A modern "GT" approach: BOSS AIRD technology in a pedalboard-friendly format
The GX-100 carries the DNA of BOSS performance-oriented processors: modeling designed to preserve the feel under the fingers, consistent dynamic response, and easy integration into very different rigs. The AIRD technology doesn't just mimic an EQ curve; it aims to reproduce the behavior of an amp in a real chain (attack, natural compression, interaction with effects). The result: a multi-effects unit that adjusts quickly but retains real depth when you want to dive into details (IR, parallel routings, dual amp, etc.).
For whom, for which styles, and in what contexts?
The Boss GX-100 targets musicians seeking a compact, robust, and versatile solution: from beginner guitarists looking for ready-to-play sounds to seasoned players building a preset per song with scene changes and assignments. In live settings, the footswitches and "Manual" mode allow you to regain the spirit of a traditional pedalboard (activating/deactivating blocks like pedals). In studio, it becomes a practical partner for USB recording, headphone work, and crafting reproducible tones.
Rock, pop, blues, funk, metal, ambient: the GX-100's strength is chaining very contrasting sounds without changing gear. It can be direct and efficient for precise rhythm parts, yet wide and textured for delay and reverb pads or more cinematic sounds.

As soon as received as soon as tried. A product of remarkable quality, packed with technology. I owned a few multi-effects, but despite the sales arguments, the sounds sounded rather âchemicalâ, which earned me a return to basics, Vox ac30 tube amp, and carefully chosen pedals... in short, analog in good shape.
But now... this boss gx 100, what a slap!! I have not yet taken the time to modify or create my own sounds, I have only gone through the factory presets, and already you can feel a real dynamic, a warmth, a response to his playing.
The nuances are really felt like on an all-tube amp. In terms of use, without having opened the manual yet, we can easily guess how easy it is for each guitarist to shape the sound as he wants.
Finally, the connections are very complete, and to be honest, and no pun intended, it's really bad to show up on repeat with just your guitar and your GX 100... yes good OK, you also need jacks... come on... that will be the only black spot... lol...Automatically translated

Very sturdy all-metal multi-effect, very complete with the basic effects. The emulation is good, the effects are very good. Although I am not a fan of distortions in general they are exploitable. The overdrives are very good.
Only the pitch and octaver are not great and not of super good quality, like many other manufacturers in reality. Refrain from wanting to play chords with this kind of effect because it will quickly become a mess. Too bad.
The touch screen is a big plus on this multi-effect and is very practical, you can't do without it when you have tried it.
Very good mentions for the possibility of having parallel routing and being able to assign any parameters of the effects or even several at the same time to the switches. It is very flexible and it effectively replaces the snapshots that are absent from this multi-effect.
In short for the price I think I did not find better for a turnkey solution.Automatically translated

Initially, I wanted to buy the Line 6 Helix Floor. But considering the price of the beast for a product released in 2015, I quickly fell back on the much cheaper and more modern Boss GX-100 (touchscreen and Bluetooth, with the purchase of an adapter sold separately).
I am blown away by the sound quality. I have 4 amps (Fender Twin Amp, Fender Twin Amp Reissue 57, Marshall JVM410H and Vox AC15C1 for âat homeâ). It sounds good on everyone. Even on the small VOX, which does not have an effects loop, as long as you connect the pedalboard to the normal channel. Presets often require readjustments, but what could be more normal. In this regard, getting started does not take place in one evening, or even in a weekend, but once you master the machine, the possibilities seem endless. So: excellent product with a quality/price ratio that is unequalled to date.Automatically translated

A simple device to use with a little bit of habit. A very large number of sound possibilities that are very well made. For the moment I have not yet found MY sound. But I am hopeful.

Impressive. In one week I have not yet explored everything... but it's promising! In addition, regardless of the combination, there is no extraneous noise or breath.

Questions frequently asked
Can the Boss GX-100 be connected using the four-cable method?
The Send/Return loop allows integration with the four-cable method alongside a traditional amplifier. Some effects can thus be placed before the preamp, while others join the effects loop.
How many effect blocks can be used in a preset?
The routing supports up to 15 assignable blocks. Series or parallel chains can be created, especially for a dual-amp or wet/dry setup.
Is it possible to import impulse responses into the GX-100?
Importing IRs in WAV format is supported. This feature enables customization of the speaker cabinet simulation, notably to adjust bass or the high end of the spectrum.
Is the GX-100 suitable for computer recording?
The USB connection allows recording and editing on a computer via BOSS Tone Studio. A sample rate of 48 kHz is specified. Using headphones is also intended within the described applications.
What controls are available for live performance?
Assignable switches, a Manual mode, and a built-in expression pedal with toe switch provide performance control. MIDI IN/OUT ports also enable control or synchronization of other devices.
