Classic rock - YES. 90’s garage rock - YES. Turn up the Super Fuzz side with a medium gain setting, dial in the bias for maximum sustain and let the power chords ring out. Turn up the gain and twist the bias to squeeze that signal down to a compressed electronic wave for single string leads and score a spy movie. Flip the mids switch down and enter the realm of the Wizard of Doom.
Something a little warmer, maybe? How about the EC fuzz? A streamlined Eau Claire Thunder can be dialed back to overdrive range or cranked up to a raging wall of thunder. Wind it into an aggressive sustained lead machine. Blast the Tone control for the huge, blown out, "Am I going to break something?" juggernaut you've come to expect from the Thunder.
