The LP2+delay board has a very characteristic sound when the delay is set to a high feedback ratio with the feedback EQ set to a high-enough value not to attenuate the mid-range. This is due to a “bump” at 3kHz in the response of the filters surrounding the PT2399. The resulting sound was oddly familiar to me and I have finally found where I had heard an occurrence of this kind of build-up right at 3kHz in the past.
This is on the track “Imagine” by Voodoo Warriors of Love, on the em:t5595 compilation. Sample attached.
