You could always try using kits for some dubby wobbles... I have used the pacman sound in (insert kit name here) and in the table I think I just set the pitch much lower. If you wanted, you could make your own kits via .wav files for the desired sound. I do not think, though, that kits have as much power as the the normal waveform, so just keep experimenting... I mean, like 57.63% of the fun of LSDj is looking for interesting instrument combinations.
Almost forgot... if you make some saw wave wubs, then try to enhance their grandiosity with some subtle 12.5% pulse waves in the background...
