erm hunter.... I thought the axe-fx only had 2 inputs?!!!
Nope, 4 (or 2 stereo if you want, but you can use the 4 separately). The stereo FX return has a level pot for in and out and can be used as ins.
You only have two input gain controls for the pairs though. So in our case, I had to adjust the gain for both guitars as a compromise.
ah so that's why there are 4 lines of blocks in the software editor!!! can you output the instruments separately as well?
Not sure if that's the reason for the 4 lines, it's probably more display/processor power reasons I presume. Bear in mind that many patches for 1 guitar can easily use 2,3 rows, for running multiple amps in parallel etc.
Axe has even more outs than ins because apart from the Out 1 and 2 (each in Stereo, so 4 outs), there is also the digital output.
