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.

      Comments about Phonic MK50 Keyboard Amplifier:

      This is a very good amp for small applications. I use it for my baritone guitar and the heavy duty speaker sounds much better on the low end than my regular guitar amp. Problem is, it doesn't have a line out nor does it have an ext. speaker output like the ad says. Even the manual says there is a speaker out but it doesn't have one. Still, it's worth the price and can be a good practice amp for just about any instrument including vocals.

      Comments about Phonic MK50 Keyboard Amplifier:

      Bought this as a gift for my daughter, to use as a guitar amplifier. She is interested in folk guitar and doesn't need effects guitar amps provide. This amp's reverb is adequate. For the cost, it can't be beat, puts out about the same volume as my old Peavey Studio Pro 40 guitar amp. Bass is there but is a little weak, about the same output as with my Peavey. In contrast, my Behringer K1800FX 180 Watt keyboard amp puts out thumping bass (but then it cost 3 times as much). Amp's equalizer section does not work on CD Inputs. You must do this on your device or through a separate preamp. I used Channel #2 input to access the amp's equalizer. For guitar, its bass response is reasonable. I wouldn't use amp for a bass guitar. Amp should work fine for home use as practice amp and for small parties. Because it can be tipped to face toward player, could be used as a powered monitor speaker. So, for the cost at a fraction of similar power output amps, you can't go wrong.

      Comments about Phonic MK50 Keyboard Amplifier:

      I play the bridge output of my Gibson ES345 Stereo guitar through a Electro Harmonix B9 pedal into this keyboard amp and place the amp to one side of the stage. It gives me a keyboard backup without the arguments about arrangements. Players come up during breaks to ask me where the organ is coming from....it's a fun system that makes my solo blues sound fatter..... I don't use it on every tune, but it's a nice addition on some songs...

      It is a wee bit heavy and casters would make it easier to transport. Otherwise, a well featured amp at a bargain price.

          The sound quality is actually pretty decent, but it goes into clip mode if you get the volume no louder than an unplugged acoustic guitar. They claim 50W RMS, but I seriously doubt if you are getting 20 continuous. Very disappointed, useless for most applications. I bought for keys and some light duty acoustic amping, but it is unsuitable for any coffee shop gig or similar.

              Well worth it. Perfect for my practice area. I run two of them for stereo sound. The EQ is perfect for electronic kick drums. I am really happy with the two I purchased.
