HI,
a friend of mine and I are Currently developing a TRUE BYPASS, 3 way splitter, and seperate Mixable return section (at the moment , going to just one output, but this can be changed to stereo LR etc) , Primarily so that i can Run 3 lines of parallel effects, but there are MANY uses for each of the boxes . the splitter can be used on its own to split your signal 3 ways, with no volume loss, and the return box is like a floor mixer, with level controls and foot switches for each channel.
Please get in touch if A) this is something you'd be interested in anything extra you'd like of need in either the splitter or the return .
this is a New project for me , but we hope to be creating some really useful gadgets that will compliment your existing setup , stay Tooned
