Heard about this product on Phillip McKnight's youtube channel. Replacing the first preamp tube in the HRD with the 12AT7 sorts the issue the amp has with jumping to life at volume setting 2, then getting exponentially louder from there. The volume swell is more gradual after the switch, making it possible to play at practice volume.
