a soundperson to deal with three or four completely different band setups, rigs, and performance styles in an evening, and the gremlins of over-amped stage sound and signal bleed are always in the wings, eagerly waiting to trash all efforts at delivering a balanced mix to the audience.

Well, here's a secret weapon for you. The JDX ($199 street) is an active, amp direct box that is plugged in between your amp head and speaker cabinet. (It can't be used as a standard DI for bass, keyboards, or other direct-injection applications.) The JDX's transformer then acts as a reactive load that simulates how an amp and speaker respond to a guitarist's dynamics, and a speaker-emulated output from the device (mic-level XLR) can be routed to a mixing board.
