Electro-Harmonix BASS9 Bass Machine

The Electro-Harmonix BASS9 Bass Machine, introduced in 2019, is a polyphonic pedal designed to transform a guitar signal into nine distinct bass emulations without requiring special pickups or MIDI modifications. Part of EHX's acclaimed "9 Series" pedals, the BASS9 uses advanced algorithms to deliver realistic bass tones spanning decades of musical styles. With modes ranging from classic electric basses like the Fender Precision Bass to synthesizer-inspired sounds like the Roland TB-303 and Taurus Synth, the pedal offers exceptional versatility. It features controls for Dry and Effect volume, as well as two parameter knobs (CTRL 1 and CTRL 2) for fine-tuning each mode. Its seamless tracking and dynamic response make it suitable for studio recording, live performance, and experimentation.
