Line6 DL4 and Echo Pro, Boomerang, Gibson Echoplex, and Electrix 
Repeater can do this, though perhaps not with the same relationship 
to the E-H's delay-with-feedback mode of looping.

Any variable-clock delay will do this. It was the standard in the 
early '80s. Lexicon delays all did it.

This is just a halving/doubling of the clock rate.

Eventides have lotsa modulation.

The main issue (other than the particulars of specific sound quality 
and control layout) seems to be the way variable clock (dynamic 
modulation and half/double speed) interacts with feedback, infinite 
hold (loop), and the forward/reverse toggle. Individual combinations 
of these effects can be got from other units, but the "whole 
enchilada" maybe not (unless you have a Kyma system or are working 
with MSP).

For instance, I can do a lot with an Eventide H3000 using mod 
factory: up to 32 seconds of delay with feedback, modulation, and 
infinite loop, but it won't do reverse. With a DSP4000 or Orville I 
can do forward/reverse, but it does this in "sampler" mode and won't 
function as a long delay within the same program.

So yeah, I guess the Electro-Harmonix is sui generis.
