Not really, because [comb~] also has two delay lines, one for input and another for output, in the same way! The thing is that it'll have the same delay time for both lines, whereas in teeth~ you can specify different times for each delay.

see my patch attached comparing them.

Well, not quite. You also need another delay line, as each has different
input (input and output signal). And writing code is more fun than
reading/understanding/adapting. I prefer the array aproach above the
pointer arithmetic that real programmers use :-).
