Alesis has introduced its new GuitarFX Processor, a floor multi-effects unit, which puts powerful effects processing technology beneath the feet of guitarists worldwide. GuitarFX is a full-featured DSP toolbox designed to give guitarists incredible-sounding distortion, amplifier modeling, modulation effects, delays and reverbs--all in a compact, easy-to-use pedalboard for stage and studio applications.
GuitarFX's extremely intuitive user interface delivers Alesis' DSP technology in the form of 100 Preset/User programs, taking guitarists from high-gain distortion mayhem to subtle overdriven sounds, modulation effects, lush reverb and more. Each of GuitarFX's 28-bit effects and amplifier models were carefully chosen from Alesis' extensive DSP arsenal, and can be completely customized via simple front panel controls.
Large Increment/Decrement pedals and an expression pedal input make GuitarFX perfectly suited for live use, while a built-in auto-chromatic tuner provides for fast tuning on stage; battery or 9VDC operation means GuitarFX is ready to travel. GuitarFX connections include Guitar input, Stereo Line/Headphone output, and Expression Pedal input.
The GuitarFX is covered by Alesis' full warranty.

Alesis GuitarFX 24-Bit Multi-FX Guitar Processor Reviews
9 out of 10
"Damn Good Little DSP Unit"
Feature:
It has very good presets. I use the presets, and I get a good sound.
Quality:
It's plastic, but it's also $69. What do you expect for $69? Do you expect it to be built of Titanium or even steel or alunimum for $69, for God's sake? Don't slam your boot down on it, and it won't break. I use it at home, and use Boss pedals when I play shows. It won't break at shows if you are wearing deck shoes and don't have a stomp like godzilla.
Value:
Everyone wants the best there is in the world, and then say "I'll give you 5 bucks for it." People make me sick.
Desirability:
I like the blue color. At least it's not some sickening silver or something hideous. I think it's sexy, with lots of sex appeal.
Sound:
It sounds fine to me. It sounds like the DSP processor that it IS. I read some of the other reviews here, and I don't follow what they're saying. It sounds comparable to Boss and other units that utilize DSP. These people expect it to sound like archaic equipment manufactured in 1969, but if they want that type of scene they should save and buy an original Fuzz Face or whatever. It gets a good MODERN (Emphasizing MODERN) sound for electric guitar, period. I think the chorus and overdrive sound fantastic myself.
Ease of Use:
It uses presets, as stated. There is not much to using presets. You choose a preset, and go with it. It's not the type of thing you program. You select a preset, and work with it.
Overall:
I like it myself. I don't know why Alesis stopped making it.

"Ok, but no Distortion"
Quality:
Seems reliable enough to be at a live gig.
Value:
It's set at a good price but the factory presets suck
Sound:
It has good effects but really lame distortion. It's not a pedal if you want the heavier distortion that modern metal bands are using.
Overall:
The pedal needs better distortion settings. It also has a crap load of hiss with the Noise Reductin On, on some effects. It is easy to create your own effects and simple to use. The facory presets all suck though.
