I got one of these over the weekend for a camping trip and I must say, IT ROCKS! It sounds better than my old Crate G-60 practice amp, and it's half the size and power.
It's got built in Boss effects (chorus, flanger, phaser, delay, reverb, and tremolo) and COSM amp modeling (Acoustic, JC120, Vox clean, Rectifier, Marshall stack, and some other clean one) All of the models sound pretty awesome, the only one I can vouch for is the Recto model, it's not the same as a Recto of course, I wouldn't expect it to be, but it's surprisingly close and very powerful sounding.
It has a 5" speaker in a ported cabinet with surprising bass response.
It can be powered either by wall wart or 6 AA batterys (20 hours)
It also works great as an iPod speaker (which I used at the camp ground) and also has a Rec. out/headphone jack which I used to make some decent sounding direct recordings on my Mac.
I give two big
for this little unit!
