My favorite effect is a toss up between Analog Tape Echo and Spring Reverb. The new Nomad Factory Echoes plug-in emulates some classic Tape Echo boxes. I have a Boss DM100 (not actual Tape) and often use Fabfilter’s Timeless both which I highly recommend. I love the detuning effects you can achieve as you mess with the delay time.
“ECHOES faithfully models the greatest delay effects of all time, PLX-1 based on* Echoplex® 1, PLX-3 based on Echoplex 3, OILCAN based on Tel-Ray® Oilcan Delay, EHX-DM based on Electro Harmonix® Deluxe Memory Man, and ADM-2 based on Boss® DM-2 Analog Delay.” – nomadfactory.com
