...and I'm blown away by the thing. It's the best amp modeler I've tried so far. I've tried HD500/DT50, Elevenrack, Digitech RP360XP and a Zoom G5. My last rig was a G5, Epsi and FRFR. I was happy with the sounds but it was far more complicated than I need. The Mustang IV comes with a 4 button switch. I think if I add the 2 button to go with it...I'll be set. If you think this amp is a toy (like I did) you may want to give it a try.

Ya, those are on my wish list. Nice rig for studio work and I always mike my amp at gigs. I tried one in a store while demoing some stomp boxes and the overdrive was exactly the way I like it for blues stuff. 

I've got to get up to GC and put one throught the paces.

yes, I agree.  I bought three Mustangs when they were phasing out the V1 for the V2, and Best Buy was getting out of the music instrument biz.  I got a killer deal.  I bought two M1 V1's, one for a friend who always wanted an amp; and another for the shack outside of town where I sometimes get to hang out.  Both amps were $49.  I snagged an M2 V1 for $88.  It is 40 watts with a 12" speaker.  I use it at home.  Best of all there is no fizz in any of them.
 
I really like the Fuse software that comes with it.  You can adjust all the models to taste.  Fender also has a site to download many other settings.
 
I don't want to sound like a Fender shill, but I hardly ever get great deals, so I had to toot my horn.
