A table-top effects unit from 1987 with great 80s digital effects.

Despite the limited controls, every effect can be customized, and changes can be saved to memory to be recalled later. Particularly good for delays and digital distortion.

Features
Reverb: 80s digital technology reproduces the acoustic reflections of various environments. Other reverb effects include early reflection, gate reverb, and revers gate.
Delay and echo: independently programmable right and left channel delay and echo effects with adjustable feedback allow creation of a broad spectrum of delay effects.
Distortion: an extremely powerful and flexible distortion effect, by itself or with other reverb, delay, and modulation effects – making the REX50 essentially two effects units in one.
Modulation: Stereo Flange, Chorus, Stereo Phasing, and Symphonic effects.
Gate: a high-performance noise gate with a fully programmable ADR envelope. Extensive triggering functions enable creation of an incredible range of unique sounds.
Compressor: compression can be used to sustain sounds (such as a guitar), or smooth out the volume extremes of particularly dynamic sounds (such as vocals).
