I'm going to the studio later this week and am planning on recording 2 tracks, miked amp and DI. I'd like to know wether I should use a DI box, my amp's DI pre, or my amps DI post (pre meaning before the pre-amp and post meaning after)? I might only use a DI too, depends on time, unless they record both at once. I know this is rather redundent, but I haven't seen any post DI vs. pre DI threads. I have a Series 3 carvin redeye combo (R600 Head) It has a DI level knob too.
