The Radar Delay is a natural sounding digital/analog delay, with analog direct signal path.The Delay has about the same bandwidth as the classic tape echo units, and it can be used in front of an amplifi er or in amplifier effects loops. There are no noise reduction circuits, which keeps decay of echo as natural as possible. The direct signal path is short and made with analog amplifi ers with no fi ltering. There should be no distortion or tone coloration as long as input level is in range below maximum allowed. The echo signal has a tuned fi ltering to allow extreme settings without interference. The delay is specially designed to work well with distorted tone, as this is the most critical application,where delays often fail.You can use the pedal before or after distortion.As such, it will work exceptionally well on clean sounds where requirements are less stringent,especially in terms of echo bandwidth and repeat formation. The delay tone has been carefully tuned with lot of attention to the fi rst critical reflection and how the repeats decay. The Delay is kept small (69 mm x 111 mm x50 mm including jacks and knobs) containing just the basic delay features; Delay Time, Delay level and Repeat controls. It was designed to work as an ambience delay; like that of a vintage tape echo and the repeat formation was specifi cally designed to allow easy setting and less critical setting of delay time. With delay times higher than 120ms, the delay time is sometimes set on the beat or on a multiple of the beat. Deep Blue handles this by not giving full range repeats, but a tuned response that don't need to be on the beat to sound good.
