Description
Every guitarist who’s chased the sound of a screaming British stack eventually runs into the ghost of the Dallas Rangemaster. Tony Iommi, Brian May, Marc Bolan, and Judas Priest’s KK Downing and Glen Tipton all leaned on that circuit to push their tube amps into a cutting, harmonically rich snarl that became the blueprint for proto-metal tone. Catalinbread’s Naga Viper is built on that same foundation, but it doesn’t stop where the original did.
The vintage Rangemaster gave you one knob — Boost — and most players just ran it wide open, using it purely as an output volume trim on a fixed treble-boost voicing. The Naga Viper keeps that classic circuit at its core but adds two controls that turn it into a far more flexible tool on a modern board:
- RANGE — sweeps continuously from the original’s narrow treble-boost character all the way to a full-range boost, so you’re not locked into one fixed frequency
- HEAT — dials in the gain saturation level, letting you back off from the original’s always-maxed-out gain or push it further
Placed up front in your chain ahead of a cranked tube amp, it does what the Rangemaster always did best: thickens the mids, adds cutting harmonic edge, and shoves your amp into that juicy, rock-forward growl. But with Range and Heat in hand, you can chase everything from a glassy, articulate treble kick to a saturated, full-spectrum push — all from a single pedal built around a proven, legendary circuit.
