First, let’s clarify a few things.
- It would be good to know your audio interface and computer OS.
- Have you recorded a real guitar on an Audio track or a synth type guitar on an Instrument track?
- Can you hear the clean guitar when you play it back?
- If on an audio track, have you assigned the Amplitube (or Ampsinulator) VST effect to that track and picked a effect sound and activated the VST effect?
- If you recorded some midi on an Instrument track these VST effects won’t work (and really would not be available to choose). So did you assign a VST Instrument and choose the instrument sound and activated the VST Instrument?
