PX4:
Features
The Korg PX4 has something close to 120 effect combinations. It serves as a multi-effects processor, amp and speaker cabinet modeler, headphone guitar amp, rhythm machine, jammer/looper, and so forth. The presets presets are quite good. I especially like the UK'80s preset and the various guitar synth presets (synth, organ, flute).
I find the PX4 to provide excellent sound quality. I have read a few user reviews that indicated the sound quality was not adequate for studio recordings due to noise and so forth. Perhaps it is not adequate for professional studios, but it is more than adequate for home studios. The only time I hear noise, hiss, or signal degradation is through the wireless headphones. However, when connected directly to my computer's sound card, the sound is pristine. The only exception is when I am using a high gain preset and I turn my strat towards the computer/monitor--but that is a single-coil guitar pickup issue, not a PX4 problem.

High-quality Effects Utilize "REMS" Modeling Technology
The PX4D contains 158 effects that deliver vintage amp sounds and much more. From high-end tube amps to rare vintage amps and classic favorites, the 25 amp types faithfully model the amp sounds sought after by guitarists and bassists from every genre. The 23 cabinet effects that reproduce the acoustic and structural resonances of a speaker cabinet were created especially for the PX4D. The creative possibilities are limitless - you can even combine a guitar amp with a bass cabinet.
In addition to standards such as compressor and wah, numerous realistic modeling effects are available in this Pandora guitar effects processor, that deliver a highly versatile range of tones, including:
Pickup modeling that transforms the sound of a single-coil pickup into that of a humbucking pickup (or vice versa)
A guitar (bass) synth that lets you play synth sounds
An intelligent pitch shifter that automatically harmonizes with your playing
A talk effect that produces the impression that your guitar is speaking
A slow attack effect that creates violin-type swells
A feedback effect that allows feedback playing techniques that are normally only possible at high volumes
A rotary speaker that changes speed in response to your picking or fingering dynamics
A fretless bass effect that simulates the distinctive sound of a fretless bass
Many more that are ready for your use
200 Programs to Select
The Korg PX4D provides 100 preset programs covering a broad range of styles including sounds of famous artists. You can also create and store 100 of your own user programs.
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 simple to adjust amp types and parameter values, and the PX4D guitar effects processor also has 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 bass patterns, it becomes 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 onto the PX4D guitar effects processor 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 will 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 multi-effects processor's Key Transpose function to change the pitch of the song upward or downward by as much as one octave. The PX4D also contains a Bass Canceller function that erases the bass sound from an external audio source so that you can play and hear your bass along with the song.
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, with icons representing numerous functions that are immediately recognizable. The display uses a semitransparent LCD so that characters and icons are lit up when backlit, providing a very distinctive appearance. The unit also comes with a strap holder so that you can attach it directly to your instrument strap.
both are shitty digital effect shit.
Ofcourse it would take a much more space cause I don´t have equipment at home to do good circuit board.
Well, my guitar sounds so good now, so I can wait easily some months and try to make some money, but my goal is buy KORG PX 4(D) soon, and try to survive with that some time.
