[Harp-L] amp upgrade for chromatic harmonica, for jazz

[JON KIP <jon@xxxxxxxxxx>]

A question about amps. For the chromatic harmonica and for playing jazz. While I do occasionally Get the Blues, I don't play them. My site has some samples of the kind of music I understand. Notably absent is The Diatonic Blues. I'm too uptight for that stuff. 

What I have now is something I got from Tommy Morgan which he uses live, a simple/cheap setup consisting of an Ibenez SW20 bass amp, and a zoom effects box. 

With that I get 20 watts, and some EQ (in the amp and in the zoom) and reverb, from the amp, and the occasional wrong note.

I don't need any other effects, I want it to sound  as much like the sound I get in studios, or my home 'studio'. (My messy practice room, with Apple's Logic.) The mic I use and will be using is the ubiquitous SM58.

The problem now is that I can't closely duplicate the studio sound when they release me into the wild to play live someplace, usually after my normal bedtime.

Is that just a pipe dream? How close can I get with something lightweight and not too costly?

Any ideas, appreciated, thanks. 

PS what I do as far as EQ is just knock off a bit of the highs and boost a bit of the lows, nothing fancy.
