Delays that are not supposed to be stereo

None of these delays have ping pong settings but what they absolutely have is a sound of their own. I captured tem in mono with proper feedback, so they can show their true colors in the tail of the delay. Then I duplicated the track and offset the tempo so they sound ping pongy. I plan on doing circular versions on these as well. Load these in a convolution reverb plugin, after your cab or in an aux track, 100% wet. The 2290 sounds very pristine, percussive and atmospheric. The PCM42 has a high cut around 6k, maybe a bit higher. Sounds warmer but still has the definition of a digital delay. The dd3 sounds the most "distorted" but tends to blen very well with distorted guitar sounds. If you have any ideas of delays that shouldn't be stereo but f-*- it let's do it, let me know!
