Probably the worst sounding keyboard amp I ever tried. I plugged the PSR-3000 into one at the local music store, and it was just awful. The owner of the store, who recently passed away, said "What did you expect? It's just a practice amp for guitar players. I sell them mainly to music students who use them in their bedrooms and garages to practice. They're fine for that, but that's what they were intended for."

If you're looking for a high-quality, lightweight amp, you should seriously consider the Bose L1 Compact - or better yet, a pair of them. Bose, IMO, has always been the standard bearer in the sound industry, and very, very few exceptions, the L1 and L1 Compact have been the mainstay for nearly every arranger keyboard player I know in my part of the world.

All the best,

Gary
