I bought this amplifier when I first started playing in ceilidhs all over East Scotland and so far it has lasted a very decent 4 years with me and a few others giving it a LOT of punishment.

The overall build quality of the unit is excellent, it comes in a solid wooden frame and the metal grill covering the main speaker unit is very tough and there are rounded metal coverings on all of the corners - again, making it capable of taking a lot of punishment!

It has a total of 4 input channels (all channels are 1/4" TRS, channel 1 also has XLR input for microphones) all of which are designed for stereo (you can connect two of these together and put one on each side of your setup). Each channel has a simple twist dial for setting volume and there is also a master volume knob to set the overall volume. Also included is the ability to 'shape' your sound, this is done by pressing a small button that enables a further three dials for setting the low, medium and high frequencies of your sound. A small note - I always tend to have this turned on with the bass set a little lower (this speaker really punches out the low end notes ALL the time!).

It is fairly easy to cart about - there is a carry handle on the top and the plug lead fits through this quite easily for transport. It can seem a bit heavy at times (especially after a long gig) so it might be worth attaching wheels to the bottom - the KC550 model comes with this as standard.

Overall, I was more than pleased with this when I bought it and am still using it regularly as part of my sound setup for both ceilidh and practice gigs.
