I would consider buying this for my PA3x or the new Casio piano I'm thinking about buying. The major music stores don't carry this. Has anyone else tried it on their keyboard? I'm not sure it would be loud enough for a small cocktail party, but would I get a full range, true keyboard sound if I were to use it just for practicing (tired of using headphones)?

Or can anyone recommend a very small amp, that doesn't "color" the sound, I can use for practicing?
