Swiss Army Knife for your Pedalboard

BOSS' GT-1000CORE covers all of the bases. It can be used to replace a number of stompboxes on your current board with its multitude of convincing built-in effects, but works harmoniously with external pedals too thanks to its mono or stereo inputs/outputs and dual send/return jacks - allowing for four-cable method and other modern routing possibilities.

Easily toggle between 'Memory' and 'Manual' modes to recall presets or switch effects on/off, and control deeper parameters with external footswitches and expressions pedals. You can even remotely switch channels on your amp via the GT-1000CORE! And with MIDI capability, the unit can control or be controlled by other MIDI-compatible devices in your rig.

Incredible Processing Power

The BOSS GT-1000CORE is an all-encompassing sound processing solution in a super-portable package. It allows you to travel light to any gig or recording session with zero additional pedals - or even an amp! In just a single patch, you have access to 24 simultaneous effects and can even run two virtual amps at once for a rich, textured tone.

With 250 user patches available, there’s plenty of space to store your favourite sonic creations for almost any musical scenario. The impressive DSP engine delivers on-demand power for all available effects, so you’ll never worry about running out of processing while building sounds.

A Fully-Fledged Studio Toolkit

If you love to record and play at home, the BOSS GT-1000CORE is the perfect companion. It’s a multi-channel USB audio/MIDI interface, which means that you can record with high-quality amp and effect sounds directly into your computer! It's a flexible DAW tool that can efficiently re-amp too - ideal for fastidious tone-tweakers who love to play around with their sounds in post-production.

A dedicated 'Recording' mode lets you choose from a variety of built-in speaker and microphone types, but it’s also possible to import 16 of your favorite WAV-format speaker impulse responses into the unit. In addition to this, there's an onboard looper that serves as a great function for practice, creating sounds and establishing ideas. And with the accompanying BOSS 'Tone Studio' software, you can intuitively craft sounds on a Mac or Windows computer.

Innovative AIRD Technology

GT-1000CORE harnesses BOSS’s breakthrough 'AIRD' technology - for a new level of performance, flexibility, and usability. AIRD is an evolution of the comprehensive 'Tube Logic' concept behind the Katana, Waza, and Blues Cube amplifiers, adapted to provide consistent response across the many different situations where an amp processor might be used.

AIRD enables GT-1000CORE to deliver exceptional tone and natural tube amp feel with minimal adjustments. A large selection of AIRD 'Output Select' types let you tailor the sound for any destination, whether it’s a guitar amp input, a power amp driving guitar speakers, or a full-range monitoring system - or all of them at once!

Convincing Amp & Effect Sounds

The BOSS GT-1000CORE comes equipped with a great selection of expressive guitar amplifiers, all meticulously-crafted with AIRD. There are original amp models designed by BOSS to cater for most musical styles, but also a host of famous and coveted tube amp recreations spanning from vintage favourites all the way up to contemporary high-gain fire-breathers!

BOSS are renowned for their effects though of course, so it's no surprise that GT-1000CORE comes loaded with a massive range of them. Comprised of BOSS classics, retro stompboxes, MDP effects, and advanced algorithms from the BOSS 500 Series pedals - this vast catalogue of effects will keep your creativity endlessly flowing. Multiple series and parallel routings are easy to set up with the easy-to-use interface, and with the clever 'Stompbox' feature - frequently-employed amp and effects settings can be adjusted across multiple patches in one-go.

Designed for Bass Too!

GT-1000CORE doesn't leave bassists on the sidelines; it offers exceptional sound processing and versatile DI capabilities in a portable, grab-and-go package. Three AIRD bass preamps are provided for shaping your core tone, and eight different overdrive/distortion effects are available for additional colour. There’s an MDP bass compressor too, plus chorus, flanger, touch wah, and many other effects specially-tuned for bass.

Mr David Hurst22nd Oct 2023

Still experimenting, but so far am finding this a great unit. Default patches are a bit “meh”, but loaded up Simon McBride’s patches and have been really enjoying them. The unit is capable of top-tier amp emulation, with all of the effects goodness you expect from Boss.

Only been using the GT Core for a few weeks but the sounds are very good. Took a little bit of a learning curve to get there but the pre and post EQ's really fine tune your sound. You can produce great cleans which most modellers can do, it is the overdrives that are the difficult ones, Boss do these really well in the GT Core, great drive sounds. I use mine in to my DAW and for silent practice. Thumbs up to Boss.

Like any new gear to you and certainly something with this much flexibility it has a learning curve, so just starting to get to grips with it, but love it so far. The big selling point is its flexibility but this can be its achillies heel. With so many routing options for such a compact unit, just trying to decide which one when incorporating it into your pedalboard is a real head scratcher, but hey, who doesnt love a challenge. Love it!!

Mr Neil Carrins27th Mar 2021

Fantastic sound quality and massive range of effects and amp models for the price; bought for use with guitar and bass. First time using a BOSS unit and found it relatively straightforward to use and edit patches both directly on the unit and through BTS, although it would have been nice for it to have come with a USB cable supplied (and for the USB connection to the be the newer C-type rather than micro-USB)

karl vonkalason6th Feb 2021

Very versatile with some great sounds and fantastic possibilities, For such a compact device there is a lot learn and memorise especially for old school players like myself so some patience is needed to fully maximise its potential, As with most Boss product it's very robust and super portable with a decent sized user screen however the graphics could be better as some scrutiny is needed to see what's going on but overall a great product with a lot of great sounds at your fingertips for a very decent price tag.
