Just got this , so I'm still tinkering with it.But, I gotta tell ya, this thing is AMAZING !Despite having some virtually useless presets, the customization available is astonishing.I've owned various Digitech pedalboards like the Rp-10, but this thing has rendered that nice unit unusable.One BIG difference is the way you adjust the presets. In older models, you had to labor through a quite confusing process to adjust them. With the GNX4, you simply push a button and dial it in. I took the #1 preset (Hybrid1) and basically modded it to sound like DimeBag's rig, and it sounds AWESOME. I have a little 'digitizing' going on; mostly due to the compressor, but that was to be expected.Enough about presets, let's get to the other nifty features :mp3 player, Drum machine and onboard 8-track recorder have all been tested and work quite well for what they are. I would suggest buying a 1GB CF card (I got one for $$). That'll hold 99 (limit) mp3's and about a dozen or so 8track stereo recorded songs. I could go on and on; but won't.NOTE: I hooked this up to my G4 MAC and it worked like a charm. I drug a few songs directly from iTunes into the mp3 folder of the CF card and played it back through my rig. This will come in handy using headphones late at night when I'm trying to be incognito.The learning curve is a little steep to use all it's feature set, and the software (PC/Mac) takes some getting used to;But all in all, this has got to be the COOLEST tool for a hobbyist or a PRO I have ever seen.The $$$ is a little high, but just go out and price a good foot controller, Drum machine and Digital 8-track recorder and see a cost about 3 times what this cost.If you're serious about your music, then this is the last product you may ever need.I seriously suggest to anyone looking at this unit to go to vendors site and research this unit.

I used a Fender Stratocaster and a Carvin amp while evaluating the GNx4. Don't buy this unit. I did and regret it! Here's the reasons why:A. This unit comes with 80 factory presets and 80 user presets. The 80 user presets are exact duplicates of the factory presets. The 80 factory presets can't be changed. of the 80 presets, only about 8 are not distorted. This means, if you want additional presets that are not distored, you have to progarm the unit. And the interface to do this is not user friendly. Which leads to the next itemB. To program requires one to enter the parameters (amp models, speaker models, reverb, etc) to set the preset up. The major problem here is getting the equalization (EQ) right. The problem here is that you can't here the effect of the control (center frequency and gain) while you're adjusting. You have to come all the way out of the program to hear the bass, treble, midrange and presence settings entered. Typically, it took me 4 to 5 tries to get the dry (straight tone on my guitar) to match the wet (tone from the GNx4) to match). If you don't get these tones to correspond, the tone of the istrument will change when you go to use the preselect. Not good when you're using it on stage.C. The last comment concerns volume levels on the factory and user presets. They are extremely loud. The levels are set at maximum from the manufacturer. This means none of the manufacturers presets can be used when performing. If you do, the change in volume is so loud you can't use it without turning down your amp. The user presets can be turned down but what a pain to have to lower 80 presets. It will take you hours to match the dry to wet volume levels.I can't recommend this unit to anyone.

Not Tough Enough

By Anonymous

from Undisclosed

I bought this pedal about 3-4 years ago and I was amazed by it. It had so many features and tones that I tought I would never buy another pedal... The truth is: I didn't anything about good tone and sound. I think it sounds alright if you have a decent amp, but not as good as a tube amp.The other problem is, it's not very tough. It's at the point where the wah pedal won't work most of the mp3/record buttons are broken. So i can't create new effects or new amp combinations.I think you should save your money and buy the new rp1000. This pedal might have been hi tech 4 or 5 years ago, but its not gonna cut ist now.

Great but could be sturdier

By Cap10quarterz

from Winchester, TN.

I owned this and while i was completely nuts over how much you could do with one unit, i was dissappointed at how cheap it was put together. Granted, it would have bumped up the cost, but I've a fan of pedals built like a tank. Plastics knobs and buttons tend to break (especially if you're running around on stage like a maniac, stomping on this thing). Needless to say, the knobs broke on me to the point all i could use was the "3","4", and "5" pedals. I had to use the wah pedal to turn on my distortion. So if you're careful- good buy. If you need military grade hardware- goodbye.

Dream Tool!

