Boss NS-2 Noise Suppressor
Effects pedal · Japan
The Boss NS-2 Noise Suppressor is a compact utility pedal that removes unwanted hum and hiss from guitar and bass rigs while preserving the instrument's natural dynamics. Its sensitive analog circuitry avoids choppy gating artifacts, and a built-in send/return loop lets players place high-gain pedals inside the loop for cleaner noise control.

The Boss SD-1 Super Overdrive is a compact stompbox released in 1981. It uses an asymmetrical clipping circuit to produce warm, tube-like overdrive with Drive, Tone, and Level controls, and has remained a long-running core gain and boost pedal across rock, blues, country, and metal.

Effects pedal · Japan
The Boss OC-5 Octave is a compact octave pedal that adds notes one and two octaves below the input plus a new octave-up tone. A Poly mode tracks full chords while a Vintage mode recreates the monophonic OC-2, and a Guitar/Bass switch and Range control optimize tracking for either instrument.
