...but this one is virtual and offered by Ample Sound. In fact, it's the light version of Ample Guitar M, the virtual guitar for Mac and Windows.
Ample Guitar M Lite is a 670MB reduced version of the Ample Guitar M virtual acoustic guitar (5.59GB). It features 668 samples in 16-bit / 44.1kHz and you can only play on the first four frets with fingerstyle (no strumming here). 5 playing techniques are included (sustain, hammer on, pull-off, palm mute and popping) and you can apply a reverb and a stereo delay.
Ample Guitar M Lite is available in VST, RTAS and AU formats on Mac OS X and Windows 32 and 64-bits. You can download and compare it to the full version on www.amplesound.net.
Have a great weekend!
