However, the Gear4music extended warranty scheme provides an enhanced service, and is designed to offer a higher level of protection than many 'free' warranties offered by some retailers and manufacturers.

The highlights of this enhanced warranty service are:

  • Warranty is extended to 5 years from the date of delivery.
  • Our Money Back guarantee is extended from 30 days to 90 days (terms apply after 30 days)
  • Collection and delivery costs are included for the first two years
  • Claim 50% cash back on the cost of the policy after 5 years if it has not been used!

Please note that this extended warranty is currently only available on products sold within the EU or EEA, and is subject to the terms and conditions as detailed on the extended warranty certificate provided.

For customers in outlying areas of the country, the price of the Extended Warranty may be marginally higher, due to the potential for higher collection and redelivery transport costs.

This enhanced warranty is in addition to the standard Gear4music and manufacturer warranty policies, and the Gear4music terms and conditions of trade. No statement or condition of sale contained within these terms affects or restricts your statutory rights as defined under the Consumer Contracts Regulation 2014.

The new GP-10 puts a universe of amazing tones and tunings at your command, all in one compact processor that's affordable and easy to use. With a Roland GK-compatible pickup on your guitar, the GP-10 lets you transform your sound into numerous classic electric and acoustic guitar types, basses, and even analogue-modelled synths, including the legendary Roland GR-300. Not stopping there, you have access to instant altered tunings, including popular open tunings, 12-string tones, and down tunings that are essential for today's ultra-heavy rock styles. The versatile GP-10 also functions as a full-featured multi-effects processor for both GK and normal pickups, giving you a huge selection of COSM amps and effects for live playing and studio recording. In addition, USB connectivity lets you capture GP-10 tones directly into your DAW, and you can even play computer-based soft synths from your axe with the GP-10's guitar-to-MIDI convertor!

Incredible Versatility for Stage and Studio Playing The compact GP-10 is both an instrument modelling processor and a powerful multi-effects unit. Its multi-effects section features flagship-level COSM amps and effects, and these can be used with any guitar via a standard 1/4-inch cable. Plugging into the GP-10's GK input with a Roland GK-compatible pickup and a 13-pin cable unlocks the instrument modelling section, opening up a world of amazing sonic possibilities for both live playing and studio recording.

Instantly Change Your Guitar's Tuning

With a GK-compatible pickup, the GP-10 allows you to change your guitar's tuning with the press of a pedal. There's no need to change instruments or manually re-tune for different songs or styles-just dial up the tuning you need in the GP-10 and go. Play slide in open tunings like G and E, enjoy shimmering 12-string tones, or drop your entire guitar down in semitone steps for massive, ultra-heavy riffs. There are many tuning presets to choose from, and you can also create your own customised tunings for any application.

A World-Class Collection of Classic Guitars, Synths, and More

In addition to instant tuning changes, using a GK-compatible pickup with the GP-10 lets you change your instrument's entire sound as well. On hand are classic modelled electric guitars with single coils and humbuckers, plus steel- and nylon-string acoustics, basses, banjo, resonator, fretless guitar, and even a sitar! The GP-10 also includes an impressive analogue-modelled synth engine that powers an authentic emulation of the famous Roland GR-300 analogue guitar synth and a super-fat OSC Synth with two oscillators and many easily adjustable sound parameters. In addition, a selection of cool Poly FX deliver unique sounds only possible with GK processing, allowing you to take your playing into exciting new territory. Modelled sounds can be blended with your guitar's normal sound, putting an infinite range of tones under your fingers.

Natural, Ultra-Responsive COSM Amps

A core factor that defines an electric guitar's sound is the amplifier type, and the GP-10 is filled with them. 30 different amps are at your disposal, including classic combos, vintage stacks, and modern high-gain amps, along with bass amps for modelled bass tones and a full-range amp for acoustic sounds. Powered by custom BOSS DSP and the latest developments in COSM technology, the amps in the GP-10 deliver organic, responsive tone, with adjustable settings to vary the natural compression and playing feel. All the GP-10's amps can be used with either normal guitars or those equipped with a GK pickup.

High-Performance Multi-Effects

Inside the GP-10 is a wide selection of flagship effects derived from the GT-100. Most can be used with a normal guitar (without a GK pickup), allowing the GP-10 to do double-duty as an effects processor for any guitar gig. Included are overdrives, distortions, mod effects, delay, reverb, and more, as well as intelligent harmony and other great effects. The on-board expression pedal can be used for foot volume or effects such as wah, Pedal Bend, and others.

USB Audio/MIDI Interface Built In

The GP-10 features an on-board USB audio/MIDI interface, making it easy to record great amp and effect tones in your favourite DAW with any axe. But when you use a GK-equipped guitar, the GP-10 becomes an enormously powerful creative tool that expands your production capabilities beyond any standard guitar processor. For example, you can record the audio output of each of your guitar's strings on separate tracks, either processed with the GP-10 or captured dry for later processing. When you record unprocessed sounds in this way, you have the ability to not only re-amp the tracks through the GP-10's amps, but to 're-guitar' as well, using the GP-10's instrument modelling to change the sound to anything you want after the fact! The guitar-to-MIDI function allows you to stretch your creativity even further, using your guitar to play soft synths, capture MIDI sequences, and input MIDI data into notation software on your computer.

GK Pickup Options for the GP-10

Depending on your needs, the GP-10 is available by itself (GP-10S), or with a Roland GK-3 Divided Pickup and 13-pin cable included in the box (GP-10GK). If you already have a GK-3 on your guitar-or if you have an instrument such as the GC-1 GK-Ready Stratocaster with a GK pickup built in-you'll want to choose the GP-10S. If you want to use the GP-10's modelling functions and you don't have a GK-3, the GP-10GK is the way to go. The GK-3 is quick and easy to install on your favourite electric guitar with no modification needed.
