Meet the new BOSS effects flagship, the BOSS GT-100. The GT-100 Amp/Effects Processor boasts next-generation amp modeling that re-creates vintage amps and provides new COSM tones that soar into the future with the dynamics, tone and feel you'd expect from a boutique unit. User interface is improved by a dual-LCD system, while EZ Tone has been enhanced with newly designed Amp Customize and OD/DS Customize features. The GT-100 is a powerhouse processor that spans from classic to futuristic in a friendly, rugged and roadworthy unit.

Advanced COSM Amps: beyond vintage
With its next-generation COSM processor, the BOSS GT-100 offers all-new sonic capabilities. Recreating the meticulous details of vintage amps and how they behave, the GT-100 excels in not only cloning classic amps, but provides a new world of unimagined tones as well. The Amp Customize function lets you mutate classic amps beyond reality.

Easy to use
The GT-100's unique dual-LCD and eight-knob user interface provides fast access and intuitive control. There are no menus to navigate. The tone-customizing functionality has been improved as well. All patches, amps, and overdrive/distortions can be created from scratch or customized with the graphical Tone Grid.

New A/B Channel Divide
Another new feature onboard the GT-100 Amp Effects Processor is the versatile A/B Channel Divide. Assign different amps and effects to each channel, divide the signal by dynamics and frequency, with each channel capable of driving its own effects and amps settings. Assign smooth, mild lead tones to the mid-to-high pitches, for example, and heavy, cutting tones to the lower notes.

New tonal possibilities with the Accel pedal
A new dimension of expression is available with the Accel pedal, which enables control of multiple parameters simultaneously, as well as time-variant effects such as Feedbacker, S-Bend and Twist. Experiment with creative combinations of parameters, interacting in real time with the pedal.

Features
  • Advanced COSM amps that model vintage amp tones and delivers never-before-heard tones
  • Improved EZ Tone with graphical Tone Grid for constructing new patches
  • AMP Customize and OD/DS Customize lets you easily create original amps and overdrive/distortion by customizing their behavior
  • Newly developed ACCEL pedal for simultaneous control of multiple parameters
  • 2 LCD displays (132 x 64 dots, backlit LCD)

Like most, I have had ton of different setups over my years of playing. I have always wanted a nice, budget friendly multi-effects unit that integrates with my amp - not to replace it. The GT-100 works beautifully in this regard (and also surprised me at how well it could replace my amp, too!).

For me, the best thing about this is that I can easily take the GT, my guitar, and my amp (or any amp with a decent clean channel) and happily have a jam or play a gig with minimal fuss. I don't even need to setup a bunch of patches - I just setup a couple patches as different 'pedalboard' layouts and use the unit in Manual Mode. The global EQ can compensate for any difference between amps/rooms and can be quickly adjusted.

The icing for me was the fact that the amp sims and overdrives sound REALLY good and are very useable with an actual amp. I could never get the HD500X to sound near as good as the GT does with all of my amps (using the 4CM). The HD500X might be great for going direct or recording, but if you want to use a multi-effects with an actual amp (in my case, a Blackstar HT-40 or Crate VFX5112 or VFX5212), the GT-100 is the choice - hands down.

Likes:
- Can control my amp channels from the unit (and save the amp setting in patches)
- OD and amp simulations sound better to me than the HD500X when using them with in the 4CM - I feel they are WAY more useable with an actual amp
- Effects are standard BOSS quality re: excellent
- Very easy to use and make quick adjustments
- Super flexible footswitch assignments - can have one footswitch control multiple parameter changes across all effects and a can freely assign what each footswitch does (in Manual Mode)
- Power button! (are you kidding me Line 6...)
- Easy to read and useful display
- Great polyphonic tuner with the v2.0 update

No Likes:
- Effect blocks can be placed anywhere you want, but there are dedicated effects blocks for Comp, OD, Chorus, Delay, Reverb that can't be changed, leaving you with only two available blocks for "other" effects (HD500X will let you put any effect in any of the 8 available blocks - but you can easily run out of DSP depending on what effects are used)
- I like 3PDT footswitches, but understand why BOSS used this type of footswitch
- Would like some sort of physical feedback when clicking on the expression pedal
-

No opinion:
- Looper isn't as nice as the HD500X, but is still very usable for a multi-effects unit (if you are really into looping, you need a dedicated looper anyway)
- No XLR outs (I don't & won't ever go direct)
- No Stereo FX send/return (don't use stereo effects and if I did the GT would be handling them anyhow)
- Have no clue how it compares to the HD500X for recording - don't use either of them for that purpose

I really wanted to like this unit. I still really want to like it. At the end of the day, it is so close to being the device I really wanted to own, but unfortunately, after using it for 3 weeks, I decided it just wasn't cutting the mustard. Let me explain.

I play a mix of styles, and I play in a mix of bands. In some bands, I play acoustic, and in some bands I play electric. I really wanted a pedal board that could in some ways, complement both. Unfortunately, this unit is rubbish when combined with my acoustic guitars, and the reason is that there is no true bypass. That means, that there is no way to get an untouched, virgin sound out of your guitar when you are plugged into this thing. My acoustic plugged into my Fishman loudbox is a thing of beauty, and unfortunately, no matter how I tried, I could not get close to that crystal clear, poignant, yet rich tone that I get just running direct into the amp through the GT-100. No matter what you do, the tone is altered, and there is no way around that. The lack of a true bypass is a completely stupid oversight and is pretty inexcusable. Moving on..

