Not sure if this is in the right forum, but it's as good a place as any. As I now have a shiny new Yamaha Attitude Ltd II, I thought I'd attempt at making the most of the 2 outputs and short of building a massive rack, I'm having right royal problems. I've bought a little Art ABY box, that when used on it's own, one p/up in A, one in B, I can mix them and get full signal out of both pickups, so I know that's fine. What I'm trying to do however is process them both too. So I'm using one p/up through my Boss GT6B for compression, ampsim, dirt, and other fx, and also eqing out the low end. Then the 'woofer' pickup thru a little Korg AX3B soley for compression and maybe a little eq/amp sim. When I put these between the bass and ABY box set to blend them both, I get full signal from the Korg but hardly any volume from the Boss. I get full signal from each if I choose only A or B, but not both. I bought the ABY box as I tried doing the same thing with a Y cable and got the same result, so I thought a dedicated box would work better. Short of buying a Line6 X3 live (which I seriously thinking about for a while now) which has 2 inputs and 2 individual signal paths that can be mixed together at output, I'm not sure how to get round this. I want to keep my rig as small, tidy, and light as poss, so adding mixers isn't really viable. I'd like to get it all in one bag, bar guitar and amp.
