AmpKit for OS X
Back in February 2011 I reviewed a new iOS Amp Modelling App called AmpKit by Agile Partners, this app has been a great success and 600,000 iPhone & iPad users have downloaded the app. Now due to this success Agile have ported the app over to be a fully fledged OS X app.

  • Includes all the great gear that AmpKit is famous for at no extra charge: 22 faithfully-reproduced amps with 38 separate amp channels, 28 pedals, 28 cabinets and 8 mics.
  • A true native OS X app, built specifically for OS X Lion and Mountain Lion, with snappy 64-bit performance and a beautiful, immersive user experience.
  • Even better sounding on the Mac, with improved simulation fidelity to deliver superb tone for both clean and high-gain play.
  • Breakthrough price: just $49.99 on the Mac App Store (US).
