Boss GX-1 and GX-1B: The most affordable Boss floorboard modelers ever!
AIRD amp modeling, three footswitches, and a color display!
With the Boss GX-1 and Boss GX-1B, the pedal heavyweight presents its most compact floorboard models in the GX series so far. Like the GX-10 and GX-100, both multi-effects units feature AIRD amp modeling technology, over 140 effects, and a color display. How do the versions differ?
What is special about the Boss GX-1?
The Boss GX-1 is a highly portable multi-effects and amp modeling processor. At its core is BOSS’s renowned AIRD technology, which delivers a highly realistic amp feel and dynamics. It features 23 amp models and over 140 effects, ranging from classic overdrives and modulations to delays and reverbs.

All of this is processed with 24-bit AD/32-bit DA conversion for professional sound quality. Up to eight effect blocks can be used simultaneously, making it easy to put together complete rigs for practicing, rehearsing, recording, or performing. A color display with menu navigation buttons, three freely assignable footswitches, and an expression pedal ensure easy control.
Bluetooth audio lets you stream backing tracks directly from your smartphone. And with USB-C audio support, you can also use the Boss GX-1 as an audio interface. Plus, integration with the BOSS Tone Studio app for macOS, Windows, iOS, and Android makes it easy to edit and manage presets.
How does the GX-1 compare to the larger GX models?
The GX-1 is the compact, easily accessible entry-level model in the BOSS GX series, offering a first step into the manufacturer’s multi-effects ecosystem. While larger models such as the GX-100 offer more amp models, a touch display, and more complex routing and block options, the GX-1 packs similar performance into a more compact package.

It is aimed at guitarists who want the sonic versatility and professional sound quality of the GX series, but prefer a smaller, more stage- and travel-friendly package. The Boss GX-1 is ideal for beginners, live musicians with limited space on their pedalboard, or anyone looking for professional multi-effects performance without taking up a lot of space.
What are the differences between the Boss GX-1 and Boss GX-1B?
The Boss GX-1 and Boss GX-1B are very similar. Both are small, portable multi-effects units featuring Boss AIRD amp modeling technology, over 140 effects, a color display, and up to eight simultaneously usable blocks. Both use the new Gear Suite workflow, Bluetooth connectivity, and USB-C audio for recording and playback.

The main difference lies in the instruments and sound libraries the two products are designed for. The GX-1 is aimed at guitarists. It offers amp models and effects that match the sounds, feel, and typical dynamics of an electric guitar. The GX-1B, on the other hand, is designed for bassists. It provides amp models and low-frequency effects that keep bass tones clear and musical.
The GX-1B appeals to bassists who are looking for portable, professional tone shaping without having to adapt a guitar device to low frequencies.
How much do the Boss GX-1 and GX-1B cost?
There are several series in the world of Boss floorboard modelers and multi-effects: GT, GX, and ME, so, it’s not always easy to keep track of them all. But in terms of features and price, the Boss GX-1 and the bass version GX-1B could just be the sweet spot.
The Boss GX-1 costs $259.00 at Thomann*, and the GX-1B is available for the same price*.
