Under the hood of the GT-001’s stylish, streamlined body is a full-featured BOSS multi-effects processor with premium tone. Its COSM amps and effects are equivalent to the GT-100 with Version 2.0 software—BOSS’ top-of-the-line processor for stage performers—and patch data can be shared between the two units. Dual effects chains allow you to create sophisticated tones with two amps and series/parallel effects routings, providing pro-level performance for all your music productions. Advanced parameters include a channel divide function that lets you switch effects chains manually or according to frequency or playing dynamics, and adjustable left/right mixing for flexible audio capture in your DAW.

Via a single USB cable, the GT-001 functions as a high-quality audio interface for your Mac or Windows computer. It’s easy to capture great amp and effects tones directly into your DAW, and four audio channels provide lots of flexibility for recording, re-amping, and mixing. For example, you can listen to the GT-001’s amps and effects while capturing an unprocessed signal in your DAW, simultaneously record processed and dry tones on separate tracks, and listen to your mix while re-amping and adjusting guitar tones through the GT-001. In addition, the ability to power the GT-001 with either the included AC adapter or a computer’s USB bus offers great convenience for home setups, studio sessions, and mobile recording with a laptop PC.

The GT-001 is not just a guitar processor—you can also connect a mic to capture vocal and acoustic instrument performances into your DAW. The XLR mic input is equipped with phantom power, allowing you to use a condenser mic for top recording quality. Specially designed patches for vocals and acoustic guitars are included, providing great sound for monitoring and tracking. The GT-001 also has a stereo aux input, perfect for connecting a smart phone or drum machine for jamming when you’re not connected to your computer.

The GT-001 includes a monophonic guitar-to-MIDI function that allows you to play soft synths and other MIDI instruments in your computer from your normal axe, with no special pickup required. Powered by newly developed BOSS technology, this cool and convenient function is great fun when working with Roland’s free Guitar Friend Jam software, and also lets you experiment with using your guitar to create MIDI sequences in music production software.

Available as a free download for Mac or Windows, BOSS TONE STUDIO gives you an intuitive graphical interface for creating and editing GT-001 effects patches from your computer via USB. The software also makes it easy to organize and archive patches, and to load them as needed for different songs and styles. If your computer has Internet access, BOSS TONE STUDIO provides an integrated connection to the BOSS TONE CENTRAL website, where you can preview and download free patches created by top guitar pros directly into the GT-001. These premium patches also work with the GT-100 Version 2.0, and can be easily customized with the editing tools available in BOSS TONE STUDIO.

BOSS TONE CENTRAL is the ultimate destination for all players that use BOSS products. Evolving to include a growing selection of BOSS gear, this newly launched site gives you access to lots of premium content, including demo videos and free patches created by famous guitarists, touring pros, and session players. Check back often for new patches, how-to videos, artist interviews, and much more. If you love BOSS effects, BOSS TONE CENTRAL is the place to be!
