Adjust the level of the signal going into the pedal, and observe how that changes the response and tone of the effect. |

The FX25 and 25b are basically the same tonally, but the original 2 knobber does not have the volume drop when engaged. All versions of the FX25 have the potential to gut the lowend if not played correctly, and they require more user input control than any other filter I've tried. It's not the most versatile filter, and it
is one of the harder ones to
play, but for $25+ it does a few things that work well on bass-- one of those tones being shown by Flea in some youtube practice videos.
Flea also makes it look easy because he has the fingers. There are many other filters on the market, and most of them are tamer and more forgiving. There are a couple filters that I've been able to cop similar tones/envelopes with, but none of them were are thick or potentially speaker-shredding as the FX25-- that tone comes with a price and practice.
One more thing to note is that the FX25 is a band pass filter, so when they top sweeps up, so does the bottom; keeping that in mind and controlling the range of the sweep (ie practice) you can cop some seriously funky and cutting tones. Many of the commonly referred to filters around here are Lowpass filters, so when the filter sweeps up, the lowend still passes, as there is only a single band sweeping the top end; generally with a lowpass, you can just plug in and noodle around without much consequence or any lowend loss. (though there are exceptions, like the qtron and other super resonant filters)
DOD FX25 mod? 
It seems that pedal could turn a speaker cone into confetti.
