The Nobels ODR-1 is not another green overdrive clone. In fact, it sounds nothing like the ubiquitous green stompbox. A cult classic among Nashville session players, the ODR-1 is a natural-sounding dirt box that fits sonically somewhere between the mythical transparent overdrive and the aforementioned mid-forward green pedal. This pedal boasts a 3-knob control set with Drive, Spectrum, and Level knobs. Drive and Level are self-explanatory; however, the Spectrum knob offers something different. Rather than operating as a typical tone control, Spectrum enables you to simultaneously dial in your bass and treble without affecting your mids. The result is extremely transparent, and it flatters any amp you plug the pedal into. You also get a bass-cut switch, a remote input jack, 18-volt power compatibility, and glow-in-the-dark knobs. With its ability to tackle light harmonic coloration, blues-like grit, and hard-rock crunch with equal aplomb, the Nobels ODR-1 Natural Overdrive is the secret to the coveted Nashville session sound.
