I think the title says it all. I've tried recording some bass guitar but it didn't come out great, and a friend recommended that I get a DI unit. Thanks for your help.

No. You do not require a separate DI to record bass with the mobilepre.

Aslong as you are connected directly OUT from your bass to the instrument IN, you should be able to record the linelevel bass.

Im assuming you are just unsatisfied with the sound of the recorded bass? In this case, you can process ITB (in the box) to achieve desired sound. (i.e. run through amp simulation software in a DAW, etc...) If available - IMO, you will get most pleasing results by micing an amp speaker.

Also, you need to make sure you are gain staging properly. Basically, turn your bass gain knob up to the optimum level then the gain knob on your mobile pre up until you are hitting -12 on the mobpre meters.

  • Thanks for your advice, and especially for the tip about gain staging. To be sure, I do not require a separate DI, but if I were to use one, would it have a positive effect? Feb 21, 2014 at 21:49

    Most likely yes - depending on whatchu get. To get real phat in your face bass without micing, I would run into some kind of analog preamp/DI that could accept line levels and overdrive the tubes. If you have a cheap amp/speaker you could try micing that and blending it with your DI. Proper eq and compression can improve a plain DI take, but not replace the results from a solid signal path.
