Product Description

82 Effects Optimized for Acoustic Sounds
The PX4A contains Body effects that model the resonances and vibrational character of great acoustic guitars. Aspects such as guitar construction and body size are modeled in painstaking detail for numerous guitars, ranging from famous brands of the past through today's leading-edge manufacturers. The direct sound from piezo pickups can tend to have a sterile character, but the PX4A's effects add the distinctive warmth of resonating wood that is typical of an acoustic guitar, producing an extremely rich and natural sound.

The effects of the PX4A extend beyond the conventional boundaries of the electric-acoustic guitar to include models for resonator guitar, a newly developed banjo, and nylon-string guitar - you can play a wide variety of acoustic sounds using just a single instrument. There are also mic' effects that simulate the sense of space and depth achieved by mic'ing an instrument. With the PX4A, mic-ing techniques that require years of experience and knowledge can be easily utilized by anyone, delivering superbly rich acoustic sound even when using a line output. There are also numerous other effects, ranging from standards such as compressor, limiter, echo, delay, reverb, and chorus, through distinctive effects such as a twelve-string effect that reproduces the sound of a twelve-string guitar, and even a drone effect that simulates the drone tones of ethnic instruments such as a tambura. With a virtual infinity of possibilities that still preserve your natural acoustic sound, the PX4A is the ideal choice for anything from home recording to live performance.

100 Programs to Select
The PX4A provides 50 preset programs, covering a broad range of styles, including sounds of famous artists. You can also create and store 50 of your own user programs.

Auto Notch FunctionThe PX4A's Notch effect helps curtail the feedback or howling effect that can be a problem for amplified acoustic instruments. There's also an Auto Notch function that automatically detects the frequency at which feedback is occurring, so you can perform with the best acoustic sound at all times without being troubled by feedback.

Amp-like Ease of Operation
The user interface is knob-based for intuitive and easy use. Frequently-used parameters, such as the amp type, have their own independent dial, and the tone controls can also be adjusted as easily as on a guitar or bass amp simply by turning the knobs. The value dial makes it a simple matter to adjust amp types and parameter values. There's also a TAP button that you can use to set delay times or the tempo of a rhythm pattern.

100 Rhythm and Bass Patterns
The one hundred built-in rhythm patterns cover a broad range of styles that include rock, jazz, funk, blues and dance music. The PCM sounds used in these patterns produce realistic accompaniments that are fun to play along with. There are even Bass patterns that let you specify the key chord, so you can practice any style of music while listening to a full rhythm and bass line. Since you can use the effect programs at the same time as these patterns, this is a great way to practice your picking, improve your rhythm or develop your sense of pitch. You can also make Chain Pattern settings to combine up to sixteen different rhythm patterns.

Built-in Phrase Trainer
You can record up to 30 seconds from an audio source such as a CD, MD or MP3, and play it back repeatedly (looped) at a slower speed without changing the pitch. This is a great way to learn complex or rapid passages by ear, since you'll be able to hear the phrase slowly. You can also record a phrase that you play yourself along with the built-in rhythm and bass accompaniment, and then practice soloing over the top of it.

Combine Your Playing with an External Source
You can connect a CD player or another external audio source to the AUX IN jack, and use the Key Transpose function to change the pitch of the song upward or downward by as much as one octave.

Semitransparent LCD for Superb Visibility
The LCD that displays the names of effects and programs is backlit so you can read it easily even on a dimly lit stage. Immediately recognizable icons represent numerous functions. The display uses a semitransparent LCD so that characters and icons are lit up when backlit, providing a distinctive appearance. The unit also comes with a strap holder so that you can attach it directly to your instrument strap.