I did some nice recordings with this thing while I had it. It can, when you fuss with it, really produce some good quality tones. I enjoyed the software that came with it, and found that it was easy to work with, well thought out, and again, mighty close to exactly what I was looking for. I can't knock this unit on this front. Customizing tones with this unit when it is connected to computer via the Tone studio, is a great time. I was able to learn it quickly, and I was able to get some great sounds out of it.

Still, the bulk of this unit is designed for the true Hard Rock and Metal guitarists out there. You know, the ones you always see thrashing away every time you walk into Guitar Center. If you are one of these people, you are pretty much going to love this unit. It was designed for your after all. If you are like me, and you like to play mostly clean guitar, but are in search of new tones to add to your bag of tricks, fatten your sound slightly here and there, add some delay, some envelope filter, some phase, some light sustain when the moment calls.. Then this unit can do that, but only about 10% of it was designed for you. And ok, that is also fine, because even the 10% that you get, is still a fun time. The effects are quality, and the unit is easy to use. You can spend an afternoon perfecting that sound you are after, and in some cases, you can come super close to achieving it... Maybe if there was one more soft compression unit, or clean tube pre-amp model included, but alas.. Plus, there is no clean bypass, so... moving on..

Ok, I was also encouraged that there was a looper bundled into this thing. I do a bit of looping, and used to own the Boss RC20xl back before it got stolen. I was excited to get the ability to loop back along with a bunch of other tricks, in one amazing pedal. But, you are limited to just 35 seconds. It might even be less than that. Seriously?? This is 2014, and this unit costs like half a grand. For that kind of dough, and the fact that there is an entire pedal on this device dedicated to the looper, there should have been far more function here. It is almost as though Roland added this feature as an after thought, or just because they knew it would look good on paper, but they did so in a very limited way, so those who are still serious about looping, will have to go out and buy a dedicated unit, preferably theirs. If you are going to dedicate an entire pedal on this 6 pedal unit to the looper, at least give us like 2 minutes of dedicated looping capability. Minimum!! Too often, I found myself trying to lay down a base rhythm track, only to get cut off before it was completed, and this was just friggin stupid! No excuse for this really! Why not just create the unit everyone wants, and sell the heck out of it? Why intentionally limit your device and your customers? Moving on.

Over all, I think this unit is as good as anything I am aware of that is out there in one device. If the right unit were created, which this could easily have been, I'd be up for buying it in a heart beat. As it was, I sadly returned this unit after owning it for 3 weeks, even though a big part of me did not want to. I know the unit of my dreams, does not exist at this time, and this is the closest thing to it. Still, I just could not justify throwing down that kind of dough for something that was so glaringly intentionally limited. I'd love to have a cup of Joe with the folks that designed this thing some day, so I could really give them a piece of my mind...

    Comments about Boss GT-100 Guitar Multi-Effects Pedal:

    Finally, I was able to test the GT100 on live gig last Saturday Nov 19th, and all I can say is WOW! Clean tone was warm, round but retains edginess with the right twang on my Dimarzio singles. The amp used was Kustom Tube Amp. It sounds airy with slight Chorus (like Dan Huff's chorus on rhythm). The Fat DS, and other distortions sounded so good. There was a slight to no digital sound at all. My lead tones sing. Other modulation like phaser sounds luscious. I'm using Fender Mexico Strat with Dimarzio Area 61 and Seymour JB TB4 on bridge with 250K pots. Even at 250k pots I still turned down my tone knob. On the global setting I tried the -8db on the input level, the mid Q is set to 315Hz. I also tried it on my Sterling JP60 and it sounded good.

    Now I'm thinking of getting another GT100 as backup. Sounds sweet and it sings. Not brittle as my previous Line6 HD500 that I sold immediately in less than a month few years back.

      Comments about Boss GT-100 Guitar Multi-Effects Pedal:

      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 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.

            Comments about Boss GT-100 Guitar Multi-Effects Pedal:

            Fantastic processor, especially given the cost. For what you would spend on four stomp boxes you get a processor that does far more than a huge custom pedal board. For those playing covers it has everything covered(pun intended). Toss the 100 pound amp stack, the giant pedal board, the twenty patch cables, the noise, and have fun. For original material, craft your own sound. I haven't bought a processor for twenty years because until now I thought that they sounded too "artificial", and couldn't see spending thousands for the rack mounted darling of the industry. Sure, it sounds good but so does the GT-100, especially if you have the ear to tweak it. Not to mention for all it can do, it's relatively easy to navigate and use. Can't speak to reliability as I just got it but Boss products historically have had stellar reliability ratings. The only outboard gear that may survive receipt of the GT-100 is an 1176 style compressor that cost more than the GT-100...but hey...let's be reasonable.

            A little about my equipment:

            My intent:
            I wanted to have a GOOD sounding alternative for gigs instead of taking my expensive equipment all over.
            I wanted to run from guitar to pedal to mixer into PA system.
            This pedal board is NOT good sounding like the analog equipment.

            It is fine for garage band stuff. But I would NEVER take it on stage. It sounds like it is all cheap digital stuff. no clear sounds anywhere. hissing and bad fuzz sounds...

            I put it through a DI box too. same result.

                If you're at all familiar with Boss's (Roland) COSM amp modeling then you already know what you're getting. If you're not... you probably need to hear this!! Don't be intimidated by this baby. The learning curve isn't steep and the payoff is huge. I can't even begin to list everything here. Google Boss GT 100 Videos and check some of them out.

                  I use it with an AC15 and it sounds great. I haven't had it very long but so far I'm very pleased. I going to run my acoustic through it and check out some of the presets. From what I've heard so far it appears to be better suited for Rock or Metal but I'm sure I'll be able to tweak it and get what I need.
