Two years after Guitar Rig 3 was released in autumn 2007, the fourth iteration of the software modelling application for guitarists was released by Native Instruments. This time around a combination of an ever increasing workload, little free time and the fact that Guitar Rig 3 was ‘good enough’ for my needs meant it took me a while before deciding to buy Guitar Rig 4.

A special offer by Native Instruments landing in my email inbox a few weeks ago, some free time to play the guitar — after weeks of not touching it — and the ease of buying software online meant that Guitar Rig 4 was running on my MacBook Pro in no time.

This release is the first one that dropped support for Power PC Macintosh computers, around three and a half years after Apple stopped selling them. There is no good reason for this change, Guitar Rig 4 would run comfortably on PowerMac G5s and maybe even the last generation of PowerPC-based iMacs.
