Thank you very much for your answer !
I have seen price of the moogerfooger and it's a little bit pricey for
me... I thing that the rs400 is a good solution.
However, I read some articles on the Net and there is something not very
clear for me : is a phaser the same as a comb filter ? My opinion is that
a phaser is a comb filter with the delay controled by a lfo. Am I right ?
