I want to build something of a buffered Ric-O-Sound box. It's very simple in theory. Basically... 1x stereo input to 2x buffer to 2x mono output But to have someone make this for me (say for instance Creation Audio Labs) is going to be well upwards of $200... I feel like the concept is so simple I should be able to just do this myself. I am handy with a soldering iron after all. Is this a feasible DIY, and where would I source the enclosure and the buffers? Thanks TB.
