Im jealous, your ABY box should be premium and very good, I still don't need one as I only have one small guitar amp and another small bass amp at home. Which amp do you use?
I use a NUX DI from China, it has 1 input, 1 parallel output, 1 balanced XLR output, 1 unbalanced output, it has 3 outs, the difference between parallel and unbalanced is that the unballanced goes to transformer and could get its db reduced, maybe they did it when you forget your XLR and need to borrow another cable to play in the gig, it handles fine when going to my transistor Marshall MG30cfx (small amp for practicing), the XLR I use when I connect my Bass to the mixer in the church, it has active pickups (ibanez gio crap) and clips the signal easily, so I have to use the balanced and -20db when I connect to the mixer.
This channel has great tips for reccording, if you don't need one, don't waste your money, Im also jealous because in Europe your money is 1:1, for me an euro is 7:1 BR$, our minimum wage on Brazil is 200€ . In example, if you buy a Behringer pedal for 20 money units, for us its like 300 money units. In my situation my Bass signal is really really high impedance and I use 8 meters cable, I need to have low noise signal, my long cable will be a radio antenna.
In my Rocksmith situation, as I said, the realtone cable is quite expensive, instead 20 money, it is like 300 for me, I tried connecting my old Zoom multiefx, but its legacy now, it was bought in 2010, for windows 7, it doesnt have new drivers, the audio gets harsh and had some ripple before I learnt how to reduce in my Zoom the reccording gain and how to use Asio4all drivers (newer generic drivers are better than old focused drivers XD), so I just went to Rocksmith menu "Path/Input", changed the input from Realtone input to disconnected mode, and played my guitar into a Tube Screamer clone, to my Marshall and was happy to play Wasted Years along with RS tabs, they are easy to loop on practice mode, I know that could just not buy the game and the DLCs and just watch a RS video on youtube and play along.
When I didn't know how to reduce the input dB reccord on my zoom g2.1nu, I knew that I as playing bad and I had some lattency on buffer, but the game still scored me 80% . The bass was capturing fine, the Bass RS versions are quite easy, you can score 95%
Anyway, now that I learnt how to configure the RSasio and Nocablemod (lets you use any driver to play RS), I just plug on my zoom input, USB into PC, asio4all and customforge to play CDLC, I turn off the monitoring audio on my zoom, plug my P10 to P2 and play with headphones, no more clipping the signal from my instrument input to the game, I control the volume output to my headphones in game, if I use the PC audio, it has some lattency.
I still have no idea how to reccord my audio to stream playing bass (because I score better than guitar )
, if I turn off the exclusive mode, the lattency is very high and unplayable
