Mad Professor Deep Blue Delay

BJF design ambient delay pedalThis 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.Controls:LEVEL: Sets the level of delayed signal mixed with straight guitar tone, fully CCW there is only straight (un-effected) guitar signal heard and fully CW gives the loudest delay.DELAY: Controls the delay time from 25ms (fully CCW) to 450ms (fully CW)REPEAT: Controls the repeats of the delay signal, fully CCW gives one repeat and at fully CW you get infinite feedback.BIAS: Controls the filter resonance frequency. When Sensitivity is turned fully off the Bias can be used as a sweepable filter.RESONANCE: Controls the sharpness or Q-factor of the filter.DECAY: Controls how fast the filter frequency falls back to resting point (that is set with the Bias control). This can be set fast (CW) so you get the wah effect on every note or slow for a more traditional auto wah sound.PLAYING: Please take time to get used to the controls and as this is a voltage control filter it will react to your playing touch.The envelope control circuit is carefully designed to follow the dynamics of guitar/bass and it might take some time to master the Auto Wah playing technics.Try also adjusting guitar volume between 8 and 10 to further expand use.Electrical specificationsSupply voltage: 9VDCCurrent consumption at 9VDC: 15mAInput inpedance: 500KOutput impedance: 1KMax input -20dBVComplete bypass (true bypass)
