After using a Palmer DI box with a small laney tube amp, i wanted to get rid and go for a 'light' setup. This means getting rid of the amp.
So on first plug in, its far better than any sounding guitar going straight into a mixer (sounds horrible), however through this pedal it does sound more like a guitar amp.
The different settings, the changing of 'cabs' just changes the EQ for that setting.
for eg, a small 10" cab is going to have less bass and more top end, and a 4x12" cab is going to have much more bass. The pedal basically replicates this, and it does it fairly well.
I have only given it a 4 for sound initially because its taking a bit of getting use to, and anyone would need to spend some time, tweaking this pedal, and also other pedals like overdrives or distortions to get a sound your happy with.
Its not so much plug and play like a guitar amp, but this is the closest you will get for the price.
As for Mooer pedals go, i have been a few of their others for a year now and they last well. 5 star for quality.
