Good question. Short answer; shouldn’t be a problem. Bear in mind that your guitar amp has a guitar eq on board. The frequency selections may not be the best for bass, so a neutral setting may be the way. If you’ve got a good eq pedal, like the 10 band MXR or something, you may do well with something like that in the chain.Thinking about using the D.I. out on my Marshall TSL100 into my interface for recording bass. Any reason not to do it? Just trying to avoid buying a bass amp if I can get away with it.
I have an old beater combo cab, with a dead head that’s been pulled...works well for me for experiment duties....Thanks Don. I do have the MXR 10 band in the loop. I'm planning on getting a small bass cab at some point to play through, maybe a 1 x 15.

Yeah, I know about the traces leaking voltage on the main board causing bias drift. Mine is still rock solid. BTW, everyone should have a TSL100 (there, I just made the price jump on them)! Awesome amp for the money.I have a TSL100. I've never used the DI Out on it though. I just wanted to say I have one
This amp is known to have issues. Not sure if the DI Out has any known problems that can arise or not. AMS would though.
