Gnx 4 worth the money

By Superdave

from cedar rapids , ia.

The gnx 4 is a great board for what it is designed for.It is designed as a work station not to be run into an amp really as is.You do not really wnat to run this in front of your preamp if u have a tubee, instead run it into the efx return.Gnx is best through head phones for practice or into board direct. If u want to run into amp try bbe behind it or turn off spk sim and turn down tone controls and presence or will get very fuzzy. Great unit for what it was designed for.

The most awesome board

By Roadie dad

from Miami, Fl.

2 years ago I researched multi effects boards and decided hands down on the gnx4, I bought it for my son. He loves it, it is part of his sound; a PRS, fender tube and his gnx4. It does all the things they claim, it is awesome.. so I'm not going to sit here and rewrite all the great features. Just say that this board is still going strong after 2 years,(constant use) the power supply cord broke from years of winding it up and that was easy to replace. But it made me realize how valuable this is to him and if got lost or stolen he would be in trouble, so I bought another one. I'm not rich, if I were I would have bought 10. This board is going to be a part of his sound for a long time. I bought three extra things, the foot control, gig bag and the mfxsupermodels..

The Perfect Practice Partner

By Steve

from North Bend Wa.

I started out by researching everything i could to find what was best for my needs as a part time guitar teacher. What I had learned is that the GNX4 had the most to offer as a teacher and definately the best bang for the buck. It allows you to create seemless jam loops on the fly hands free as well as offering up an endless supply of tones to create and effects to play with, and let us not forget a really decent midi drum machine and a digital 8 track recorder. You do need to spend the time to learn to use this machine, it's not to difficult but the extra effort is well worth it. A tip for those of you buying or currently using this machine is that you want to run the "output" to your amps "effects return" and your guitar directly into the unit it's self for the best sound quality. This simple setup keeps the two preamps from clashing and causing tons of noise and poor tone. For the best sound possible a small PA setup is best overall, this allows the true amp modeling to shine through, the reasoning behind this is that a PA has a flat EQ signal and as we all know amps each have their own sounds and is what sets each company apart. So if your looking for the ultimate practice tool to keep you sharp and give you some toys to play with too, look no further! Also there is a wealth of information on the GNX4 at guitarworkstation.com. Thank you for your time and i hope this helped some of you looking for a great inexpensive practice tool with tons to offer!

I'm still building new patches for this thing...

By Stephen E.

from Clinton, MD

I got this as a Christmas gift when it first came out and it's still a staple in my home studio. It says 80 factory 80 user but if you get a Compact Flash card you get an additional 80 patches! It has way more i/o options than with similar products, I run my rig in stereo so it's a huge plus. 2 to a stereo track in pro tools the other 2 to my guitar amps that's a ton of tonal variety in one take.

Loads of features

By Snapper

from Micigan, USA

Got this the other week. Even though I'm a beginner guitarist, I really find the drum machine portion of this device very helpful. I have never really gotten used to a metronome yet. What I like about this device is the flexibility it provides since it includes so many functions. I'm not anywhere near scratching the surface of what it can do, obviously, but over time, I think this thing will keep me from spending money on stomp boxes that are not needed.

I thought other pedal effects were good. Have a Xt Live but I wanted one with more features. This has the goods and then some. Easy to use. Has worked great with Sonar Producer. My tracks are nice and clean and have NO FIZZZZZY to fuss with. It's about time one of these pedals go that right. Since I bought it 3 months ago I have done 4-5 gigs. No failures no problems. I am buying the sup-model upgrades for new amps to add. So many said they rock. That can add to my tone set and make me love this more. You can't go wrong with this. First I wanted a Boss 8 track and then maybe a Gt-8 or 10. After finding out the GNX4 can be those and an mp3 player and drum player machine I ordered. Glad I did. This is awesome!

Incredible machine

By Relivingmyyouth

from Westchester Cty, NY

I got this a couple of days ago after reading all about it. It is really amazing, the tones that I am getting. The multi track recording is really easy to use, and works well. I haven't had a chance to work with it on the computer yet, but thats next. NOTE: READ THE MANUAL, it will make everything much easier.

Perfect in just about every way

By SamsDaddy

from CO

I have owned the GNX4 for 6 months now and use it every day. There is not a more versatile or valuable tool on the market for a guitar player. First of all, you have all of the amp/cabinet models. Purchasing all of these amps separately would cost THOUSANDS of dollars. I compared the Vox AC30 model to an actual VOX AC 30 that I was demoing and the tone is nearly identical. Secondly, there is just about every effect you need built right into this baby - tons of different overdrive pedals (TubeScreamer, etc.), chorus, flanger, phaser, and on and on. Third, you have the built-in 8 track recorder. Have an idea for a nice riff? Stomp the record pedal, lay it down, and you're done. It will automatically loop your recording as well (just like the JamMan looper). One feature that is not often mentioned about the GNX4 is all of the output/inputs offered. 1/4", XLR, USB to go to PC - this replaces your mixer! The previous reviewer got one thing wrong though. This thing is not a 6 - it rates 1000 on my scale based on what it would cost you to replicate everything the GNX4 does with individual components. Buy yourself a PA or other full-range stereo system to take full advantage of the amp modeling and stereo effects. You will NOT be disappointed with the GNX4. It is worth every penny. Go buy it now.

5 max? It's a 6

By MtljmzJim

from Fort Worth TX

This thing rules! Look at the list if you are wondering. I seriosly was checking out pedals at GC and some wanted me to go to other named products. I had the wrong guy for one. I said what I needed and was looking for, and the sales guitar guru said GNX4 my friend! ya See, I was looking at a BR recorder and a POD Xt. I needed an all-in-one. He hooked me up. Took it home and started playing. Right away I loved the tone, the feel. I grabbed my flash card from my camera and started recording. Drum tracks for a minute. Then since the salesmen showed me bass and acoustic patches I laid those down. Easy as pie! Record a part I didn't like. UNDO!! Woo hoo! new part, guitar tracks and a solo. Finishimo! First test perfect. Then I tested the flex-bility of the matrix to see what I can change easy. It was! Ok, it has USb. That's for the PC editor and recording software. Plus I found out I can make drum patterns and songs there. Digitech site links to Workstation and tutorial galore. After a couple hrs I was running smooth. Hit the Forum, say Hi, and read. Now the talk of model kits (reviews below duh). I like metal. Hard Rock collection 3 days later!! That had more learning videos! Had some Q's pc stuff for pc drivers. Call Digitech and they fixed it. Xperiences like this are few and far between. My GNX4 is 4 moz new and I love it like my custom geetarz! I am in metal mania and can play anytime day or night. It's no MB RECTO but for writ'n tunes and jamm'n trax, it's great and sounds like I needed it to!
