This used Catalinbread Naga Viper Treble Boost Pedal is in Very Good condition with normal signs of handling and use.

FROM CATALINBREAD:

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.

None of the legendary Rangemaster players had many controls to work with, so we’ve reconfigured the circuit with that ethos in mind. The knobs on the Naga Viper aren’t there for constant twiddling, just set it up how it works for you once, then leave it alone and play that thang!
