I would love to see this; an amp head maybe 500 watts or more but the amp itself is not what my idea relates to it's the di. A di ob the amp that has a defeatable speaker Sim that includes 10, 12 and 15 speaker emulation. A few mic emulations. On axis off axis switch and an ambience knob. I have no technical knowledge but it would be great if it could include a battery so that it could remain operational even if the amp died. So do you think this could work/ be practical and would you add anything?
