I received this amp from Musician's Friend as a bonus when I purchased a Korg SV-1 keyboard. It is perfect as a practice amp or even an amp for small room solo gigs. If you think you're going to drive a full 88 key keyboard or bass at full volume, you will be disappointed. There are three key points that allow you to pull more power out of this amp: 1) pay attention to the gain structure 2) use subtractive EQ and not additive, and 3) get the amp off the floor (I use two milk crates). I just used this amp on a medium size restaurant gig and it worked fine with only minor clipping. The Phonic EQ should only be used to cut frequencies, not boost them – all major EQing should be done before the signal hits the Phonic. I used an old Boss 8-channel line mixer loaded with reverb and delay effects as well as sends from a SV-1, vocal, Roland GR-55, a Digi Tech JamMan, and a Godin Spectrum guitar – sounded great. If you need a bull of a keyboard amp, pass on this. If you're willing to really work with EQ and gain structure in medium room environments, you might like this amp.

I just bought the Phonic MK50 Keyboard Amp, and practiced with my rock band last night. I would expect a 50 watt amp to put out a lot more volume before maxing out. The reverb is so-so, but most keyboards have nicer effects anyway. With the 4-band EQ, I got fairly nice sound quality, but both the clip lights on the individual channels, and the limit light on the output side, come on at fairly moderate volume, and sound will start distorting whenever they light up. If I keep it below clip levels and put it close to me, it's a nice personal keyboard monitor, but needs to be mic'd into the PA to be heard over the guitars. And the mic needs to be positioned to catch both the tweeter and woofer to get the full range of sound.The website, the manual, and even the box all say there is an external speaker jack, but there is not, nor is there a line out, unless I were to tap into the effects insert somehow.The amp seems to be built solid, but not high-end, with plastic corner protectors. There are no side-view pictures anywhere on the web, but the back is slanted both top and bottom like a floor monitor, so it faces mostly up, maybe 60 degrees, fairly good for keyboard either standing or sitting.I rated it good in value mainly because I got a really good deal from MF. At its typical price there are probably other better options, especially if you don't always have the ability to mic to a PA.

MK50 Keyboard amplifier Great for a drum amp

By Brian Dunning

from Pennsylvania

See all my reviews

Comments about Phonic MK50 Keyboard Amplifier:

The MK50 keyboard amplifier works great as a drum amp. I have an Alesis DM6 USB performance drum set. I did crank it up to full volume and had no problems at all except for everything rattlinging on the walls from the awsome bass and the loss of hearing :-). My roommate was downstairs and he said it sounded awsome. He is a very experienced gutar player with extensive knowledge in amps and he is very impressed. The peak and limiter lights do come on but only when I am really 'pounding' on the drums. I play with the input volume at 6, the master volume at 6, and the drum module volume at about 90%. This is more than loud enough without causing me to go deaf. It does come with a power cord which is packed in the triangular shaped packing cardboard piece unlike previously stated by another review. I can't say enough how happy I am with this purchase. Great sound, great features (except for the lack of speaker outs) and an excellent value. I was all smiles as soon as I hooked it up. Rock on :-)
The only problem with this amp is that there is no speaker out jacks eventhough it lists as having them. You could use the headphone jack as a speaker out but, then the amp will be bypassed. The back is trapazoid shaped so you can angle it. The reverb option is kind of weak but, I am using as a drum amp so reverb isn't a major concern. Overall it dials in nicely. I would have given a 10 if it wasn't for the mis-advertising about the speaker outs.
The quality is just unbeatable at this price. The corner pieces are plastic instead of metal but I have no intentions of banging it around. The sound is great. Excellent highs, mids and lows. The cymbals really come to life without any crackle or breaking up. The bass is deep and clean.
You can't go wrong at this price. I would have paid double the price for another amp and not have gotten as large of a woofer.

Phonic keyboard amp MK50

By Terry Schneider

from U.S.A. planet Earth

Comments about Phonic MK50 Keyboard Amplifier:

I have to give a low score due to the fact that I have to send this Christmas present back.
That sucks.
2 channels with 4 bands of EQ. nice reverb
Woofer sounds great for bedroom practice.
Tweeter is bad right out of the box.
Has a buzz in it.
I thought that it was the nice metal grill but further investigation is it is the tweet.
I would give this a 10 if not for the tweeter issue.

Comments about Phonic MK50 Keyboard Amplifier:

Works fine at lower volume. starts clipping at a lower volume than I would have expected, but it's a nice practice tool when away from my studio. I would buy another. It takes up very little space.
2 channel, no XLR. Couldnt expect more for the money. I like the fact that it can be used upright or, and a wedge monitor. Reverb is ok.
I'm using it as a practice rig with a small mixer and bass guitar in it.
works fine out of the box, but i've only had it for 2 weeks. I have 5 power amps, a powered mixer, and 2 Speaker cabs made by Phonic, and all have been great!
can't beat it for the price

    Comments about Phonic MK50 Keyboard Amplifier:

    I'm giving this a 5 based on the quality given the cost (I got on sale). At this price, it was a great deal. The sound quality is quite good for the money. I use it to hear my synth and to practice with a band (not super loud though). The construction while using plastic in places is pretty sturdy. The knobs are firm and made of a hard plastic I believe. And it did come with a power cord.

