Last night I hooked up my new DOD FX25B Envelope Filter and my new BBE Free Fuzz.

Interesting things happened. i noticed, first, that the envelope filter doesnt like my compressor, but it really likes my chorus. So I couldnt just run my regular sound through it. I had to bypass the compressor. I had it hooked up like this:
comp -> cho -> EQ -> Filter -> Fuzz
Then I tried switching the filter and the fuzz. That's when it got really interesting. The sound that I was able to create using both of them was very cool.

But the filter wouldnt work if the fuzz was in bypass. It was like running the signal through the fuzz pedal made it un-wah-able unless the fuzz was on.

I'm new to bass effects, so I'm not sure what to think. Any ideas out there?
