Korg A3

Multi effect guitar, 1U, digital 16bits/37khz (techno late 80s), with everything you need for the 6 strings: compression, distortion, exits, delay, modulation, reverb. Several variants in each CATEGORY.
The effects can be as chains in the order fixed by the 20 tendon ducts available. A card reader can save its patches (RAM card, useful before battery change) or increase the number of chaining and to bring new presets (ROM card)
100 core memory, MIDI in and out, by CONTRL program change to call the presets. Sysex also has to save on PC, or load the contents of ROM cards (now unavailable). See http://www.korgaseries.org/.
Between mono jack with feedback (direct out) on an output jack (very useful). SETTING THE level.
2 stereo output jacks for sound.
2 jacks for expression pedals, or change incremented by preset / dcrment.
one between the pdalier ddi korg FC6.
Not bad quip even today. C'tait high-end almost 10,000 bullets poque (output to 1989).

UTILIZATION

Simple enough, just shipping heavy but acceptable: you must juggle several buttons Different. SETTING THE paramtres by the knobs are a little tour prcis (the RESOLUTION is often quite coarse). To edit a preset, you have to press edit parameters. to review the values ​​dj programs, you have to press select display, otherwise it is in a vacuum and ds as you touch the knob it is he who sets a new value.
But even when a will because there is no effect by 50 paramtres and trs is good.
The manual is available online and in sufficient gnral. Some tips are not (such as finding the factory presets APRS battery change if, like me, you've lost everything APRS waiting until the battery is completely flat). See http://www.korgaseries.org/.
Not a great note, but no matter, it is not for you has the achte.

SOUND QUALITY

Old technology, but the characters. Not super transparent yet enjoyable. I bought this machine for the sounds, especially the big plus: the delay modul. This variation of time limit is not rpandue trs in multis, whereas a difference. U2 fans, you will be able to get closer trssrieusement the guitar sound in three dimensions of the edge (it uses dlais TC2290 and korg SDD3000, modulated, but much more expensive on the market of the used). The A3 is part of the rack to the edge, especially for the sound of "mysterious way", out of the ROM card SPC-01 guitar.
I like the phaser too. The reverbs are good too, but I admit that this is the time limit that motivated me. A time limit module it is enough even.
Ct saturation is a multi, but I still even t surprised. It seems that the ROM card (including SPC01) offer superb sound saturated. Must try to load the SPC-01 via MIDI.

OVERALL OPINION

When I heard that The Edge used an A3, I looked for and voila: 130 euros six months ago, in perfect state. It appears that the plugs are fragile, but is resolder. For cons, I fear that the TRS mini switch with knobs and the display Intgr let me go because I do not know if we can find spare parts.
Here the price quality ratio do not want to say anything, the machine has more than 15 years. It is primarily for its achte spcificits. If it is to have a super modern, multi trs clean, no intrt for the A3.
I use 90% for dlais (module). I looked for multi able to do, and my surprise, found almost none: line6 echo pro (only time limit), Boss GTpro (quite expensive). Ms. factory sounds TC G-system does not seem to offer. incredible!
