Recording Bass DI and Amp simultaneously with M-audio 2626

[clearitup]

I'd like to record Bass direct amp and Mic the amp at the same time if possible.

 

I have the bass line connected to the front of my m-audio 2626 which provides a preamp. Then, using logic, I have the out put of that file to output on the back of the m-audio which runs to the Amplifer.

 

The issue:

 

Using the preamp colors the tone of the amplifer in an undesirable way.

 

If I don't use a preamp the signal of the Direct In recording is very low /weak and doesnt make for the greatest recording.

 

Any suggestions? Thank you for your time.

To avoid impedance mismatches (which color the sound usually in undesirable ways) when reamping, you should use a reamping device such as these:

Thank you for your reply David!

 

Since I posted this question, I found that a direct in box might be the solution ( such as this: http://www.guitarcenter.com/Live-Wire-Solutions-PDI-Double-Shielded-Heavy-Duty-Passive-Direct-Box-103686903-i1372939.gc)

 

The chain would be: Guitar -> DI box which would split the signal to the m-audio and the amp input.

 

I'm not sure how the reamp compares but I'm going to try and do some research.

 

or just a splitter like this: http://www.guitarcenter.com/Lehle-P-Split-Splitter-Guitar-Pedal-150527-i1326023.gc?source=4WWRWXGP&cagpspn=pla

No, no, no: you already have a DI Box, you don't need another one. I insist: what you need is a reamping device.

 

Where is your already existing DI Box? On your M-Audio 2626: the "mic/inst" button allows to switch an input between a mic preamp or an instrument preamp. An instrument preamp is, in other words, a DI Box. So you do not need to purchase another one.

 

Where you are losing sound quality is not at the input of the M-Audio, it is between its output and the amp input: the amp input is not designed to receive line output levels and impedances, which is what the M-Audio feeds it: the amp input is designed for guitar output levels and impedances. A reamping device brings a line output level and impedance back to the level and impedance of a guitar, which in turn is perfectly matched to a guitar amp input.

 

Hope that helps.

I understand now. Thank you for clarifying that.

 

So I need something like the

Radial Engineering Reamp JCR Passive Reamper or ProRMP™ Reamp

 

Reamping technology seems really neat, I can record both at the same time (amp and di) or I can record the amp at a later state(awesome).

 

 

Just out of curiousity, would the method I mentioned also work? Guitar signal to DI BOX , 1/4 to guitar amp, xlr to m-audio input?

Yes, it should work, but again, the DI Box is redundant. All you need is a signal splitter with two outputs. There's no need to process or transform the signal's level or impedance. Something like this would be enough:
