Audio examples

At the end of the 70s, there was one fx company leading the way when it came to innovations in digital sound technology. Many of the effects units they produced quickly became popular with top stars of the day.
The now legendary “BlueFace” Digital Delay in particular was favored by such musicians as David Gilmour and Frank Zappa who widely used the “BlueFace” digital delay in their touring racks and recording studios. Other famous BlueFace users include Joe Perry (Aerosmith), Roger Waters, Brian May, and Mike Rutherford to name but a few.

When first introduced in ’76 it was priced at $1000. Although expensive, it cost a lot less than the other digital delays available on the market at the time.
The addition of a stereo output on the 1u space rack-mounted unit allowed for a very deep stereo chorus effect.

Optional memory boards were available and could be inserted in slots on the unit to increase the delay time. These however were pretty expensive, costing almost as much as a complete unit

Digital Delay has a maximum bandwidth of 20KHz. As delays become longer this decreases down to 2.5KHz.
The longer the time between repetitions, the tighter the passing frequency band, being reduced through antialiasing filters (HPF and LPF).

A series of buttons on the unit are used to select the delay range, which ranges from fractions of milliseconds to 1280ms.

Different delay modes can be used to produce a range of different effects.:
- Flanger (1.25-2.5 ms),
- Chorus (5-20 ms),
- Doubler (20-80 ms),
- Echo (80 - 320 ms).

Turn2on DIGIDELAY Rack Extension is a modern take on the BlueFace delay. It retains the basic functionality and character of the original module with the addition of some new features which include clear sound and sync modes for Delay Time and Sweep Frequency.
Four optional memory boards have also been provided with the module to reduce delay range time.

DigiDelay can be used for “traditional slap echo”, discrete echoes, doubling flanging, pitch alteration (pitch-bending, vibrato), frequency modulation, and infinite repeat hold.
