Thank you sir!
I originally was using send/returns and found that didn't work, so I found a YouTube video showing I needed to use the front end of the amp in the mix, which didn't make sense as running a line into the front end of the amp doesn't make sense when bypassing the preamp in the first place. Works though, and even though the main out is in the channel in on the amp.
I did all the rest, initial backup, firmware update etc. As for the rest, I'm going through and populating the user presets with the amp models I want. I basically made 3 blank templates, pulling all the blocks I don't use like loop, amp cab etc. freeing up the blocks I'll be using with specific amps.
I'm sure I'll be reconfiguring this thing for months as I vet out what it is I want. There's more than 3 ways to do one thing on these so I'm going through trial and error to find out the setup I'll use most. I was thinking after taking all the models I need I'd wipe the factory and call that the home setup and use the user settings for live. Not sure yet.
I did pull all the cab models from the templates as I didn't find one that sounded any good, sounded like they compressed the signal too much when going back into the combo. I haven't had the chance to hear what it sounds like without a cab model in the mixer,
