Awesome so far!!!
Style: Effects Processor
TL;DR- An amazing multi fx pedal that rivals many competing flagship processors in build and audio quality with ease of use. The GX-100 seems like a steal at this price point. It sounds amazing either running through an FRFR speaker or studio monitors. The tones are versatile and can cover a huge range of genres (yes, it chugs & djents). One con I noticed people saying is that some amps are not really modeled after anything. To me, this is a pro. I feel it allows for better creativity in creating a tone, as I dont have to waste time referencing. I dont have to worry about it sounding like a 5150, I just need it to sound good, bottom line. The quality of amps make up for the humble 23 available (3 of them are bass amps). Aside from the tonal quality, you can also run dual amps for more unique soundcrafting. The amount of effects available are quite staggering. The screen will only show you a handful of blocks, but most blocks have a "sub type" of each effect. For example the OD block has the OD-1, OD-2, Blues OD, CENT-OD, ect. Some say that the distortions sounds fuzzy, but as with anything that isnt $2000, youre gonna have to work for your tone, theres so many options to shape your amps and effects. I also recommend loading you OD or Distortion before the amp. I've seen this gets rid of that thin fuzziness and sounds more modern. If you're tech savy, the BOSS Tone Studio will help a lot in shaping these tones. You can connect via USB and go nuts on your tone shaping without messing with the screen. You can also use this baby as a recording interface. Im a bit new to the audio engineering side of things, but this thing is great for recording, it sounds awesome, and the latency is super low. The only bad thing I can say about that is that your effect cannot be changed post recording unlike with plug ins (ie. Neural DSP). Again im new to this recording stuff so there might be a way that I dont know about. The touchscreen is really cool. The response is lacking a bit but the construction is top notch, doesnt feel like ill crack it anytime soon. Speaking of construction, as others who reviewed before me, this thing is built like a TANK. Everything feels solid, the buttons are plenty and the grip on the the expression pedal is similar to the grip on skateboard. One last thing ill add is the ease of use. All processors have steep learning curves when it come to figuring out the buttons, sounds, and chain building. The GX-100 is one of the easier ones to figure out. Still a bit of work needed but a lot less than say... an axe fx or a Cortex. ... show more

Best unit I've tried so far for its price. Easy to use if you have had other Boss MFX before.
Style: Effects Processor
Take your time to read, I hope to clarify some doubts you may have while thinking about buying this unit but long story short: Just do it (it worth every penny), and I'm going to tell you why. If you are looking for something that allows you to create your own sound and manipulate almost every aspect of it, literally, get this unit. Some people could feel overwhelmed with the settings at first, others will say its distortion or drive sounds doesn't sound well but let me tell you: they can sound really great, but it will require some time and patience until you get your ears used to how this unit sounds and learning to identify what to change/alter in every single thing you put in the effects chain. Try every knob, every setting, take a little break to give your ears some rest and sit back, our ears adapt fast to any simple variation to the sound. Not all the knobs will act exactly the same way in all amps, take your time and experiment with that too. I'm still working with the stock IRs; they can sound great enough to get almost everything and sometimes using the other included cabs rather than the amp original one could match even better (for my personal taste). Don't try custom IRs before you get a very good sound with everything that is included already, you might see yourself losing lots of time (and money) and still sounding like ars. otherwise. I have almost 20 years of experience dealing with some simple/complex units and some moderate analog pedalboards. Take your time, experiment, embrace some frustration at first until you train your ears to recognize what's affecting your sound and how can you get the sound you want. Learning to manipulate the unit is the easiest part, and even easier if you have used another Boss MFX before (I had the GT-10 6 years ago), but learning how to use it will take some time, be patient and try to find a good and almost as flat as possible reference to hear it (if you're setting it for line or direct) to be accurate. As I read some user comment in a YT video, use your ears... don't let names or references fool you and tie you. Remember that using patches created by others won't work even having the same equipment or guitar as everyone plays different. Some factory presets are ok but not as good to use them in a real situation, learn from them, see how they work and if you want, start creating from there although it's much better if you start from zero and just try some amps first. Also, if you think about flexibility, this can be a monster... whether you use it in manual mode or in memory mode you will be able to remap every single switch with even multiple functions at once. If something plug and play is what you're looking for, look for somewhere else... but if you're like me and you want to have the maximum control of your unit, get this thing. ... show more

Welcome to the 21st Century..

