Pete Townshend's windmill-strumming attack through a cranked Hiwatt is one of the most powerful rhythm guitar sounds in rock. On Won't Get Fooled Again, the SG's humbuckers hit the Hiwatt DR103 at full volume, producing a massive, ringing power chord tone with incredible clarity and sustain. The Hiwatt's enormous clean headroom means it stays articulate even when pushed hard, preventing the mush that a Marshall might produce at similar volumes.
