I was thinking about running two signals, but I don't have the cash to be buying another amp. I was thinking I could build a splitter to plug my bass into, then run one wet and the other dry and at the end have another box to combine them. I was also thinking of building a blender into this combiner box so I can get one line higher than the other. Before I start really thinking about doing this does anyone know of a company that already makes this product?
