I've had a Loudbox 100 for a couple of years. Great little (size-wise) amp that doesn't color the sound of your guitar. Plenty of power for smaller venues Nice eq on both channels; works well as a stage monitor, too. Would be nice if it had 2 mic inputs, but that's a very small deficiencey as far as I'm concerned.
The Loudbox mini wasn't available when I purchased the 100 so I never had a chance to compare directly.
