Any recommendations for small bass amp?

I doubt you'll find a tube bass amp for $350.00. Best to just try out whatever you can - especially if you plan to mic it for recording. The low end combo's out there are all over the place as far as features, low end, hiss etc. goes. Best to try as many as possible when you're in that price range to find out if one will produce the tone(s) you want.

My opinion... don't do it. Buy this and stick with DI.

Well this is the best bass amp I know of for under $350 (I have one - it's pretty good for small live situations). But I haven't had good luck miking it. But I wasn't using a bass specific mic. I have a Shure Beta52a now, though, and might give it a try. But miking a bass is a different animal than miking a guitar amp. If you have a buddy with a bass amp I'd suggest you borrow it and give it a try before you dump a bunch of money into it. You might be surprised how many top producers with access to all of the mics and amps they can get their hands on still will go DI on the bass.

A couple words of advice for you Marcos.

1:  Be very mindful of proximity effect when you mic a bass cab.

2:  Pay close attention to your mid-range when you mic the cab.  You're always gonna get plenty of bass....position your mic where you LOVE the mid-range.

3:  Split your bass signal so that you are tracking both direct AND through the amp.  Because you can blend the two (be mindful of phase, as the DI and MIC signal are often out of phase with each other), or you can use the DI signal to re-amp the bass track should you decide at mix time you hate what you captured.

4:  If you don't already have the Sansamp that Dave is suggesting.  Get one.  After you spend a few months fussing with bass amps, you'll probably discover that DI through the Sansamp REALLY IS killer and super simple.  :o)

I do both....or either....depending on what the bassist wants.  But MY bassist has a wonderful 73 Ampeg SVT, and all he ever brings for tracking is his Sansamp and a bass....

Thanks for everybody's input.  I have experimented the DI mixed with miked amp technique.  I've played around using a smaller tube guitar amp and DI with some nice results.

I'm not too warm and fuzzy with all the DI boxes and tube emulators or amp sims.  I have a closet full of them from trying to get that tube guitar sound.  The money I wasted on these devices would have gone a long way towards a real amp.  There is no substitute for the real thing IMO.

Thanks Craig.  These look interesting, especially the Ashdown.

I purchased the Ashdown amp.  Should be here in a few days.  Even with shipping it cost right at $350 - my target price.  Will post some music with it when I get a chance to record.

Received amp and love the way it sounds. 

Here is my first recording with it.  http://forum.cakewalk.com/tm.aspx?m=2108279

Miked with sm58 centered on grill about 2 feet away.
