Mixed around 1999 on a old MDF4.
At this time, I was using a GT-5.
Feedbacker effect is used at start to simulate a sampura.
I "sitarished" my clean sound with a delay with around 97% of feedback and a short delay time (2 to 8ms if I remember well).
A Wah-rocker by Guyatone was used post delay to make the sound "miawing"
.
I'm sure that is not really closer to a real sitar, I know that because I've one from New Delhi since 4 years ago, so, now, I can compare
.
After composing that sample, I replaced my GT-5 by a GT-Pro that contain some kind of useful sitarish effects. I wasn't really convinced by Sitarsim effect but combined to Defretter, delay (as told before) and a few auto-wah, and also, played from a fretless guitar, that was really interesting.

I don't have any clip of its tone, but it sounds better than the one I linked on top of this post.
Also, using the delay like that is making a few "auto-oscillation" problems. In fact, combination of a short delay time and high amount of feedback is creating a frequency resonance that varying with the delay-time setting. So, it's necessary to tweak those two parameters in phase with the tonality of the song you play.
