I own those 2 things. Very different beasts, both hard to tame.
Although I do like the pedal, the
BSW doesn't have a lot of settings that are usable in a band format, outside modes 1 and 2. I did have a lot of fun playing with it on my own

but eventually took it off the board. Now it lies in my studio and I still plug in it from time to time.
The
FX25 is also lots of fun. I have an early 80's edition that a little quirky but waaaaaaaaay funky. Its also off the board for now, I prefer using a later edition FX25B at the moment.
But man... so many filters out there !!!
