I've got myself an Old Blood Noise Endeavors BL-44 reverse delay and I am pretty obsessed with it, I can't stop playing it, it's very inspiring. Most of the time I keep the clock fully on the left and speed at 1 octave up or unison. It makes you play super slowly, it's a bit unpredictable, but adds a really beautiful layer, forcing you to take your time, note after note ❤️ Overall the BL lineup is pretty dope.
