Pros and cons

Pros

The three amp types and three-band analog EQ offer several core tone-shaping options in a compact unit.
Auxiliary input, built-in delay and a phones/recording output cover useful practice and recording scenarios.
Battery-powered operation allows use where an outlet is not available.

Cons

The 4-inch speaker and 7-watt output are a compact practice-oriented configuration, not a substitute for a larger amp when broader projection is needed.
