Boss Katana MK II Amp for Harp?

Hi everyone, 

I have a Boss Katana MK II amp that I sometimes play through (e.g., our annual block party... I'm a beginner and not a gigging player).

Has anyone used one of these for harp? I haven't really seen anything much online in this regard. I was wondering, though, if anyone had and if they had any recommendations around downloadable preset tone packages that are available online. I looked at Boss's online marketplace for these. I found a lot for blues guitar, but not for Chicago-styles blues harp. For example, I know the Fender Bassman gets used a lot by harp players. Maybe I can find a package that emulates that? Not sure.

I'll have to play around until I find something I like, but I thought I'd throw it out to the group in case anyone had been down this road and/or had any recommendations. I'm trying to not re-invent the wheel! :-)

Thanks!

Eric
