the Dynacord VRS-23 analog delay

(click images to enlarge)

The VRS-23 was a quite successful BBD delay in the 80’s and some thousands of units were sold during that time. It’s a mono-in / stereo-out device and capable of delay times up to around 400ms. Providing also very short timings and a modulation option makes it capable of creating chorus and flanger type of effects as well. There were different revisions available and shown here is a later one with the white faceplate. [Read more…]

the Ibanez AD202 analog delay

The so-called bucked-brigade device (BBD) delay line generator is a somehow quirky and really unique technical design. Such  devices are built upon analog components entirely, but being discrete in time they are halfway digital. Their analog input voltage samples are stored and moved through a line of capacitors one step after another and hence the name comes from analogy with the term bucket brigade: a line of people passing buckets full of water.

the classic chorus echo device

Beside the usual suspects when it comes down to the individual classic echo or chorus devices there were also some combined devices build around true tape delays or bucket brigade delays (BBD). Looking from todays production standards they might be easily overseen and this is no wonder since their golden decade refers back to the 1970s right before the digital delay devices emerged during the 1980s.

Some example devices are:

  • Rockman Stereo Chorus/Delay
  • Roland DC-30 Analog Chorus-Echo
  • Roland SRE-555 Chorus-Echo
  • Roland RE-501 Chorus-Echo
  • Ibanez AD202 Analog Delay
  • Yamaha E1010 Analog Delay
  • Dynacord VRS23

Beside the delay unit itself they typically contain a Chorus/Flanger/Ensemble sort of effect as a switchable option or offer a direct and straight delay line modulation instead. Comparing them to todays feature blown digital delay units they might appear feature wise rather poor and limited but in some cases they were groundbreaking to their time providing a sound palette ranging from smoothest chorus goodness up to weird and feedback distorted audio fx oddness. This and their unique sound quality is probably the charm which still today attracts producers and audio engineers to use this sort of stuff.

Does the list miss some crucial device and are you still using such device and why?
