From OBNE:

Black Fountain emulates the sound of an oil can delay: warm, modulated, and a little gritty. Its perfect for chorusing, doubling, slapback, and long rhythmic delays alike. You choose the amount and rate of modulation, the tone and grit of the core voice, the two delay times and their feedback, and the mono/stereo voice of it all. For integration into many different rigs, Black Fountain has:

• Stereo in and out with analog dry through

• Trails or true bypass switching

• Presets

• Expression control over every knob

• MIDI control over everything in the pedal, including MIDI clock in and out for external syncing

Controls

• Rate and Depth to set the modulation speed and amount

• Tone to shape the warmth of the repeats

• Grit to set the amount of drive in the repeats

• Time L and Time R to set the left and right delay times, as well as choose between six subdivisions for each when holding the Tap footswitch

• Feedback to set the overall feedback amount

• Dry to set the volume of the dry signal

• Wet to set the volume of the delay

• Space to define the mono delay mode or stereo width, and add diffusion past noon

• Tap/Aux switch to tap in tempo, hold for infinite feedback, or optionally use as a preset switcher

• Soft-touch Bypass footswitch with relay switching for minimal switch noise
