Full Bucket Music: Bucket Brigade Delay

A free plugin that emulates an analogue delay.


11 December 2023

German programmer and software engineer Björn Arlt began building VST plugins under the name Full Bucket Effects in 2010. Being a musician, and a synth enthusiast from a young age, he was drawn to analysing and building software synths. He now offers both synth emulations and effects as freeware through his website.

The Full Bucket Brigade Delay is an offspring of the tiny delay within my Nabla synthesizer, and simulates the functionality and sound of classic analogue delays. Since the ‘buckets’ of a BBD are not perfect analogue memory elements, the signal quality will degrade with the length of the BBD and the clock rate. Typically, the frequency range of the delayed signal is smaller than that of the original signal, and the delayed signal may be slightly distorted.

In the Delay section you can select the delay time range (1‒8ms, 4‒31ms, 16‒125ms, 31‒500ms, 250–2000ms), set the delay time itself, and adjust the feedback level. Note that changing the delay time will change the frequency of whatever signal is already ‘in’ the delay line.

  • Authentic simulation of a Bucket Brigade Device (BBD) delay line
  • No crackling or dropouts when changing the delay time
  • LFO modulation for Flanger, Chorus, or other modulation effects
  • Sync-to-Host option
  • Freeze mode
  • Quality control to send your hi-fi signals to hell
  • Resizable user interface (not N version!)
  • Plug-in supports Windows and macOS (32 bit and 64 bit)

The Full Bucket Brigade Delay is available for Microsoft Windows (VST2/VST3) and Apple macOS (VST2/VST3/AU). It is written in native C++ code for high performance and extremely low CPU consumption.
