another way is to use the ring mod/MFX 18. set ctrl 1 and 2 hard left and then dial ctrl 3 as desired.

one suggestion I'd have for this is to make sure that you have the right type of waveform, etc sampled. an important part of the wobble bass is that a low pass filter modulate the sound. the problem with using a sine wave here is that it has no other frequences other than the fundamental...and thus doesnt really respond much to a lowpass filter. A better choice here is to use a sawtooth wave or a square wave (which can be mimicked by running a sine though distortion/overdrive). to get raw waveforms, you can probably download samples or download a free vst and sample the raw wave forms.

Didn't all this wobble come about by Madlib making the most of the sound you get with the SP's dodgy BPM adjust?
It's the sample stretching that it comes from.

that's exactly what i said on page 1 of this thread. so someone else gets it. thank you!
