Boss GT-100 Amp Effects Processor
My trusty pedal! I don t want to sell it because it is just such an awesome a versatile. You can turn off the amp modelers and have a whole truckload of effects at your heels, and they are all very well designed. I found this pedal freed me from all the knob turning I was doing band jams and let me just focus on playing the guitar. Also, if you re just starting out, this gives you a great idea of what pedals you may consider for a more comprehensive board as you grow as a player! The gig bag is great, the pedal works flawlessly- this is a stunningly good deal!

For someone, a novice, that has had it for only two weeks, that should tell you how easy this unit is to use.

After using an HD500x for a couple of years, I finally bought the unit that I had wanted in the first place, but been talked out of by a (justifiably) enthusiastic Line 6 fan in my circle of musical collaborators.The choice between that and the GT-100 is largely a matter of subjective taste. Neither is , of course, the very latest technology , yet both can yield impressive results. I have to say, though, that the Boss unit is immediately more to my liking.I will continue to use the Line 6 unit, of course, which is claimed by fans to model branded amps and effects more accurately, and gives very fine control over every sound parameter I can imagine.However, to my ears (playing through a very basic Fender Blues Jr.) the Boss sounds more open and natural.

It has many more preset patches that I would personally be comfortable using out-of-the-box. And for when I do need to edit a patch, I find the interface clearer and more intuitive.

I was a Digitech RP500 user and to me that multi was so easy to set up. I sold that RP and switched to Boss GT10 to see what's the fuzz about it. I was not impressed at all. Then I met a guitarist online and he was selling his Boss GT100. We both agreed on a trade plus cash deal and so I got the GT100. As soon as I bring it home and tested, i can little agree the sound of the GT100 was warm than the GT10. But as days and months go by and try using I noticed a typical "high mid ish" of the GT100 like the Boss GT10. By the way, I'm using the GT100 directly plugged to my amp's input. Just few days ago I was looking for a reference info how to reset the GT100's preset of the few patches that I modified. I incidentally got into a forum about GT100 and it was mentioned ...

I incidentally got into a forum about GT100 and it was mentioned there about adjusting the input level of the GT100 global setting. They said if you have a humbucking pickup the input level should -7db below. But if you have a weak single coil pickups then used -7db up. I'm using a Fender Mexico black top that I put an SD TB4 on the bridge and 2 Dimarzio 61 on neck and middle. To my suprise the -7db is already hot yet controlled sound no more clippy sound. But the -6db is what I really like. All the effect from distortions to modulations, reverbs now sound warm and less digital to somewhat organic.That's how my has perceived. Also take note of the high mid Q on the global setting. Default is 800 Hz. I backed it down to 500 Hz to lessen the high mids. Try it and thank those people who share this info on the web.

If youve use a similar product (I moved up from the previous GT8) youll know that you cant have massive functionality without a bit of a learning curve. Its for that reason Id put off upgrading to the GT-100 but after only a few hours Im really glad I did. This is a great system. You can create great sounds by just finding a patch you like and editing it and saving it as a user patch. But it is astonishingly easy to create them from scratch. Using the EZ Tones function you will be able to find something that suits the kind of music that you want to play, and then make minor edits to it. After a little bit of fiddling around you will realise that visually scanning through the effects chain, and turning on/off and tweaking patches makes it very simple to edit and save ...

After a little bit of fiddling around you will realise that visually scanning through the effects chain, and turning on/off and tweaking patches makes it very simple to edit and save the sounds you want. One small criticism, as they seem to have dropped the solo function (you used to be able to step on a patch a second time I hear the louder version). You can still using this using the CTL pedal however. I have not used it to record using USB interface yet, and I do not know how it compares to them much more expensive This is a top piece of kit so do not hesitate. I have not used it to record using USB interface yet, and I do not know how it compares to them much more expensive GT1000 but.
I have had Boss and Line 6 devices and really like the sound of Boss more. This works beautifully as an audio interface for my DAW. I like the send & return and the overall flexibility in configuration options. I tend to programme from the laptop but with the two screens and many knobs, it's not too stressful to tweak directly. I like the build quality and the appearance. But all of that would be irrelevant if it didn't sound right and I love the sound. I use it for bass (active and passive) as well as guitar and I find it's great for both. To my ears, it's more natural sounding than the, admittedly older model, Line 6 I had. If this were to be lost, stolen or destroyed I would definitely get another.
Perfect condition and included the OEM power supply and computer cable. I had one of these previously but sold it. Been playing with some others and needed some effects to play through a bigger amp. This fits the bill nicely and the included road runner bag is much appreciated! Good deal.
I have been a customer of Andertons for several years. I am a big fan of this store because the service offered is consistently professional, reliable, respectful and polite. The products are always of the highest quality and I never feel rushed whenever I try them out. This makes me feel valued and relaxed as a customer. As a result, I feel that I am afforded the time to spend good quality time with the products which in turn helps me to decide whether or not to proceed to the purchase stage. I also feel that I get a much better understanding of the product before I leave the store. All that I can say is keep up the great work!

