Behringer K900FX Ultratone Keyboard Amplifier (90 Watts, 1x12 in.)

Feature:
Sounds good, the digital EFX are nothing special but they are quite useable. The reverbs add a lot to the overall sound when used as a mini PA. The speakers seem matched well to the amplifier, all in all a nice package especially for the money.

Quality:
This seems more solid and reliable than some older Behringer equipment I have used. It's not top-line but it doesn't cost like top-line either. All in all a good value.

Value:
Good "bang-for-the-buck" and very versatile.

Desirability:
It's well designed, compact and fairly lightweight. sounds good too.

Sound:
I use this as a mini PA for solo gigs as well as a keyboard amp, acoustic guitar amp and the occasional bass amp (at moderate volumes). It does a fine job with all these applications. When set on the ground I usually have to roll off some low end and all your instruments have to use their own EQ's and pre-amps because this is (other than the low-imp mic input) a line level only device with only a 5-band graphic EQ to shape the overall tone. If you can live with that compromise this makes a fine little swiss-army knife of an amplifier.

Ease of Use:
Very EZ to use.

Support:
Haven't dealt with the company so it's hard to say.

Overall:
Again, good "bang-for-the-buck" and very versatile. I am a little wary about the reputation that Behringer has gotten for much of their stuff but it seems a good value even after 10 months.