By hitrockit

from San Diego

Found a refurb deal here. Great savings and the condition was perfect. Let me tell you there is not much the pedal can't do. My band has played and gigged over 15 times and GNX4 has served me great! I went on a trip and took it with me. So much fun to have my mp3's, drum machine and bass emulator right here! Connected it up to a buds Jeep car stereo inputs and jammed. Ran a MK acoustic elect into it and doing the beach craze Buffet tunes was the attraction. Some guys were guitar players and never game much look at the GNX4. They want one now ;) Many ways and audio routing options. I play a wedge and a pa sys. Sounds excellent with my back up tracks. I'm going to expand the amps with the online discs from mfx. I bought 2 flash cards and have 150 songs of our sets to practice with. Tellin you, it don't get any better.

It is a Beast

By Anonymous

from Undisclosed

I got the GNX4 about 2 years ago and it still is in good shape. There is nothing this pedal can't do. And for the price it is a great deal. you could spend more money on buying stompboxes to equal the amount of options this baby has. 5/5 of course. I would highly recommend this to a friend.

Muy Excelente

By 8-Ball Jones

from Oklahoma City

This is probably the best investment I've ever made. I travel quite a bit and this workstation is IDEAL for mobile recording. Just hook up your headphones and you have an 8 track studio with hands free recording at your disposal. I recommend this to any guitarist that wants to record a full bands worth of music before rehearsal. CHECK IT OUT!

Not just any modeler

By Terry-fjAbO

from Oakdale, California

Jus like the title says. This box can do so many different things. It does them well. Having played live with it with a coffe shop trio, all those features come in handy. We jam thru a mid size PA. Sounds are great. Sometime we use the just the drum machine from midi songs we made. Other times we use comp file mp3 songs. Those can be put on a compact flash card. Holds 99 songs. Plenty for our work. I run a Takamine acoustic and a Super Strat thru it. Has a cool feature called pickup emulator. My Strat can sound almost like a Les Paul! At home just hook it up and play. You don't need a computer for that ;)My favorite part is the recorder is built in. None of the other Digitech line or compatition pedals have this option. One more gig and I'll buy the models online. I had some sent for some blues tones we needed. Samples were very nice. I hooked this up to two Event monitors at home. Sound from the GNX4 and what I recorded or play along with is amazing! There is other gear out there but none with this kind of capacity or tools to use. It's built pretty solid. Steel top and bottom, but not plastic like some other ones ;) I give this a huge thumbs up!!!!!!

Excellent bang for the buck!

By Robert F

from Tennessee

I recently got the GNX4 for our live gigs and I must say I absolutely love its versatility. I could not be happier. I play alot of 50's warm tones and rockabilly and along with the Line6 Spider III and the Gibson ES-33 this unit is unstoppable.

GNX4 (with GR20 & Godin) RULES!

By Rejyna

from One foot in Ohio, the other in California

Ask me a question

Been doing this pro since the mid-70's, this by far is the most valuable piece of gear I own now besides my axes. Took me a few months to learn the unit basics, and a few more months to learn how much more flexible it is using it with the laptop and supplied software. We have released fine sounding product using the GNX4, it is the furst Digitech gear in our studio, and because it RULES, we also got the Vocalist LivePro (which RULES too!) - Use this mainly for the Godin Freeway Synth Axe thru the GR20 into the GNX4 - what a way to create. Looked at all the other similar priced units out there - none even comes close for this price. This has made it easier for any of us to sit down for a few minutes and get a muse on - the best ideas come when you're on your way out the door or to sleep. This allows you to put multi-track wave AND midi files down in minutes. And buy the footswitch at the same time you buy this, it doubles the flexibility of the GNX4. The only folks who don't like this beauty are those who didn't read the manual more than once through - took me like 5 or 6 times through... Read the manual. Thanks Digitech!

has run its course

By Lizardneck

from boise idaho

Having had this unit since it's inseption 4 years ago, I have used and tweaked it in every way imaginable. I find myself using it mainly now for headphone practice and as a tuner only. For headphone practice it is a great unit and sounds really good for that. For live guitar sound however I feel it does NOT cut it and really doesn't produce a viable "true" guitar sound. I have used it with the supermodels which improved the sound alot but even those are dry and fake sounding. Not even close to the real thing. With the introduction of programmable tube amps with built in effects such as the Hughes and Kettner Switchblade(which I own) as well as the tried and true tube amps(have those too- 5150, Marshalls) that have been around for decades I find very little reason to use this unit for other than headphone practice now. It cannot come anywhere near the organic sound quality for guitar tone as a real tube amp does. GREAT headphone practice tool, but thats it.
