🎸About: Doctor McFarland is not a real doctor though he does heal people with “sweet rock n roll” and gets surgical with audio.

The Headrush line of products are amp and fx modelers that allow you to set up multiple rigs and switch between them at the push of a button. You can also set up scenes for greater flexibility.
