Deep Blue Delay HW

BJF design ambient delay pedal

This pedals is now offered as lower priced pcb-model or hand wired pedal.Both share the same specs and tone.

Deep Blue Delay (DBD) is a natural sounding digital/analog delay, with analog direct signal path. The DBD has about the same bandwidth as the classic tape echo units, and it can be used in front of an amplifier 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 amplifiers with no filtering.

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 filtering 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.
