Question/issue: sending OUT2 to the device you're going to Tonematch isn't exactly the same as plugging the guitar directly into it, the impedance is different therefore the quality isn't the same. Wouldn't it be better to use a good quality AB/Y pedal in front of both the Axe and the unit we're going to Tonematch?
Thanks!
You can do that and sometimes I use that technique. I haven't noticed any difference. The input impedance of the Axe-Fx is very similar to a tube amp so you are loading the guitar the same.
