In the long history of BOSS compacts, the SP-1 stands out as one of the most unique pedals. Derived from an effect built into some early Roland guitar and bass amps, the SP-1 is basically a single-band parametric equalizer with a fixed level boost. The Spectrum knob allows you to sweep the center frequency from 500 Hz to 5 kHz, while the Balance knob adjusts the mix of the direct and effect sounds while keeping the overall level consistent. When used with guitar, the SP-1 produces a sound similar to a wah pedal set at a fixed position, but with a more focused boost at the center frequency. However, the SP-1 was most often used by bassists, who found it to be a great tool for cutting through the mix on stage. In either application, the Balance knob is very useful for filling out the sound with a bit of direct tone as needed. The SP-1 was produced in limited numbers until 1981. It’s probably the hardest vintage BOSS pedal to find on the used market, and commands the highest prices as a result. For the reissue, each individual preset resistor has been meticulously tuned by hand, ensuring fully accurate reproduction of the original SP-1 sound.
