Hello DonM, like some one have said that sound is a very subjective matter in fact it proves right here you don't like the PA-80 guitar and I think PA-80's nylon guitar is very good http://www.korgpa80.com/pa80/mp3/nylongtr.mp3 and off course I have heard the carlos guitar demo of Yamaha! :-) about the sampler I think PA-80 will soon have a limited sample play back feature! using the flash card !
