Shift Your Tone Into High Gear with Next-Gen Amp Modeling

The BOSS GT-100 Amp Effects Processor blows past its predecessor with next-gen amp modeling that gives you incredible vintage guitar amps as well as new COSM tones and effects to help you blaze new sonic frontiers. The GT-100's user interface, with its easy-to-see dual LCDs, gives you instant access to beastly processing power, while the popular EZ Tone feature has been freshly juiced with powerful customization options. USB lets you inject this tone potion straight into your DAW. Want to shift your guitar sound into high gear? Your pedal has arrived: the BOSS GT-100.

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 tweaking. 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

Best Guitar Multi Pedal

Too much to tell.1. Look cool, easy to see on dark stage. Quick learning curve. I can show someone new to play very quick on this.2. Presets are nice but BOSS TONE STUDIO software is a MUST HAVE. Down load some cool patches without messing with the settings.3. Go MANUAL if you're inclined to do so.4. Smooth to gritty sounds. Conclusion: If you truly don't like this then go ahead and buy HELIX.

This is not your father's GT-10

First impression - Wow! The sound is much more organic and controllable. The interface is smoother as well. I 've played it through tube and SS amps and through a P/A. It sounds great. A huge feature on the current version is USB double tracking as a recording tool. You have to download a driver but once you set it up it records wet and dry simultaneously. You can go back and change or blend fx without having to recut the track. I like this product.

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.

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! :)

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.
