Sound: I run a vocal mic, a guitar multipedal, and a bass multipedal through it. I can turn it up all the way to compete with a drummer at practice, and it does fine. My vocals are very dry since i'm not running any effects, and my guitar/bass tones come out just as pure as listening to the multieffects on headphones, even at full volume.
Feature: Its just a bunch of volume knobs and a very nice speaker. I never mess with the other additions like the subwoofer out, or the 'shape' thing. It's nice that they are there, but really this thing is about getting a clear pure sound turned all the way up. If you want to tailor the sound later do that on your mixing board or DAW or whatever.
Ease of Use: turn on. turn up. Very simple.
Quality: one of my knob covers fell off but you can still twist the little thingy for your volume. Other than that... it has been out in the rain at a wedding, lived in a musty basement, dragged over the UK, used at all sorts of pickup sessions, and no problems whatsoever. Value: you get what you pay for. These are pricey for the wattage they boast, but I would rather have full on volume at level 10 being clear and piercing in a room than have 300 watts that is all muddy when you turn it past 5.
The Wow Factor: well i bought one. Seemed to me that with the new world of guitar cab simulators, and the need to sing also during practice, i wanted something that can do both. You can't plug anything but a guitar into a dedicated guitar amp. You can plug anything into this. I work with effect emulators, this thing is just here to make them loud. It outblasts my 200w bass amp when I play a good setup on my bass effect into this. It sounds cleaner than my crap halfstack when I use guitar emulators through it. Plus I can sing through it simultaneously and the signals don't cut each other off.
Overall, I needed it because I needed some nice clear volume. It has not failed. I don't think I will ever get another guitar amp, since a nice flat eq'd full range keyboard amp does wonders for amp simulators, sounds so much more piercing and clear at high volume. I don't even play keyboard at all I just love the clarity at high volume this amp gives. I don't think of it as a 'keyboard amp' I think of it as a loud knob that turns what I hear in headphones while programming effect patches into something loud enough for practice without being muddied.
I needed an amp for my keyboard so I decided on this one. Roland is a famous brand in music equipment, especially in the keys-section.
Both processing and especially sound of the KC-350 are very good, I would not have expected in any other way. My keyboard sounds a lot better used with this amp.
And as I found out later, you can also use this speaker as a monitor speaker (e.g. for a singer), a substitute for a guitar amp or a speaker for speeches in small venues, if you like to. The amp also allows you to use various instruments as sources. Besides, you can also link this amp with a second one to create a stereo sound system.
You should remember that this amplifier, is only constructed for being used at home or small stages, but he does that job well! And for home usage its 120 watts should be more than enough! And also with the volume cranked up, the sound stays nice and clear, so small stages are no problem as well.
The KC-350 may not be the cheapest keyboard amplifier on the market, but it's a really reliable, nice amp with great tone. I'd say I won't buy any other amp in the next years.
For such a relatively small amplifier, this incredible amplifier really impresses the crowds. I have loved owning this item, and would recommend it to anyone who needs such an item, despite it falling somewhat behind the renowned Marshall products. It has a few downsides, but these are easily counteracted by the upsides.
For starters, it can be a little heavy at times, but the well-placed handle on top helps a great deal. Another little issue is that it can lose its quality when you turn the volume up quite a bit. The sound otherwise is pretty decent, definitely suitable for anyone putting on a pub gig etc. As a synthesizer amplifier, and that really does show at times. Whilst I'd recommend it as a cheaper option for guitar players, singers and the like, it definitely meets the needs of synth players the best.
The quality of sound drops considerably when attempting multiple inputs. The volume for each input then varies, as if each instrument is attempting to overpower the last. So whilst the amplifier offers a massive selection of input channels, I can't see anyone attempts to put on a fairly professional gig using these to the full.
At the end of the day though, it does work like a dream for those wanting something above amateur, but below professional. It's a extra special dream when it comes to bass!
I bought this amplifier a couple years back when purchasing my Roland SH-201, and did not regret it. This little amplifier really packs a punch, and while being mighty heavy for a little guy like me, is incredibly easy to get around the place (the sturdy handle on top makes it all possible!)
First and foremost, it's a synthesizer amplifier, and I would certainly not recommend it to guitarists above any other amplifier's by Marshall or Orange. However, I have played my guitar through it before and it gave off a fairly strong clean sound. It was only when I upped the volume that things started to sound a little crackly and crunchy (and not in a badass distortion kinda way). It also gave me a fairly muffled sound when I attempted to plug into the mic-channel and sing through my microphone. However, this may just be my experience and others may have had more success with these elements. As it stands though, I would only suggest this to synth players.
In a similar way, I tended to find that plugging more than one instrument in at a time would make for an extremely patchy sound, with both instruments sounding as if they were competing for the amp when played at any reasonable volume. This made the heck load of input channels (each with their own individual volume dials) seem rather pointless to me.
However, I did find this incredibly effective for practising with my Roland SH-201, as it allowed me to pump up the volume (almost to max!) whilst keeping a crisp and clear sound. On the other hand, in a live environment I began to feel that the amp wasn't powerful enough to hold its own as I played with my bandmates. Eventually, I decided to just start plugging into the venue's PA system and leave the amp at home.
As it is primarily a piano and synthesizer amplifier, it does not contain any built in effects such as delay or distortion. It does let you alter the High and Low end frequencies of the sound though, which can come in handy when you're ready for some serious bass!
As an added bonus, it does work perfectly for blasting out some music from an ipod, provided you have the appropriate adaptor cable to go with it.
If you are looking for an amp for home use and small venue gigs you cannot do better than the KC-350. The sound is great, nice bass response. The multiple channels allow you to add other instruments. A
For those of you who are looking for an amp to cover a wide range of instruments, this amp is the king for me. I have a modeling guitar effects pedal (w/ guitar), bass guitar, keyboards, electronic drum kit and an ipod. Each one is able to be connected (at the same time) with great sound. I was, at first, worried about not having two speakers for a stereo feeling. This amp with the ipod alone was able to produce a huge sound just on level 2 out of 10.
Since I have multiple instruments, this amp is perfect. At the store I tested the bass quality with a really cheap bass and it was full of tone. A guitar through a model pedal is great too. This amp is basically a monitor/pa system.
If you are considering buying it, spend the money. You will be happy. This is my guitar amp, my bass amp, my electronic drum monitor and when I have a party in or outdoors this is my PA system.
Without a doubt, a great purchase.
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.
