Miniaturized DRIVE Breaker DB-1, modifyied focusing on distortion degree, EQ range and noise reduse. DB-1S is adjusted the density of the distortion component while retaining the comfort of the DB-1 so as to correspond to various styles. Especially noise becomes a problem in DAW and pedal effector, but realized "no buried" distortion which made it feel vivid even if it distorted more. It is the birth of a new DRIVE Breaker that supports home DAW and Jazz Chorus which is standard in the live house and the studio. ** The original DB-1 is recommended for intense rhythm guitar and heavy bass sound!
