The Boss RDD-20 delay – Part of the classic Boss Micro-rack series which graced a huge amount of home studio’s back in the 1980’s.
The RDD-20 employs a 12-bit PCM system plus analog logarithm compression for high quality compatible with a 16-bit system. Continously variable delay time between 0.75 to 400ms with flat frequency response up to 15kHz. Also equipped with Delay Tone control.
The RDD-20 Digital Delay is a half-width rack unit from the 1980s Boss Micro Rack range. It uses 12-Bit digital circuitry to get that proper 80s sound. 12-Bit circuits tend to sound more analogue and less hifi than 16-Bit and they have a characteristic “Old School” sound. The RDD-20 will create delay effects from a super-short delay via slapback through to long quarter-note delays & repeats
The RDD-20 has a dedicated modulation section with variable depth & rate controls so short chorus & phaser effects are easily done.
When you look harder at the RDD-20 it becomes clear that a lot of thought went into the design of the Micro Rack series. The power supply has a loop-through connector so units can be daisy-chained. There’s a footswitch socket for effect bypass. Inputs & outputs are on phonos as well as mono jacks and there’s a rear-panel switch to shift the nominal operating level between -10 and -20 dBm. Maximum delay time is 400 mS
Front panel controls are simple: Delay time is set in steps and fine-tuned via a delay time pot. Modulation Rate and Depth control Modulation and the dedicated Feedback control sets the amount of delay fed back to the input. At higher settings, with short delays you’ll hear typical resonant flanging effects and, with longer delays, slow, dub-style effects.The Delay output section has a simple lo / hi EQ control and an Effect Level control to set the balance of direct & effect. There’s an effect bypass switch and a power switch
Keys to the depth of the chorus effect are pre-delay and the modulation section. By adjusting these it’s possible to create very subtle effects with movement but very little pitch modulation, or you can wind up the depth to get a traditional chorus with lots of detuning. Unlike simple stomp boxes, there’s lots of opportunity to shape the effect through experimentation
