I hear less clipping with Phase 100 although I use a passive jazz and I haven't really had any particular clipping problem with Phase 90. I'm still waiting for my Phat Phuk B to see how it will handle a hotter signal. It doesn't sound too subtle on the first setting (biggest wave/depth) IMO since it's not a dark sounding phaser like say Grand Orbiter which just went way too deep for my taste. Not too many good clips of Phase 100 on bass on the Internet besides Juan's short clip and one clip I found of a guy testing it against a digital multieffect (not sure which one). Aram Bedrosian did a clip but it sounds way too subtle (he set it on the most subtle setting). Honestly, I like both Phase 90 and 100, preffering the 100 tone but I for one found out I don't need a phaser with all the bells and whistles and tons of control. If I like the inherit tone, that's it for me. Phase 100 is exactly that IME.
