Finally, bass guitarists everywhere are treated to the same world-class effects and amps offered by the superb BOSS GT-1B Bass Guitar Effects Processor. Designed to slip discreetly into your instrument bag or case, to be taken wherever your music takes you, delivering peerless tone control, and enviable effects that are perfect for stage and studio, the GT-1B deserves to be in every bassist's arsenal.

A world of effects at your feet

Whatever level you're at, the BOSS GT-1B is perfect for players of all abilities, ages, and experience. From beginners to seasoned pros, you'll be blown away by the sheer brilliance of this little unit. Packed with preamps for enhancing your core tone, premium effects for shaping and tweaking your output, and sublime advanced effects such as Harmonist, Synth, Defretter, everything you need is ready and waiting. Modulation, delays, reverbs, and a built-in looper too, what more could you want?!

Lightweight yet sturdy

As we've come to expect from BOSS, the GT-1B is built like a tank, yet is somehow still lightweight and compact. Slipping into the most crowded of setups is no problems at all, and if you're travelling light, then even better. Thanks to the softly rounded edges, you can rest assured that no damage will occur in transit. The seven-hour battery life powered by 4x AA size batteries makes it a perfect option for street performers, buskers or those who have a habit of forgetting their power supply (sold separately).

Intuitive control layout

Each of the three GT-1B footswitches have been carefully designed to provide intuitive functionality across patch selection, access to the tuner, looper control, and more in as compact a layout as possible. Assign the dedicated CTL1 switch to your preferred function, whether it's tap tempo, effects on/off, or a variety of others. The expression pedal and toe switch are perfect for volume, wah and a host of different effects parameters for real-time control. Those who record at home will appreciate the fact the GT-1’s USB jack will allow you to record and re-amp your tones with the DAW of your choice. Across the rear panel, a jack enables up to two additional external footswitches or expression pedals to be connected to expand the functionality of the GT-1B.