      Comments about Phonic MK50 Keyboard Amplifier:

      Well. I am not a keyboard player. But I use this to monitor my sequences in a weekly gig. So far it has worked fine (2 years). I am not too picky with my sound, I got 2 Roland keyboard amps and of course they sound better and louder but this Phonic does the job in a more than satisfactory way. I got it as a throw in with a Korg M50, and I am happy I got it that way since I didn't need a third key amp. If you have high expectations go for something else. If you just need to work out your gig I would recommend this one.

      Comments about Phonic MK50 Keyboard Amplifier:

      I received this amp for "free" with the purchase of a Korg M50-61. It sounds loud, clean, and crisp. EQ controls are responsive and distinct. The main point I wish to make is this is exactly the unit the used to sell with a Crate marque on it. Exactly the same as a Crate KR50 with a different brand. Easy to haul, fairly light, fairly tough, nice space for cables under the power supply, dual 1/4" inputs and audio inputs, decent EQ, um, nice flocking. It does the job, and at this price you can get two for 100W of stereo out yer keyboard. Go for it.

          Comments about Phonic MK50 Keyboard Amplifier:

          Considering a new inexpensive practice amp, then look no further. Easily fills a 20 x 24' room with ample sound. May suffice as a gig amp for a single keyboardist. The 4 channel EQ should be given particular attention when first setting up for best sound results. Future buyers should keep in mind this amp does NOT come with a power cord.Uses one similar to a PC tower. You need to supply one. On the plus side is the cabinet configuration of which allows it to be used as a monitor as well as conventional upright placement. Overall, you get decent sound from the Phonic Mk 50.

          Comments about Phonic MK50 Keyboard Amplifier:

          Its pretty decent for what it is. I've purchased other Phonic equipment in the past and have been pleased with it. In general their stuff performs as advertised and has decent features, but does not seem to be super rugged. The stuff I have purchased has been for use in my studio and works great for that. I'm not sure I would plan to take this stuff out to a gig though, at least not on a regular basis. I'm not sure it would hold up to much abuse, but works great for sitting in my studio. This particular amp has decent tones when the EQ is set flat and does have a four band eq, so decent amount of adjustment if you need it. Its loud enough for pracitce in a small band (no drums) but would need something larger for a full band. The reverb built into the unit is ok, not great, but does add a little something if you need it.

          Better than expected

          By Aaron Doucett

          from Massachusetts

          Comments about Phonic MK50 Keyboard Amplifier:

          I received this amp free with the purchase of a Nord stage piano, and it has arrived a few days before the keyboard will. At first I was surprised at the size of the amp, which stands taller than my Behringer 90-Watt keyboard amplifier. The overall weight is around 40lbs, but not ridiculously heavy. Amp has 2 inputs with independent volume control, 3 band eq that seems to work well, and built in reverb. The reverb effect adds just a hint of "roomy" reverb, nothing like a huge hall, so it doesn't muddy the sound much. Among my favorite features of the amp, is the fact that it tilts back about 45 degrees, for a perfect monitor position while sitting. My father tried the amp out with his acoustic-electric guitar, and I was pleased with the sound quality at about half volume (filled a large room) without peaking or crackling. I've yet to try the amp with actual piano-voicings, but for synth sounds, or basic amplification of a line level signal (like an iPod) this should do nicely. I was expecting a product of much lower quality as I got it for "free" but I'd say it is definitely worth the $129 Musicians Friend is asking for it. A good amp for the beginner or someone who does not want to use the "on-board" speakers on their keyboard or stage piano.

          Comments about Phonic MK50 Keyboard Amplifier:

          Pros - overall sound is ok - will use in a small area for house sound and for rehearsals; but for a large venue, it's fine for a monitor only. Very basic design - no fancy, schmancy effects or settings - can usually control those from the instrument.
          Cons - can get boomy when the volume is up, so have to tweak the tone to compensate; then, it can sound tinny - best used at moderate volume. Lacks some relatively inexpensive features as mentioned above - how much extra would it cost to add a real external speaker and line-out jack anyway?
          Pros - 2 separate instrument inputs with their own level control; wedge-shaped cabinet for use as a floor monitor; 4 band equalization/tone controls, built like a tank

          Cons - headphone jack doubles as an external speaker jack - requires reducer plug and shuts off interior speakers when using an external cabinet (would be cool if it had a "real" external speaker jack); no line level output (only line inputs for CD, etc.)
          Pros - may be too early to tell, but so far, so good - no issues
          Cons - none yet

            from Upstate NY

            Comments about Phonic MK50 Keyboard Amplifier:

            This amp might be ok for a practice amp, but it definitely will not suffice for a gig amp. Problems I had: lots of distortion on the 1st channel, but lots of volume. Channel 2 was much clearer but lacked any volume. While playing with my band, the amp kept peaking out at a little over half volume while using a Casio WK200 keyboard. I would not recommend as a gig amp. I sent it back to Musicians Friend and purchased a different amp.

            Comments about Phonic MK50 Keyboard Amplifier:

            it was terrible and disappointing
            it arrived with the innards completely unconnected
            there was a huge puck-like magnetic piece that looked like it had once been glued
            but now undone
            totally unusable
