Littlebox is an amazing machine for the money.
Even though you want 1/8 out, I would suggest getting dual RCA outs for a more secure connection and more versatility. To go 1/8 in to a recorder, just use a dual RCA-1/8 mini plug adapter cable instead of a cable terminated with a mini plug at both ends. You would also be able to get a cable that would go into the dual TRS line inputs of your MT.
For use with your MT, since some people have said you sometimes need a pad when recording loud shows and Littlebox's minimum gain is 5 dB, you might want to add a switchable 15 dB attenuator.
I have the attenuator and RCA outs on my Littlebox and am pleased with it's versatility.
