Pedal Kit - Mod® Electronics, Seismic / Shift, JFET Boost
The Seismic / Shift is a JFET boost based on one of the earliest effects to ever be used on stage. This pedal adds subtle color to a guitar's sound while maintaining the natural tone of the guitar. It packs a serious punch that can cut through any mix when soloing or whenever some extra “umph” is required. The Seismic Shift pairs nicely with amps and other pedals. Place it ahead of tubes, preamps, overdrives, distortions, and fuzz pedals to shift your gear onto a new level.
The Seismic / Shift pedal kit is the introduction to the Nexus Series from Mod® Electronics. This series features a PCB base rather than the Mod® Electronics’ traditional point-to-point wiring kits to offer builders an even wider variety of effects to build. The Seismic Shift kit is designed for all skill sets and is the perfect first build for those unfamiliar with PCB construction.
The pedal operates on both 9VDC and 18VDC. A center negative power supply is required for use (not included w/ kit). There is no battery connection. When using 9VDC the pedal draws 8mA. When using 18VDC the pedal draws 16mA. The enclosure size is a standard 1590B (4.4" x 2.4" x 1.2").
