Flamma FV02 Vocal Doubling Effects Pedal — mint condition, used for only one practice session. This is a dedicated vocal effects stompbox built around a doubling effect (simulates a second vocal take layered with your voice for a thicker sound), plus built-in reverb and chorus effects to add depth and space to vocals live or in the studio. Compact stompbox format, easy footswitch operation, works well for singers and vocalists wanting quick, natural-sounding vocal thickening without a full rack processor. Runs on 9V power (used a power supply/pedalboard power). No power cord included.
