It's pretty easy to create a simple A,B,A+B selector on the output of the sound card, it just involves picking up a couple of DPST switches (or a dual pole rotary switch), few 1/8" headphone jacks, a little bit of wire, and a small project enclosure (all easily available at RadioShack). Then, a little soldering and it's done. However, you'll get an audible pop if the amps happen to be on when you flip the switches. You might be able to mimimize the pop with a few extra passive components, but the pop will still be there. You could also get crazy: power the box with a wall-wart for ~6-12v @100mA and add a muting circuit, but that's probably getting more complicated that you want.

So, you and linc are converting GTPs too? Seems like I was just about the only one and now you're the third that I remember seeing in a short while. FYI: Mike just put up the GTP motor mount in the store...
