yah, i did verify the vero layout...it works, but of the 20 chips i bought from different suppliers, almost all of 'em were wonky in this circuit..i'd say it's the chips, not the circuit.
i've had everything everyone has described, from lock up to insane distortion to bizzarre noise to even a low-pitched motorboating. switch chips, and it's a different problem.
switch the damn chips to other projects, and they all exhibit issues, too...so it's definitely the chips.
but when ya DO get a good one...it does sound nice.
i could never really get the lush pot to do much, unfortunately, but i think it's more because the damn chip locks up so easily.
i undid the mods i had done to it before, but did make one change...i took out r1, 1k and replaced it with a 10k trimmer, so i could play with the delay time a little..1k sometimes seemed just a little too little...and this way, it can do a nice double, with the trimmer cranked...
i like it right about 3.43 k the best, fwiw
