The signal path has been tested. I plugged in this morning and made sure the guitar was getting to both amps, and the mics on both amps are getting into the interface and from there into the computer. Check.
Now I just have to learn how to play the new songs and record them. The downside of not playing since November though is that it took about two seconds for my fingers to start hurting. It’s going to be rough over the next 18 days.
