How To Reamp via GT-1000/Logic Pro

Background

GT-1000 provides three USB audio outputs: “MAIN”, “SUB“ and “DRY.”

  • Channel 1/2: Main out (1/4-inch): outputs the effect sound from MAIN OUT; the return from the computer is mixed with the guitar’s performance at the final stage of MAIN OUT.
  • Channel 3/4: Dry sound with no effects: always outputs the dry sound regardless of the GT-1000 unit’s settings; the return from the computer is always returned to the beginning of the effect chain.
  • Channel 5/6: Sub out (XLR): outputs the effect sound from SUB OUT; the return from the computer is mixed with the guitar’s performance at the final stage of SUB OUT.

Since the GT-1000 is outputting to the computer from each of MAIN, SUB, and DRY, you can provide three tracks for guitar and simultaneously record the dry sound, the effect sound from MAIN OUT, and the effect sound from SUB OUT.

If you are not satisfied with the effect sound from MAIN OUT or SUB OUT, you can play back the dry sound that was simultaneously recorded from DRY, and pass it through the effect chain of the GT-1000 to remake the sound. This is called "reamping".

Reamp Procedure

  1. Connect GT-1000 USB to Mac
  2. In Logic Pro, add 3 tracks:
    i. MAIN: GT-1000 inputs 1,2 -> GT-1000 outputs 1,2
    ii. DRY: GT-1000 inputs 3,4 -> GT-1000 outputs 3-4
    iii. SUB: GT-1000 inputs 5,6 -> GT-1000 outputs 5,6
  3. When recording the first time, record to all three tracks.
  4. Change the GT-1000 settings for a different sound
  5. In Logic Pro, pick the main or sub tack (or both) that you want to reamp.
  6. Record. This takes the DRY track and runs it thru GT-1000 (with the updated sound settings) the output of which gets pushed to the track(s) you are recording over.

If you want to listen while reamping, the easiest place is to listen to the headphone out from the GT-1000. By default, this is the main out, but you can change it.

There are lots of other optins, but make sure you are listening to the out you think you are listening to. I've found it to be confusing sometimes.
