New high-end studio reverbs tend to sell for over $1000, and $10 Pioneer models produce a lot of noise. Orban's mid-80s rack-mount unit presents a reasonable compromise. With 2 channels selling for about $300 (used, obviously), it has relatively low noise, balanced outputs, and a characteristic spring reverb sound. It can control two bands of equalization for the returned signal. For a reasonable price, the Orban provides effective and functional reverb, with Orban's characteristic metallic blue faceplate.
