Beta Aivin is a manufacturer of guitar and bass amplifiers, effects pedals, and accessories. The brand produces a broad lineup of stompbox effects — including overdrive (OD-100, OD-200), distortion (DS-100), heavy metal distortion (HM-100, HM-200), digital delay (DD-100, DD-2, DD-200), chorus (CH-100, CH-200, CE-100), flanger (FL-100), equalizer (EQ-100), octave (OC-100), and acoustic simulator (AC-100) pedals — as well as bass-specific effects like the BCH-1 Bass Chorus, BEQ-1 Bass Equalizer, and BOD-1 Bass Overdrive. The company also offers the ME-100 multi-effects unit, pedalboards such as the U-600S, and a range of combo amplifiers for guitar (GA series), bass (B110, BP-20, BP-35), and keyboards.

Beta Aivin pedals are housed in rugged metal enclosures, run on 9V batteries or optional DC adapters, and follow a naming and control layout reminiscent of Boss pedals. The brand occupies a budget-friendly segment of the market, offering functional alternatives to more established pedal and amp manufacturers at lower price points. Their products are distributed through music retailers across Europe, Southeast Asia, Australia, India, and Latin America.
