FRIPP GUITAR TYPE ALGORITHM

I am using two H9 (2nd a core) and play different sizes of recorders transforming the sounds of the instruments.

I was wondering how to tweak one the algorithms to get the sound Fripp
uses for his single note in Peter Gabriel's "Mother of violence" (1978).
Sort of fuzzy sound that appears in 2'44'' and lasts only 5 secs. I
tried with the Octaver but always get and extra octave sound and the
result is not satisfactory. If anyone could help on that I will be very
grateful, thanks a lot!
