I've owned a lot of delay pedals - Timeline, El Cap, Boss DD3 and DD5, Nova, DL4, Diamond Memory Lane Jr, EHX DMM XO, Panther Cub, and Mad Professor DBD. Most of them sound like there's a mathematical formula to the volume at which the repeats degrade. For example, if I strike a note on a Strymon Timeline dBucket setting, and I can hear 10 repeats, the volume of each repeats seems to decline by 10%. Again, like there's a mathematical formula. But the last 3 pedals I mentioned - DMM XO, Panther Cub, and DBD do not seem to sound this way. Their repeats are more organic. On the DMM XO and Cub, the first 2-3 repeats stand out, but then there's a more dramatic drop in volume for there rest of the repeats. I like this because I can use delay when playing rhythm, and it does not overtake my signal. The DBD is almost opposite. The first few repeats sit lower in the mix, but almost get heavier later on, creating this nice ambient wash. So are there other delay pedals that I did not mention that have a similar, organic quality to the degradation of their repeats?
