How to Hook Up My Marshall Amplifier Recording Jack

When you plug a guitar into a Marshall amp, it is first processed by a pre-amp, which takes the raw signal coming from your guitar and amplifies it to line level. From there, the signal passes through a power amp, and then out through cabinet speakers, which is where all the signature distortion that gives an electric guitar its sound comes from. Some Marshall amps have power amp and cabinet emulators if you are looking for the complete Marshall sound. You can also record a clean signal from the pre-amp and add distortion later when you're mixing.

Instructions

    • 1

      Plug one end of the TRS cable into the guitar, and plug the other end into the "Input" jack on the amp.

    • 2

      Plug one end of another TRS cable into the "Line Out" jack on the amp, and plug the other end into the "Input" jack on the audio interface. This will route the guitar signal through the power amp and loudspeaker emulators.

    • 3

      Unplug the TRS cable from the "Line Out" jack, and plug it into the "Pre-amp Out" jack, if you wish to bypass the power amp and loudspeaker emulators. This will give your guitar a clean, undistorted sound.

    • 4

      Turn the "Pre-amp Volume" knob to adjust the level coming out of the "Pre-amp Out" jack, or turn the "Line Level" knob to adjust the level coming out of "Line Out."
