The Boss GP-10 guitar processor gives you access to a huge amount of awesome tones and tuning in one excellent unit. Boss' unique COSM technology is built-in to deliver sublime modelling that is peerless in its execution. The sounds on offer include classic electric and acoustic guitars, basses and analogue-modelled synths - including the incredibly popular Roland GR-300. The tunings available include open tunings for slide playing, 12-string and dropped tunings.

The amazing COSM technology gives you unparalleled versatility, allowing you to summon a huge range of different sounds with the greatest of ease. There are 30 different amps at your fingertips - including combos, vintage stacks and modern high-gain output amps - so whatever style of music you play, you're bound to find something you're after.

The GP-10 contains effects that are derived from the Boss GT-100, including: overdrives, distortions, modulation effects, delays, reverb and many harmonising effects. Using the onboard expression pedal, you can create volume level effects, as well as wah and pedal bend. Whether you have a normal pickup compliment or a GK pickup, the effects can be put to excellent use.

The powerful analogue-modelled synth engine recreates an authentic emulation of the Roland GR-300 analogue guitar synth and a thick OSC Synth with two oscillators and an array of adjustable parameters. If you have a GK-compatible pickup, you can create a world of unique tones using the "Poly FX" options to blend the natural sound of your guitar with modelled sounds. There is a selection of electric guitar with different pickup combinations including humbuckers and single-coils, steel and nylon-string acoustics, basses, banjos, resonators, fretless guitar and even a sitar.

The ability to select alternative tunings in the unit itself, makes life an awful lot easier as you don't have to worry about retuning your guitar for different songs and tracks. This is particularly useful when playing live and you want a consistent action across your strings, or are limited to a single guitar.

The GP-10 has an internal USB audio/MIDI interface that makes it easy to record straight into your DAW of choice.

The Boss Tone Studio software is available as a free download, making it very easy to edit and organise the GP-10 patches on your Mac or Windows computer. By using the USB port, you can connect straight to the Boss Tone Central website to download patches that have been specially designed and created by professional players from around the world. Simply download, plug in your guitar and play!

The GP-10 is an excellent tool for any guitarist and can be put to excellent use in the studio, onstage or even just for practising. It is compact, enabling it to fit in any setup neatly. The construction is totally solid too, so you can rest assured that no matter what you throw is it, the GP-10 will always come back for more!
