Recording bass through a small speaker

I was struggling with a bass sound from an audio track.  Tried a lot of eq and compression/limiting but couldn't really get it to sit in the track. 
In my old studio days, I would sometimes record a bass played through a 10" speaker with an SM57 just to limit its sonic range.  I know that the original Fender Super Reverb amps with 4 10's was used alot by bass players. 
 
Anyway, when I remembered this technique, I thought I would try sending the signal through the only amp I own which is a Vox VT30. 
I then read the online post about Guitar Rig vs. Amplitube and decided to check out Amplitube because it has mike placement options.
 
I installed Amplitube Free and used that on the bass track.  I learned that I could move the SM57 around the speaker (a 15") and I was able to find the sweet spot I was looking for off center of the cone. 
So, remembering an old technique and substituting digital technology really helped me on this project.  It didn't cost a dime and I am pleased with the result.

realize that a 57 has a built-in roll off, right at the frequency where the low fundamentals are on bass guitar.

in other words, you're missing frequencies you cannot add with post-EQ.

yes, i do this on a regular basis with my own bass tracks.

i always track a direct line thru a sansamp bass di, and take the 2ndary 'thru' clean signal, directly to my guitar amp and cabinet, which is setup for 'midrange grunge' for the bass.

i sum the two tracks together, to get my super lows clean, and midrange dirty, and blend to taste.

just be aware of lining up the audio waves so that they are together, IF you have too much distance between the mic and the speaker, and IF you have latency issues with your system.

Great thread!

Concerning the sm57 and a 'safe' small speaker, its sonics may be alright (theoretically), though Bat understands this better.  

But even for hip-hop ... your sonic technique seems excellent.  (No one uses a bass like a kick these days ... and skating rinks always raise the kick levels ... the bass doesn't always rule iows)

Mix-wise, I always roll off at 79 Hz (in the mix) ... no exceptions ... since the bass fundies drown the kick.  These are Danzi's live bass recordings as well as Trillion Fender (acoustic) samples.

(Sorry to derail slightly: Regarding getting the bass into the mids, I'm still struggling with that since I've heard some well-gel'd mixes that almost seem like: (1) kick -- (2) bass -- (3) vocals/details/etc. ... ruling the lows, mids, and upper mids, respectively.)
