I was at a buddies place the other day doing some troubleshooting. He's got a couple modeling gizmos, a CLR and the Headrush. Trying the CLR and Headrush side by side was quite enlightening. The Headrush is AWESOME! Holy Crap. The Headrush is an AWESOME way to waste money! It's horrible. Just terrible. Ridiculously exaggerated low end and a shrill top end that even Roy Buchanan couldn't take. If this is what people are playing their modelers through I feel bad for everyone that has to hear it.
