It would be an understatement to state that I found OBNE's Procession reverb immensely disappointing. It was noisy, limited in its range, and pretty expensive for what you get. So it is with wiggling rivulets of joy that the verdict on the Black Fountain is so so different.
Which technically is different to saying the Procession is shit.
The Black Fountain is a murky delay that isn't as fun as a tape echo and it has some weird modulation that isn't particularly good on it. One of the modes is pretty much a slapback delay with a basic reverb on it. With the mix knob at 50%, the delay sound is really quite weak compared to the dry sound.
It's not horrific but there are many better echo/delays out there and the limitations of this oil can delay replica pedal are really shown by comparing it to the oil can settings in the Echoboy plugin.
Great if you like murky delays that sounds a bit flat.
