i would go with the TC electronics Vintage delay. Its such a sweet sounding, natural delay, with a filter switch to make the true tape echo sound as it deteriorates. They are expensive though, but tap temp, triplet switch, effect level, knob for delay rate (as well as tap) and output. The lights are hella bright, strobe light too. Excellent pedla, the -rex delay is the same but a little cheaper, i just liked the TC's lights.
Hope it helped
