So... what's inside the Suhr Reactive Load box? It's the impulse response era, so that's just what I do. Yet, nothing can beat a REAL tube amp, no axe, no fx, no nothing. It's the volume sweet spot along with the negative feedback and the presence control into a reactive load, that make the amp sound and respond to ones playing just right, and don't tell me a modeler can do that, I've tried them all. Besides, I can smell the Tolex cooking from the tube heat, no darn ass-fx can do that.
