  • Go way beyond vintage with advanced COSM

  • Clean, intuitive user interface

Go way beyond vintage with advanced COSM

Sporting a next-gen COSM processor, the BOSS GT-100 opens you to new avenues of sonic expression. Re-creating precise details of vintage amps and their behavior, the GT-100 goes way beyond cloning them to give you vast new frontiers of undiscovered tones. Amp Customize lets you start with a classic amp then morph it into another dimension altogether, carving out totally new sonic territory.

Clean, intuitive user interface

BOSS has fitted the GT-100 with a highly effective, easy-to-operate dual-LCD/8-knob user interface that gives you quick access and very intuitive control. Perhaps best of all, there are no menus to navigate! Every parameter is always available for instant tweakage. Tone customization functionality has been improved as well. All your amps, patches, and overdrive settings can be created from scratch and/or customized with the user-friendly graphical Tone Grid.

Sculpt new tonal textures with the Accel pedal

The BOSS GT-100's Accel pedal puts considerable tone-shaping mojo right under your foot. Control multiple parameters at once, as well as time-variant effects such as Twist, Feedbacker, and S-BEND. Use the pedal to conjure creative combinations of parameters all interacting in real time! You might be getting the idea that (aside from staking claim to being a monster tone machine) the GT-100 is also boatloads of fun. And you'd be so right.

A/B Channel Divide function

The GT-100 sports another new feature: A/B Channel Divide. With it, you assign different amps and effects to each channel and divvy up the signal by dynamics and frequency. Each channel drives its own effects and amp settings. Assign creamy, liquid lead tones to the mid-to-high pitches, for instance, and gritty, cutting tones to your lower notes. With the BOSS GT-100, you can explore a vast universe of tonal possibilities.

BOSS GT-100 Amp Effects Processor Features:

  • Advanced COSM amps that model vintage amp tones and deliver never-before-heard tones

  • Dual-LCD for simple and intuitive operation with direct access to every parameter
  • Improved EZ Tone feature with graphical Tone Grid for constructing new patches
  • Amp Customize and OD/DS Customize let you easily create original amps and overdrive/distortion
  • Newly developed Accel pedal for simultaneous control of multiple parameters
Take your guitar tone to the limit with the BOSS GT-100 Amp Effects Processor!

Boss GT-100 Guitar multi-effects Pedal

Love this pedal and the versatility- can make it sound like just about anything! I did a lot of research and tested the gear at Sweetwater (they were super accommodating)! Anyway I watched tons of YouTube videos and reviews and was leaning towards the Line 6 Helix since I own a Line 6 Vetta II but $ - thought it was overkill for me. So I tried the Boss GT-100 hard to believe that you couldn't get the majority of your sounds using this pedal and the UI is super easy to use. Just go to the Boss site and download it right away and then you can use that app to start downloading custom tones from some great artists for FREE! I also wanted a great amp that I could use with my acoustic and my electric guitars and that would work with my GT-100. I settled in the ROLAND JC 40 which sounds awesome with my acoustic and my GT-100 sounds great through it when I just run the amp clean with no special effects.Hope this helps - best to all and Sweetwater rocks!

Just what I needed!

I play live twice a week to 400+, and over many years I have jockeyed between a tube amp and analog pedals to a Multi-Effects board and a Tech 21 Power Engine 60 poweramp. Never being able to hit the sweet spot at our venues because of Stage volume needing to be lower, so I would switch to Pod HD500 or Fender Mustang Floor to try and get more sustain and high gain, but never finding MY TONE. I will say that the Fender Mustang Floor by far has a better tone to my ears than any other Multi-Effects up until now. Enter the BOSS GT-100! This thing just works for me, and sounds as good into an amp as it does Direct to House. I am amazed, truly amazed at all this thing can do! If you are looking for tone with puff and sponginess from a multi-effects that is akin to tube amp, THIS IS IT! Bar-None. I enjoyed many of the factory presets, but this became my dream pedal after ordering patches from Glenn Delaune, and Jack Thamarrats presets on Boss Tone Central. Jacks tone is exactly what I like, and I was truly hoping mine would sound like his when I engaged the patches...IT WAS SPOT ON and I am in tonal and creative bliss! There is a reason its called a BOSS!

Very Good Product

Just got my new Boss GT-100 from Sweetwater.I think Boss has raised the bar with this new release.You get all the great Boss effects with some good Amp modeling. I myself will use the effects rather then the Amps within the unit. This is not to say they are bad, they are in fact rather good I just rather use them within my amps. Very easy to navigate and create your own sounds as well. Also a nice plus of being able to use it within my Daw. You can really get everything from over the top metal leads to even a sitar.The unit is very solid and ell made. There is nothing not to love about this unit, and I'm sure whatever you play you will find your tone.

WOW!

All the effects are really, really superb. One of the many cool things about this is that you can assign any of the built-in effects to any of the pedals. I'm not really sure why one of the other reviewers mistakenly thought the pedals aren't assignable because they are --> (see user manual pg. 17) The distortion and reverb effects are better than stand alone pedals that cost more than this. Boss really raised the bar when they made invented this amazing machine! :)

Incredible

The best peace of equipment that I have had in a long time had an ART SGX2000, and Then the Boss gt-10, Like the fact that I can Split different amp sims to left and right for a true Stereo setup, have only had it a couple months and as of yet have found no limits to it.
