I put the PSR2000 to work today on its first assisted living job (1 hr show) and it performed beautifully. With an audience of only 40, there was no need for amp and speakers. I created a disc with just the material I use for such jobs so as not to have to go thru tons of material to find a particular song. First time I used the harmonizer too...and it was very satisfactory, but not quite digitech.
Tonight my duo will do a country club valentines party and I will use the 740 (with full amp and speaker set up) only because I have not programmed all our material on the 2K yet.
Since discovering these two light-weight gems, I can't tell you how much easier it has become... not to mention the styles, voices and mixes which have enhanced the overall sound.
