Dsm Humboldt Electronics · pedal

The DSM and Humboldt Electronics Sub-Atomic X-Over CMOS Bass Preamp is a dedicated bass crossover preamp pedal using CMOS circuitry to split the bass signal into high and low frequency bands, processing them independently for separate drive and tone shaping. The crossover design allows overdrive to be applied to the high-frequency content while the low-frequency fundamental remains clean, preserving bass definition and punch while adding harmonic distortion character to the upper frequencies. Made by DSM and Humboldt Electronics for professional bass applications.
