Hey, what is it that you find the NUX Studio mini doing for you? I've been interested in them.
Primarily to make me look like a 1st class bass player.
I use a NUX Mini Studio to dial in a bass cab (via IEM's) that's closer to the tone in my head. Anything that helps this process (tone in my head) with IEM's is a win in my book!
For the last Thursday's evening service (and Sunday's services), I switched from the Ampeg SV410 + Tweeter setting (which is THE loudest bass cab it has) to the the EDEN 410.
And if you're a guitar player (which I'm not), it can also be used to get electric cabs & acoustic IR's.
