I posted about GarageBand ’09 about a month ago but just today stumbled across this in-depth review of the new guitar-centric features like amp modeling.

First off, it no longer feels like GarageBand was designed primarily for keyboard players. With a fancy new interface, GarageBand now gives users more visual cues to make adjustments to their guitar amps and effects.

What’s really interesting about the new release is that the amps have been completely remodeled. In other words, Apple didn’t just slap a fancy picture on the previous amp and call it new—at Macworld Expo, Apple told me it was actually proud of the fact that so much work went into the amps.