Tired of that old, nasty, dirty pedalboard with all of those stupid chords and power strips? Constantly fiddling with wires and pedal positions? Take a chance on this product. My old pedal board is obsolete. Can literally produce any sound you want with the right patience and calibration. This is the future. I just take this to gigs now. Superior quality. I've been using it for over a year now. No issues with electronics, is metal framing so can take a beating. This board has changed my life. Welcome to the future of guitar, friend. ... show more

Excellent value and versatility in a pro-tier package.
Style: Effects Processor
Astonishing flexibility, good sound quality, and best-in-class low latency (invisible, <2 ms) which is why I went with this over competitors like NeuralDSP NanoCortex. Seamless DAW integration, high quality effects, too many useful features to name. With this, a DAW on a laptop, a guitar + cable, and wired monitor headphones, you can lay down an entire album silently. Fantastic! Only con: it takes a lot of fiddling to get decent sound quality from distortion and onboard amp sims, but if you have an amp sim pedal you already like just put it in the send/return loop and you're done. Also works great as a multi FX kit if you want to mic an amp the old fashioned way, and for the cost of 4-5 FX pedals what are you still doing reading this! Very hard to beat at this price point and form factor, unless you just need to be in the NeuralDSP crowd. ... show more

Excellent quality at a great price!
Style: Effects Processor
The build quality is really good and it is easy to use. There are a decent number of amps that sound great and lots of special effects, very customizable, you can run two amps simultaneously/ in parallel and even load your own custom IRs using the Boss software. I totally recommend it.

Do some research, you're in for a lot of aggravation if its not designed for your gear.
Style: Effects Processor
Boss dropped the ball on this one in several ways.. No printed manual... the pdf manual doesn't cover most of the important stuff. It's more like "for dummies" book than actual instructions. Boss decided to leave us real amp guys out to dry and cater to the bedroom players on youtube. There is no info on using this thing for guys who play live and loud. If you plan to use the 4 cable method through a powerful tube amp, like a Marshall, you will be very disappointed. It makes every tube amp I own sound like boiled crap! The individual effects work well alone but don't play nice together. You have to download the editor and try to dial it in on a computer, you cant save or load individual patches 1 at a time ,you have to save or load it all which takes time... If I knew about the updates, the annoying editor and that I'd have to spend hours looking for, and not finding, the info that should have been in a printed manual, I wouldn't have wasted my money.. This unit is fine If you want that sterile amp modeler sound and like playing with computers or if you want to make a $2500 tube amp sound like mud. I'm putting it on the shelf after I make a video about it for the tube amp forums... I highly doubt I will ever buy another product from Boss or Roland ... show more

Dang…
Style: Effects Processor
This thing def lives up to the hype. Have it through a 6505 combo with a V30. The amp isn’t known for its cleans but the boss improves it substantially. I don’t stay in the clean channel very much however, mostly high gain with a 7 string with dimarzio titans. The noise gate is amazing, just as good as the boss ns and you can put one through the effects loop as well as in front of the amp. It’s nice to be able to switch channels on the amp with the boss. I can switch patches to where it changes to the clean channel On the 6504 and then use a high gain amp and IR through it for different heavy tones, then switch back to using the 6505 preamp with just effects on the boss. I could go on and on and on about all the stuff you can do. You can customize this thing to death it’s unreal. If you can imagine it, it can do it. I don’t use the looper much so can’t comment there. Even the built in tuner you can customize between 6 and 7 strings to literally any tuning you want. Yes it’s $600 but if this thing was $900 it would still be worth it. It’s the only pedal I’ll ever need and completely eliminated my clustered pedal board and sounds just as good I think better than individual pedals. A bold statement I know but boss absolutely nailed it with this thing. I spent hours watching videos comparing it to the helix hx, mooer, the pod go, and some others and the gx-100 is just the way to go. Love the touch screen, super easy to use, and comes with pc software if that’s your thing. Can even use it as an audio interface to record with. Or just grab some headphones and jam out on the couch without getting your neighbors involved. The stereo effects are down right addictive when jamming out on headphones. I have yet to find one complaint with this thing and guitar and amp aside it’s the single best thing I’ve ever bought for playing music. ... show more
