Donny,

I use this when I'm supply teaching in music. Don't need it for my keyboard as onboard speakers work well in a classroom. I do, however mostly use my Digitech and my acoustic electric Taylor and this little amp is really great!

God Bless,
Don

uncle dave had one of those if I remember correctly.....
it's almost 2x as heavy though. Great little amp for acoustic work mostly.

Guys - I have a Crate TX50DB which has a single woofer and a 7 amp hour lead acid battery. This one appears to be about the same size/shape as my Crate. The Crate is a great amp but is heavy at 32 pounds...looks like the weight on this one is only 16 lbs. But the lead acid battery adds about 5 pounds to the mix which is not a factor here...this one is a bit more expensive than my Crate too...looks like it is getting some good reviews.

Yes Randy good reviews....kool amp to just keep in the car for small NH's, or cocktail hr gigs etc,...

or use the AC adapter also....

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

Why not just use a portable AC pack and run your regular powered speakers or arranger keyboard if no AC is available. Remember your audio source would need to be battery powered as well.

Not sure if the following product is compatible, but does say it works with musical amplifiers.

I have a 1,500-watt inverter on my boat that can run my entire rig. It's a modified sine wave, though, not pure, which I found makes no difference with anything other than some electric motors such as fans. Everything else, including my microwave oven works on that inverter just fine.

All the best,

Gary

I'll stick with my 2 HK Nano 600's best sounding PA I ever used.
Its like a Swiss Army knife on stage for any scenario.
