For the last accoustic guitar recording I made I used an Audio Technica 2021 (or similar AT small diaphragm condenser) and a Sure SM57.  I thought the combination sounded nice.  It was a standard guitar, not a bass, so I can't vouch for what would happen in that lowest octave. 

I got the condenser at a pawn shop for about $75.

Clearly that mic is happy being plugged right in to your 1010.  Some of these others will not be.  You can buy a phantom power supply that does nothing but provide 48v to the mic if now isn't a good time to invest in a mixer or dedicated pre-amp.  Samson, AT and various other companies make them.
