Boss GT-1 

Premium Tone for Players on the Go

The GT-1 is the latest in compact multi-effects units from Boss, bringing the legendary tone of 108 different Boss effects into a grab and go, take anywhere package.  This multi-effect gives you up to 99 user preset slots in which to save your sound combinations for easy access to a whole world of tones.  The GT-1 has buttons for each effects slot in the modeler so that you can quickly see what's active on each preset, and easily turn off different effects sections (FX1/COMP, OD/DS, PREAMP, FX2/MOD, DELAY, REVERB).  A user-assignable expression pedal gives you deeper control over your sound, and the GT-1 even features a built in 32 second looper so that this should be all the pedals you need to express yourself. 

The GT-1 even connects to the Boss Tone Studio software for more in-depth fine tuning, and is compatible with Boss Tone Central so that you can download hundreds of other players' custom sounds, including those by professional musicians.  Finally, the USB jack on the back also lets you use the GT-1 as a digital audio interface to record your guitar on your computer.  The GT-1 is compatible with a standard 9V DC power supply or 4 AA batteries, so you can take it with you anywhere.  If you're looking for a small, easy to use multi-effect, try the GT-1 today!


This processor works as described and is in very good condition, showing only light external wear.  Comes with original box.
