For practicing, yup, just about anything that puts out sound is good enough, really. I would suggest shopping features first. Do you practice with cd/mp-3? If so, then an amp with RCA and/or 1/8" input would be good. Do you want to hear it mixed with the aux input only through the headphones, or have the option of hearing it through its speaker, too? Some practice amps only send aux inputs through the headphone circuitry, so be aware of that. Would you like to be able to use it as a grab-and-go amp for small get-togethers, too? Maybe a slightly larger unit with a kickback shape might be of better interest to you. Like crunch, but not always? Look for one with selectable overdrive instead of a single gain/volume setup. There are a lot of options to consider for practice amps, but keep in mind that at the end of the day, they are all still just practice amps, so maybe don't drop too much cash for it.
