The Vesta Fire RVD901 is according to it’s advertising material, a fully adjustable digital reverb of outstanding quality. Eight preset reverb effects are available including gated and reverse reverb effects. But the RVD901 does not limit you to just eight presets, because each one is fully adjustable using controls for pre-delay (a must for obtaining clear well defined reverb) decay, hi and low cut filters and effects mix.
The Vesta Fire RVD901 is a high-performance digital reverb incorporating 8 basic reverb algorithms (called “modes”) and 5 controls, allowing for limitless variations, well, almost.
With the Vesta Fire RVD901 both Mono in/Stereo out, and Stereo in/Stereo out operations are possible, enabling you to give a stereo effect to monaural output instruments and to apply reverb to stereo sources without losing the original stereo sound.
Reverb time can be controlled through Pre Delay and Decay adjustment. High Frequency Dump and Filter functions enable you to change the sound characteristics. Moreover, special effects can be attained using the Hold feature. On it’s release back in 1986, the Vesta Fire RVD901 sold for £265 in the UK, making it one of the most affordable digital reverbs on the market at the time.
