James, I took your advice & unhooked the 31 band. I only used it on my Jazz Bass for drop D tuning songs so I could boost the signal to match my Alembic so I wouldn't have to reset my whole amp for the different basses. But I was getting a nasty hum with the 31 band patched in, not sure why, it never did that on my old amp. I am currently running my Eden World Tour 800B in Bi-Amp mode & have the SF-2 patched in the Post-EQ stereo effects loop. I go effects send to channel A in on the SF-2 in stereo mode, then channel A out to the high return on the WT-800 & Channel B out to the low return on the WT-800. I was experimenting today & I noticed that both filters on the SF-2 have a slight effect on both low & high outputs on the WT-800. The amp has a balance control so you can pan between the low & high speakers. I would have thought that the channels would be completely seperate in stereo mode on the SF-2. Is it because I'm only going into channel A with the send then out of A & B? This was one of the possible hookups in the manual. I wish the amp had stereo sends as well as returns then I could patch the SF-2 into the individual channels, but the amp only has one send & 2 returns in the post EQ loop. The Pre-EQ loop only has one send & one return.

The Channels are discreet in stereo mode,
If you turn the Direct signal of each SF-2 channel to zero so you are only passing the filtered signal, do you still here the 'crosstalk' ? How are you splitting the post EQ effects send ?
( If it's a 'Y' cord without mixing resistors that might be suspect.)

If you have the time, try putting the SF-2 after the F-1X using the high and low outputs to feed the SF-2 in stereo mode.
I guess you would match the crossover point on the Eden with the setting on the F-1X to make sure there aren't any holes .

I go effects send to channel A in on the SF-2 in stereo mode, then channel A out to the high return on the WT-800 & Channel B out to the low return on the WT-800. No Y Cord. I figured it out though, it has something to do with Bi-Amping on my WT-800. When I take it out of Bi-Amp mode, the cross talk is gone. So the problem isn't with the SF-2. It's not really a problem, the tone is amazing, I just thought it was curious. Thanks for the reply though!

I'm glad your making good progress.
I didn't realize that the SF-2 could take one input in stereo mode . Those little black boxes are amazing!

SF-2 update - After some discussion on the Eden forum (apparently I was the ONLY one running in bi-amp mode) I reconfigured my rig to full range & switched my SF-2 to mono mode. My signal path is Pre-EQ Send to channel A in on the SF-2 in mono mode, channel B out of SF-2 to Pre-EQ Return. Here's my settings for my rig using an Eden D115 XLT & Eden N410 RS speakers.
