[Harp-L] Amp for Guitar and Harmonica?

[j r <jr_parker_jr@xxxxxxxxxxx>]

Hey all,
Do any of you use the same amp for both electric guitar and harmonica?  Or do you have any recommendations of what might work?
I recently got an electric guitar and I'd also like to start playing harp miced as well.  I'm looking for a practice/small venue amp.  I tested out a Fender Blues Junior on my guitar at guitar center, which sounded great, but after doing some research it seems the consensus is a Blues Junior should be modified before being used for harp.  My budget is maxed at $600, with the understanding I may have to get a pedal or two on top of the amp.  
I don't have any harp mics at the moment, in case that would be relevant to someone's response.  I'm looking at getting either a bullet mic or a bottle o blues.
Also, I realize I will likely end up getting two (or more) amps eventually.  However, budget-wise I'm hoping to get away with just one for a while.
Any suggestions appreciated.
