T-Rex BetaVibe Chorus/Leslie
T Rex · pedal
The T-Rex BetaVibe is a Uni-Vibe-style modulation pedal from T-Rex Effects in Silkeborg, Denmark, combining chorus, vibrato, and a Leslie-style rotary speaker mode in one enclosure. The chorus and vibrato modes reproduce the swirling, watery, Doppler-effect character of a classic Uni-Vibe, while the rotary mode adds the spinning, speed-ramping character of a rotating Leslie cabinet for a different, more mechanical kind of swirl. It suits Hendrix-influenced, classic-rock, and psychedelic players wanting genuine Uni-Vibe swirl and vintage rotary-speaker modulation from a single pedal rather than needing separate units for each effect.
