Can I only recreate amp sounds with a guitar VST?
This means that they'll work in many different DAWs and across Mac and PC – whereas AAXs only work with Pro Tools and AUs will only work with GarageBand or Logic Pro X. The best guitar VSTs are slightly different to regular plugins, as they work across multiple formats. Which format you choose will be largely influenced by which operating or recording system you are using, due to the fact that plugins that are designed to be used inside a DAW will be based on a few different formats: Steinberg's 'Virtual Studio Technology' (VST), Apple's proprietary 'Audio Unit' (AU) format or Avid's 'Avid Audio eXtension' (AAX).
