Great sound, sound quality I was looking for. I get the sound I was looking for and more. In every setting I have used this amp it kicks but (practice, on stage, in the park, in the mall). I use a Kawia K4, Korg c505 concert piano, Yamaha psr172. I plug my tape deck/cd into this amp and play/sample/record all at once. I do not turn the volumes to max, and I try to only have one instrument plugged in at time during gigs.

The 4 lines in with controls is my favorite feature plus tape in and out.

Sounds good, built good,

I got this baby over a year ago for todays price and it performs well in every situation where I use it

No need for support thus far

This baby is sexy, all the controls on the front.

I purchased this product in Early 2005, as my first Keyboard Amp. Sounded great, real loud, projected the Organ, Piano & Synth sounds of my Casio WK-3500 very well for about 6 months, and then my usage of this product slowed down dramatically. Started up again early 2006, no real problems then either, still very loud tones, would crank it to compete with the guitar, bass and drums. But mid 06' I began to notice a decrease in volume presence and a slight crackle and lack of power.. the 15in speaker/woofer blew out in April of this year. Right now it sounds horrible. Sounded great for about a year. Sounded like noise coming from a big black box, rather than the instrument itself.. know what i mean?

Cool direct out slot, fx inputs and yadada. Never used it other than to play back recordings from the jams which were just recorded and to amplify my keyboard.

Was very easy, plug in the power cable, plug in your instrument, turn on, adjust volume and eq.

Overall, less than 2 years of use. Owned it for 2 2/5th's year, quality began to decrease mid 06'.

If you are careful with it and keep the volume to a reasonable level and direct out to a pa for louder amplification I am sure this amp would last a while.

Never needed any.

It is a black box with a few nobs. It is heavy. Youch.

This amp is OK for organ sounds and even for a bass guitar. It sounds terrible when used with a stereo keyboard using piano or pad sounds. My moderately priced headphones sound much better reproducing piano sounds than this amp.

Would never buy it again. If you only want organ or bass sounds it would be OK. For any type of stereo piano sounds, it is awful, it sounds either very tinny or if you eq to bass very muffled.

Rock and Pop

Havent had it long enough to move it around a lot and test it for different enviroments.

Like all the features . Very nice. Use it mostly for input from a Theremin and it is great for that. 3 octaves above and 2 below middle c.

seems to be on par quality wise with everything else out there and costs less.

far cheaper than other products of same kind.

Have other products from this company. They all work as advertised. No reason to contact them so far.

This amp was great in the beginning when i first bought it. but just about a month later it completely blew on me. now it sounds muffled and far away. i can't stand it so i'm selling it and buying a new roland kc-550.

the four input jacks are great, you can even use it as a mixer if you wanted. the fine tuning in the sound was great before it blew on me, and now whatever i do it still sounds terrible

i can't even talk about the quality....instead i'll sum it up in one word....HORRIBLE. don't be fooled like i was and think that all the other reviews for this product out number this bad one. i'm not lying don't buy this

it's a good price for what you get i guess

N/A

no not really...it doesn't look very cool at all. its just a big black box
