Too abrupt a change IMO in most any wahs...I'm always wishing for some more travel and little less drastic change with small movements.
BTW that's why I always keep the wah first in the chain...if you have the wah after the drives, the wah screams a bit more but then the change is WAY pronounced, because the drive also changes drastically with wah movement...you can get a very pronounced wah quak that way but I like it a little less pronounced.
Best wah I have owned in terms of nice non-abrupt sound changes and nice travel was a Morley, but then it didn't much scream and wail either even when used with a heavy foot.
