Well it's not digital, where it says "
analog modeling" on the amp is the give away
. It's just doing EQ/Gain adjustments rather than actually model different amps/cabs. It's pretty crap no offence.
overturned is right though, if you want it for a pedal collection, go for it. If you're trying to find a magic pedal to right the amps sound, I doubt theres a pedal in the world that will help. If you are thinking of sticking with the guitar, a new amp should be the first thing on your list.
See if you can find a store with one of these...

Its under $500 and its an amp you wouldn't need to replace till you start some serious gigging...
