Okay, I entered an acoustic intro into the latest collab HERE. This was recorded using an SM57 into a 2nd Gen Scarlett 18i8 and is the "reference" sound below.
I've just got an Audio Technica 2020, one of the recordings (A or B) was done on my 2nd Gen Scarlett 18i8 and the other was done on my 3rd Gen Scarlett Solo that I use at my holiday home, I used the AIR circuit. Which one do you think is the 3rd Gen with AIR activated? And which sounds better to your ears? They were both recorded using a Sigma 000ME+ but I can record somemore on a Yamaha FG411c instead (Jumbo) if you want.
I have a couple of acoustic guitars with piezo pickups. I've tried on of them into my Scarlett 18i8 via my Line 6 G10 wirels and it doesn't work, the output on the guitar does work with a cable direct though.
