It’s the same model as the P-145, but without the option to connect three pedals—and it's much cheaper! I used to play the Yamaha P-45, but this model feels like a nice upgrade. First, the piano sound is much better. I'm not sure if it's the improved sound quality of the recorded instrument (Yamaha CFIIIS) or just better speakers, but it definitely sounds nicer. Second, the keyboard itself feels better—GHC with weighted keys makes a real difference. I’m not a beginner, but this piano still meets all my needs, whether I’m playing classical compositions, popular songs, or worship music.
