    Hi everyone, I have a marshall combo and at the back is a switch to select 0db D.I. or 20db D.I. does anyone know whether this means I dont need a separate D.I. box and if so which of the 2 settings I should use for recording. Thanks muchly. Steve.

    It means you don't need a separate DI box if that one doesn't suck. Some DI's built into an amp are great, some not so much. Also for gigging many people carry a separate DI box as insurance in case their amp craps out.

    Of the two settings it will depend on what type of recording device you're feeding. The dB levels indicate how "loud" the signal is. What the amp calls 0dB is probably what most DI's would call "-20dBu" or "mic level", for a microphone input; and 20dB is probably what is usually labeled "+4dBu" or "line level", for a line input with no preamp.
