Hi all, another probably dumb question from this recording newbie. I want to record my bass signal directly into my computer through a usb interface, while also hearing myself through my amp/cab rig.

I tried directing the output of my interface to the input on my amp (TH 500) and it sounded awful, the line was full of noise at all freq. I was using TRS cables. Then I tried putting the send line into the input of the usb interface and the sound was less degraded, but still low-fi and had too much noise.

Right now I think I have two options. I could either buy a DI box and run the balanced out to the interface and the unbalanced out to the amp/cab, or I could try running the amp's XLR out to the usb interface input.

I'm just looking for some confirmation as to whether I'm on the right track. I don't have studio monitors yet and don't like recording through headphones. I like the sound of my rig.
 
Yea I find it's a great amp for the money. Nice mix between modern and vintage warmth with the Aguilar 4 10 cab. I hope this works. I don't know why running the output from the USB interface to the input on the amp using a balanced TSR cable produced so much noise. What you say makes sense and I'll try it first thing tomorrow.
 
Without having info on your USB interface, it is hard to say what the issue is... Assuming it has an XLR input though, I would go from the XLR out on your amp to the XLR input on your interface, or mixer / interface etc...

Mind you, you are running a MUCH nicer amp than I am, but my rig goes like this...

Guitar cable from bass to input on amp (Crate BX100).
XLR from XLR out on amp to 1/4" mono on mixer. Main on amp controls volume from cab, and mixer controls level going to interface.
USB Audio interface connections between interface and mixer with stereo RCA cables.

I can play with the mains up and hear through the cab, play with the mains down and mixer phones / control room volue up and hear through my phones, and both ways I can record. A straight interface won't do that for you.
