Electro-Harmonix SYNTH9 – effects pedal

The Synth9 transforms guitar or bass into a range of vintage synthesizer sounds that capture the essence of classic analog and string machines. Unlike MIDI solutions, no special pickups are needed, and the Synth9 responds instantly to your playing style, making the experience natural and intuitive. The pedal offers nine synth engines, ranging from OB-like brass pads and Solina strings to powerful mini-lead sounds and deep Moog bass. Each preset has adjustable Attack, Dry/Synth mix, and two specific parameters that shape filters, modulation, or envelope behavior. The tracking is exceptionally accurate, both for single notes and chords, ensuring that vibrato and dynamics retain their expressiveness. The Synth9 shines in electronic music, cinematic soundscapes, indie ambient, and retro arrangements, giving guitarists access to rich textures normally reserved for keyboards. Thanks to its simple controls and studio-quality sound shaping, the Synth9 bridges the gap between string instruments and vintage synth aesthetics.