If you don't care to read this long review here is the summary: Please ignore my bad review from 2012, I think the unit I had was defective and had gain or digital issues. I bought another one and it sounds much better. I bought one of these in 2012 and afterwards returned it and wrote a bad review in 2012. I can't go in and edit the old review, so I am posting this to set the record straight. I thought that the amp modeling was terrible since the unit I had sounded so bad. I tried for days to get a decent sound and eventually returned the unit and got a POD HD500 which I still own. Recently I had a chance to get one of these at a large discount and decided to give it another try. I figured that as bad as the amp modeling was I would just bypass it and use the ...

I bought another one and it sounds much better. I bought one of these in 2012 and afterwards returned it and wrote a bad review in 2012. I can't go in and edit the old review, so I am posting this to set the record straight. I thought that the amp modeling was terrible since the unit I had sounded so bad. I tried for days to get a decent sound and eventually returned the unit and got a POD HD500 which I still own. Recently I had a chance to get one of these at a large discount and decided to give it another try. I figured that as bad as the amp modeling was I would just bypass it and use the 4-cable method to use my amps tone. I'm not sure if it is the new firmware in these (ver 2.03) or if the unit I originally bought was defective, but this one sounds much better. While the amp models don't quite respond as accurately as the HD500, they sound good. They don't have as much of the thin digital sound as the pod, they are much fuller. The unit overall sounds warmer than the HD500, less noisy and some of the advanced effects like pitch/harmony and slicer are better than the POD. One major difference between the HD500 and the GT-100: The basic tone of the unit when amp modeling is turned off. This is the most important thing to note because I think it will affect your opinion when you demo the unit. When I turn off the amp modeling on both units and set the bass/treb to flat, the boss has a very neutral flat sound like a JC-120. When I do the same with the HD-500, it still sounds scooped like an old fender amp with the bright switch on. This might explain why the pod sounds more thin and digital than the Boss. It also makes it have the illusion of having better sound clarity than the BOSS. After figuring this out and tweaking extensively I can get much better clean tones from the GT-100. It also makes fret buzz much louder on the HD500 than the GT-100. I've been using it for a few weeks now side-by-side with my HD500, and I see good and bad in both of them. I will probably be using the GT-100 as my primary unit because the most important thing is the sound quality and it is better with the BOSS than the POD. The HD500 has a distant sound, like you are listening to a pre recorded sound rather than live, which you might not mind if all you do is record with it, but for live it just makes it get lost in the background when playing with others. I think all digital units do this to a certain point but it is definitely worse with the HD500 than the GT-100. One last thing: The software with the Line 6 unit is much better than the Boss. With my Macbook pro (8gb ram and fast solid-state drive) the Boss Tone studio software has a lot of lag and wait time.
This unit is just incredible. I've been playing since the early 70's and with all the equipment that I've owned I really think the GT100 has possibly impressed me more than anything I've bought! There's some wonderful preset sounds in this tone monster and it's easy to edit the one's that you like. If you're already proficient at programming pedals then this one will be a dream for you to manipulate. This isn't my first multi effects pedal but I don't enjoy programming and this is by far the easiest to program of the one's I've owned. I can't say enough about the sound of this thing. It has every tone that you could ever need. It's extremely quiet too. I'm definitely glad that I made this purchase. I can see a lasting relationship building!
This effects processor is great. It can give you any sound you like, and you have a billion different ways to use it.However, if you should decide to plug this thing into an amp, do not plug into the input. Make sure your amp has an effects loop. Of course, these pedals are not made with true bypass because they are not designed to be bypassed, and plugging something like say an acoustic guitar into the input on the pedal and then into the amp would be terrible.That being said, if you do not have an effects loop, you can use your clean channel if it's nice and clear when you noon the eq on it. Or if you can get your hands on some Orange (or other) amps with Natural channels, clean with no eq, that would be even better.Or go direct, that's always the best way ...
