Okay it goes like this... I'm taking the signal from my bass and splitting it, sending one wire to a pedalboard. The other wire goes not to the pedalboard, but straight to the amp's input. These two paths must needs meet again (theoretically) after the pedalboard, before continuing on to a single-input Trace-Elliot 250SMX. The point is, of course, to be able to switch between pedal signal and straight signal. I have an RFX A/B-Y switcheroo box. This is great for sending to two destinations- like pedalboard and not pedalboard. But how to reunite the wayward wires and bring either/or to the same input? Here's a page with linkage to the manual for the RFX (Rolls) A/B Y box. EDIT: Is this the answer... I send from the bass to the RFX switch box, and from there I split signal- one to pedalboard and one to this thing. I also go to this thing from the pedalboard's output... from this thing I now simply stomp n' send whichever signal to the amp's input. Yeah?... I'm new at this, see. The question may be just plain dumb, and I'm cheerfully hoping to see if that's true! Thanks for reading.
