All right so I got the new jack from Kiyohiko, and all I can say is man this set up is a great great sound with so much potential and flexibility. One stereo jack with one TRS cord into the Felix which automatically feeds one channel to each eq. Flat sounds great (with one channel phase flipped).
But the real advantage to this set up is it is dead quiet, has no bleed, no feedback (it will raise standing wave feedback on my bass when you get up at blazing loud...easily notched) and thru a 46 MAS cab, really crazy good amplified sound. Thump clarity, very very little piezo annoyance...the phase really tames that amazingly well, dynamics, quickness, the muted percussive notes sound awesome.
The thing about having two pickups like this going thru this crazy felix box, is that the eq has SO much to work and it is such a good eq, a lot of fine sounds can be dialed in easily.
The MAS cabs have 4, 3 inch tweeters pointing straight out (I can turn mine on and off..huge difference) and the Y pickup because of its placement back down the legs of the bridge is darker then a lot of other pickups (and mics) where the high end ultra reality (the EAP had a ton of the excessive high end I mean) can get pretty unforgiving. THe two pickups are really well balanced and when I think I am missing that airy high end from the Remic, I listen from about ten feet away (I have a good looping pedal I use a lot for practice) and I don't miss anything, it just sounds damn good.
Now I really dig the Ischell too and these two blended sound great, but this my main bass I just have the Y on and This simple one cord setup is dope.
I am going to recommend to Kiyohiko that he offer it as an option and although I cant possibly know how it's going to sound on your bass thru another system, this is as close to perfection in amplified bass as I have ever heard.
