Feature:
I bought it for amp models and effects, but I've found myself addicted to the rhythm patterns. Bass, in any key, can be added to the drum tracks. Tuner is handy. I still haven't used the phrase trainer. There's way more here than I expected,

Quality:
It's plastic, yes, but feels very solid. I'm not worried about it breaking.

Desirability:
It's a slick little box.

Sound:
Amp simulation, basic effects, basic presets, all sound great. Some of the presets with lots of effects piled on are blatantly hissy. Cranking up the noise reduction helps some.

Ease of Use:
Basic operations are easy: tuning, changing presets, starting rhythm. Twiddling with all the sub-options of each setting requires a bit of fiddling to remember all the details. Could be a bit easier to use.

Feature:
The built in bass and drum machine is quite nice. You can adjust volume, time, tempo, rhythm, and even the key that the bass is playing in. So you have an assortment of backing tracks to suit whatever guitar parts you are working on. The phase trainer is outstanding. My only issue with it is that if you record up to the maximum time (32 seconds), the compression used to maximize memory takes away too much from the sound. But recording a phrase in 16 or 8 second slices allows for better resolution. What I love most is the ability to slow down a phrase while not changing pitch. You can throw part of a guitar solo or lead on there in a 16 second loop, and drop the tempo up to 50% speed. This allows for a great way to analyze and learn those faster solos you are working on. Then slowly bring the speed up to 100% over the course of time. Works great.

Quality:
The plastic housing makes it seem as if it will break easily. I use mine only on the couch while practicing, so I don't abuse it. I do not think it would take a lot of punishment to ruin this little device.

Value:
It was worth every penny to me. I have made very good use of the phrase trainer.

Sound:
The sound is perfectly fine for usage as a practice headphone amp. Unlike some of the other reviewers, I had absolutely no issue with noise with this using. It mixes the feed from the aux cable in perfectly well, so you can jam along with your favorite bands quite well, which is the main reason I bought it.

Ease of Use:
All of the settings and controls are pretty intuitive. The manual is a bit sparse, but it has not been a problem. It is very easy to configure your own tones if you aren't happy with the presets.

Support:
I haven't needed to deal with Korg on any issue.

Overall:
I do not think I will need to replace this unit. It does what I expected it would as a headphone / practice system.

Feature:
Tons of presets..the ability to Jam with a variety of pre-made rhythm riffs is definitely the coolest feature. It makes practicing a lot more fun and I think it will enhance anyone's playing ability.

Quality:
Good overall quality. Get the AC adapter as it soaks up batteries pretty quickly. It comes with an adapter for hooking it on to a guitar strap, but the hole is too small to fit mine.

Value:
Very good deal for the dough..

Desirability:
I bought it and I'm addicted..

Sound:
Considering it's small size, this one from Korg has quite a lot of features and sounds very good.

Ease of Use:
Very simple use. Has dials to tweak the cabinets, tone and gain in the right places. My only beef is that it lacks a MIDI interface to allow for rapid program changes on the fly. This makes it good for practicing but not for live performance.

Support:
No experience.

Overall:
I'm quite pleased with this one from Korg. If they only made an accessory foot switch for live use...

Feature:
plenty of features that make it easy to plug in and play. If you want to sit there and tweak all day, go buy a podxt (I have this for recording, and the Korg for practicing on the couch or when traveling)

Quality:
Light weight and made of plastic, but what isn't these days. I have no plan of stepping on it and I take care of all my equipment anyways.

Sound:
Great sounds W/ a variety of different amps. It is very cool to jam w/ or practice although the volume could be increased just a tad.

Ease of Use:
It has all the sounds I could want and they are extremely easy to dial in.

Support:
have not dealt w/ them.

Overall:
It's a keeper.

Feature:
I am reviewing this as a headphone amp, not a multiFX. As such it packs a lot of stuff into a little box.

Quality:
Seems a bit fragile but not too bad.

Value:
I bring it along to gigs, in a pinch I would be too embarassed to hook it up if my main rig failed.

Desirability:
I wanted something to jam on informally while couch potatoeing. It is the bomb for that.

Sound:
Presets are so-so but tweakable. I bought it to replace my ancient Rockman for headphone practice in front of the TV. The sound is not suitable for prime time (recording or live) but is fine for what I want.

Support:
Dunno...

Overall:
I own a GNX4 for effects and multiple amps for live sound. This unit was bought to fill a different, specific role. It does that, I see no need to replace it.

Feature:
This unit has more of the modern cutting edge sounds but if your an old schooler like I am you'll fit right in with the Pink Floyd old Santana sounds!! The drums on this unit are also more with the times and plenty of beats to choose from!

Quality:
It's great sound quality but a very delicate unit so you must baby it. It's easy to do just treat it with respect!

Value:
Not a better value ANYWHERE so don't bother looking! At $169.00 retail you will change your whole outlook on practicing.

Sound:
Come on.This is a no brainer. You can't get a better sound or a better value in ANY product out there in this catagory. I own both PX4 & PX4D and I wouldn't live without them.

Support:
Sent me a new belt clip on the house!So far they're good in my book! ;>)

Overall:
I've been using the PX4 for years and I couldn't be happier!!

Feature:
Possibly to many features for the little unit to handle, quality seems to be less then what Korg previously offered in the old PX units.

Quality:
I returned mine, quality inferior to its predecessors. I purchased the unit because I also own a PX3B bass trainer, and in my opinion the PX3B performs much better for my application. The older unit is cleaner, and the auxiliary record function performs much better/clearer on the old PX3B.

Value:
I was disappointed with the PX4D performance, especially when I own and use daily the PX3B with fantastic results. I ranked its value at 5, not suitable for the discriminating user, but it might make a nice toy for a starter guitar package.

Desirability:
It would be a great product if it performed better, I returned the product.

Sound:
A little to noisy for direct recording, but suitable for practice along with auxiliary source. Some fun tones to noodle around with.

Support:
I didn't need to correspond with Korg, however the store I purchased the unit from contacted them and received a very timely responce.

Overall:
I'll wait until Korg pulls this off the market and see what they come up with next, as I said before, my old PX3B is fantastic so I believe Korg will be able to work out the performace flaws in the PX4D. The thing that I like leastly about the unit, is the quality of the phrase trainer, especially the auxiliary phrase recording feature. Normally when recording a phrase off of a CD (Aux Source) with the PX3B, you simply push the Phrase Trainer button once, "Aux" will appear in the LCD window (if you continue to push the Phrase Trainer button, the other recording source options will appear). Then, with the auxiliary source (CD) playing, you hit the "Enter/Rec" button and after the phrase is recorded you can either hit the button again, which ends the recording and begins looping the recorded phrase, or you can wait until the unit records the maximum measures it's programmed to record and looping begins automatically. When the unit is functioning properly, after the unit has recorded the phrase and the looping of the recorded phrase begins, the Aux source is muted and you only hear the recorded loop, which then you may play along with to learn the phrase. When I attempted to record a phrase off of a CD with the new unit, the recorded phrase is garbled, and the Aux source isn't muted. Of course the simple solution for canceling the Aux source is to hit pause on the CD player, but that doesn't help the fact that the recorded loop is uselessly garbled. Since the phrase trainer function of the unit was the primary function I needed, and the noise level made it inadequate for recording, the combined deficiencies make the PX4D useless to me. But as I implied before, it might make a nice Christmas toy for a beginner to get with their starter guitar/bass package.