zZounds has verified that this customer bought this product from us. "Great Acoustic Sounds"
Sound: I don't know what people are hooking this up to or what kind of cables they are using, or if their house is directly under huge power lines, but I get absolutely no hiss. I'm using shielded cables, but nothing fancy. I'm going guitar--PX4A--Old Peavey stereo mixing board--Mac Garageband and I get no hiss...to just play through headphones, or record. This box truly takes the piezo edge off my acoustic-electric. I don't even bother with additionally mic-ing my acoustic-electric guitar anymore. Feature: I originally looked at this for the 12-string simulator. I don't really care for that sound and use another tweaked setting for that sound. When I heard the the rhythm and bass patterns you could play along with (100) and the fact you could select the key--well, that was it--I pulled out the plastic. I've had no regrets. There's a lot to keep you interested and playing your guitar on this thing. Ease of Use: It's pretty straightforward. Just by the fact that it does a lot of things, well, you have to get to know how to navigate it if you want to utilize it all. Most times I just want to tune up, use a couple of acoustic guitar pre-sets and maybe tweak volume or reverb level, and that's very straightforward. Quality: I do notice that sometimes, while I'm playing, it loses the setting it's on and goes back to no effects. In that case a push to the next effect and back works. Value: It does a lot more than a Fishman Aura. I believe the sound it comparable and it does a LOT more. The Fishmans are guitar specific and don't even have a tuner...and they cost more. Manufacturer Support: Haven't used it. The Wow Factor: I'd buy another one if it were lost or stolen. Overall: I just have to figure how to have it accessible, yet out of harms way if I do a solo gig. A stomp box may be of more utility in this setting.
Style of Music: C,S,N,Y Eagles, Clapton, Beatles type stuff

"FANTASTIC HEADPHONE AMP! NO HISS!!!!"
Sound: I am using the PX4A with a Yamaha Silent Guitar (nylon) and I am totally thrilled to get such a high quality headphone amp at such a low price! Others who have reviewed this item made note of hiss. I will also note that SOME headphones cause the unit to hiss, but if you experiment with different headphones, you will find that IT DOES NOT HISS with some headphones. I find it works superbly with my Shure E3's, Fostex T-10's, and my favorite headphones to use are my Koss PRO35A's (because they sound great and allow me to hear what is going on in the room). The PX4A makes a loud annoying hiss with my stock Ipod earbuds and my Panasonic earbuds. Feature: The reverbs are absolutely fantastic! I am extremely picky about reverb - I refuse to use most reverbs because they make my guitar tone muddy. This is not the case with the PX4A - The reverb sounds are lush without being muddy. There are several reverbs to choose from - I go with ROOM2 - they are all fully adjustable for mix and depth. There are several acoustic guitar modeling EQs to choose from. It is very nice that they gave us BASS, MIDDLE and TREBLE dedicated knob controls on the front of the interface. (I have not tried any of the chorus's or delays yet - so I cant comment there) Ease of Use: I found that the interface takes some manual study to figure out how to do things. I was comfortable with the interface after about 10 minutes of playing around and studying the manual. Once you are familiar with the interface, it is easy to adjust the various parameters. I really appreciate having the percussion options, but wish they had put in some conga loops instead of all trap set. You can adjust the level of the drums and cut the bass out if you prefer. Quality: My only problem with the quality of the unit is in the ON/OFF switch. It feels cheap and I am very careful to treat it with great care. Value: I am amazed at how great the sound of this tiny unit is! The reverbs in particular are exquisite! I would have no problem using the reverb for recording or as the main reverb in a high quality PA system. I think it is worth way more than its retail price - a RARE find these days! Manufacturer Support: no experience The Wow Factor: It is so tiny! I have it velcro-ed to my guitar. Overall: As long as the ON/OFF button does not break, I expect to happily use it for many years. The only thing that would entice me to replace it is if Korg came out with a newer version that had conga percussion clips. (Plus the jazz percussion clips are pretty corny sounding - more of a shuffle than a jazz swing feel - so I would appreciate if they could upgrade the jazz percussion clips)
Style of Music: Fingerstyle jazz, traditional bebop
