Absolutely not. If anyone has ever messed around with analog synths, plug in effects or even soft synths, you know that there is no "simple" way to achieve full adjustability. I mean, I used to use a Moog Little Phatty (now I use the sub phatty) and almost every knob on the LP was a multi-function knob.
It would be a different story if the extra adjustability made it so you land it bad tone zone too quickly. The SA pedals I've used almost always sound good no matter where you set them, unless you make it a point to try to get a bad sound.
The reason I really like the SA filters is that there is not a "baked in" sound. They can emulate a lot of other pedals but don't force you to conform to pre chosen parameter based off of the designer's personal preference. I personally really like being able to have control of almost every aspect of the filter.
