The MXR 01A also known as the Model 191, was manufactured by ART (applied Research & Technology) and was a very expensive reverb at the time, selling for more than a Lexicon PCM 60.
The Bel BD-80 processor is a high quality digital delay with an expandable memory with loop edit facility, synchronised record and playback (sampling), keyboard control (1 V per octave), echo and flanging.
The Bel BD-80 must be one of the most popular delay/samplers ever produced, it is found in all types of studios from the most modest home set-up to the more prestigious 46 track facility. The BD80 had two features that enable its use across the wide range of recording studios; an excellent audio quality combined with a modest price.
The BD-80 now has a successor which also combines these two qualities, welcome to the Bel BD80S “Stereo” Delay/Sampler. The BD80S enables stereo delay effects and “TRUE STEREO SAMPLING” – over 6 seconds at 20HZ – 20KHZ band with ( 13 seconds in mono).
When I want delay, flange, even a short sample this is the machine I go for. It’s clean, a touch sweet sounding and has no nasty traits.
