NAGA VIPER MKII

Brian May, Eric Clapton, Tony Iommi, and others pioneered the use of the Treble Booster, more specifically the Dallas Rangemaster. One thing that made this circuit such an anomaly in effects canon was its lack of foot control; the Rangemaster was an amp-top device with a teeny-tiny toggle switch that was an absolute pain to disengage mid-riff. Of course, back in 1966 when it was invented, "pedals" as we know them today didn't exist yet. For those players, their rig consisted of amp, Rangemaster and guitar.
