ART Personal Acoustic Processor

Very easy to use. Dial in effect, use bank A or B and use blend to mix with dry signal.

Very quiet. Experiment with Input and Output gains to reach max volume with minimum quietness. I have owned just about every rackmount and pedal effect. This is as good as my Eventide (that I soled after I heard this unit. Great delays, subdued chorus, great reverb. Even though this says Acoustic, I use it with my electric guitar and it brings forth a really nice guitar sound for use with Jazz, R&R, blues and C&W.

I have had no porblems with the processor, however the ART expternal power supply that comes with should be beefed up where the wire goes into the transformer and the jack.

I would give this a 10. It is little known by most electric guitar players, but when you add the boost effect, it brings out a great tone in your electric. I am an older mature player, not into metal or hip hop. I prefer Chet, Hank Garland, Duane Eddy and I play jazz, C&W, blues and standards. If you can find one, you will throw away all of your previous delay, chorus and reverb effects. I still use a Korg AX30G for tremolo, compressor, wah and rotary effects and a RAT pedal I modified for sustained distortion.

Very easy to use. If you need quick effects, without much experimentation, you can get some great acoustic guitar sounds. Didn't read the manual, just plugged it in and played.

Very clean. As a preamp, I like it. Of course, it doesn't compare to dedicated preamps, but having a clean preamp is a nice feature. Effects quality are good for acoustic guitars. You wouldn't want to run vocals through it, but then again, that's not what it was designed for. It basically has these effects: reverb, chorus, flange, delay, and pitch shift. The pitch shift is unusable (well, I personally wouldn't use it), and the delay is NOT VARIABLE!! That aggravated me. Different presets have different delays, but the settings are fixed. I like the flange with chorus settings... All the effects are decent for guitar. You can adjust the effect setting to degrees where it's very light and just barely coloring the clean sound of the guitar, or very wet and changing the sound significantly. There are "32" digital effects, but all of them are combinations of the effects listed above, or are lone effects. That's kind of cheating, I think. There are really only 5 distinct effects.
Most presets are very usable, I think, except for ones with delay.
No user presets!! Only the factory presets are available. However, they are very easy to adjust with the "Adjust" knob and the "Enhance" know. There is a mix (wet/dry) knob, AND...
A PARAMETRIC EQUALIZER. Now THAT was a nice touch. It's a decent parametric EQ with one knob for the frequency selection, and another knob for the "Q" (width of frequencies near the selected frequency affected by the equalization). It can be used to boost or cut frequencies, and if I really needed a parametric for my guitar, I would get an Art since it's compact and does effects and preamp too.
Preamp has outputs for stereo left/right, and a headphone jack. Also, has XLR outputs, which is very nice.
Overall, most presets are usable, except for the delay ones. Because of the limited patches and no user presets, I'd have to cut the rating on this one. The parametric EQ and the decent preamp are really nice touches, though.

Built like a tank. Steel case, rock-solid solid knobs, it would take a lot to destroy this thing. Needs external wall transformer, though, but that's no biggie.

Wouldn't know. Sorry.

I play acoustic (obviously), and mainly for church, youth, etc... Contemporary style music. I ended up returning it, and getting a rack-mount Lexicon MPX 100 Dual Effects Processor for $220.
Loved the preamp, the parametric EQ, the XLR output, the solid casing...
But presets cannot be chosen via the footpedals. The two footpedals (1) turn the effect on or off(bypass), and (2) boost the signal by a few decibels. That's weak, in my opinion. The lack of user presets really disappointed me. What do you do if you find the "perfect " sound, and you need to call it up really quickly? Twiddle the knobs until you think you've got it again?
Some guitar guru recommended it, saying it was the best of the acoustic pedals, and he's probably right in terms of clean-sound and quality of construction. It's clean sounding, well-built, but limited in it's effects. It tends to lean towards the "don't totally radically change the sound" kind of effects, whereas some of the other acoustic pedals sound really artificial. I looked at the Zoom Acoustic pedal (50... 50 something...), and the DOD Acoustic One (nice, but it was a little noisy. you can relaly change the sound of your guitar, though).
If you want something to color your sound a bit, sweeten it up, and you don't use delay, then you might want to try this unit out. I liked it, but it didn't fit my needs, and it was a little pricey.
If you want something to give you cool effects that color your sound alot, then the DOD Acoustic One or the cheap Zoom acoustic would be better.
Or, start acquiring rack-mount gear, like I am.
