A GK Rig Anyone Can Get Into!

Harnessing the power and potential of Roland's GK technology has never been easier or more affordable than it is with the BOSS GP-10. The GP-10 multi-effects processor lets you use your axe to harness a wide range of guitar, bass, and synth tones, including the classic Roland GR-300! But that's just the beginning. You can easily access alternative tunings and 12-string sounds as well, or tap into a massive collection of COSM amps and effects. Top it off with USB connectivity that lets you send both audio and MIDI to your computer, and there's no limit to what you can do with a BOSS GP-10.

BOSS GP-10 Guitar Processor at a Glance:
  • Tap into tons of cool sounds and alternate tunings with your GK-compatible axe
  • Loaded with COSM powered amps and effects you can use with any guitar
  • USB connectivity lets you expand your sonic palette and record in your favorite DAW
Tap into tons of cool sounds and alternate tunings with your GK compatible axe

When you plug your GK compatible guitar into the BOSS GP-10 multi-effects processor's 13-pin jack, you get access to a whole word of killer tones, sounds, and alternate tunings. For starters, you can switch between standard tuning, drop tunings, open tunings, and even your own custom tunings, all without reaching for your headstock. But that's just the half of it. Next up, there's the plethora of cool sounds GK opens up to you. If you're looking for electric, acoustic, or bass sounds, you'll find them all in the GP-10. But you'll also find incredibly realistic sitar, banjo, fretless guitar, and many synth sounds as well. And when you combine these with your regular guitar sound, you can end up with some truly creative and unique tones.

Loaded with COSM powered amps and effects you can use with any guitar

Okay, so not every axe in even the most high-tech guitarist's collection here at Sweetwater is equipped with a hex pickup. So, what about using your non GK compliant guitars with the BOSS GP-10? No problem. You still get to tap into the GP-10's extraordinary collection of COSM driven amp models and expansive collection of effects. We're talking about absolutely stunning overdrives and distortion tones, not to mention fun and freaky modulation effects, delays, reverb styles, and a unique intelligent harmony generator. Plus, there's an expression pedal onboard that lets you control volume swells, pitch bends, and wah effects.

USB connectivity lets you expand your sonic palette and record in your favorite DAW

BOSS gave the GP-10 USB connectivity to provide you with three very important (and cool) bonuses. First up, by connecting your GP-10 guitar processor to your computer, you get access to all of its sounds via the BOSS Tone Studio editor/librarian application. Not only does this like you go crazy, crafting all new tones in a rich graphic environment, but it lets you access innumerable user presets online. And it gets better still. You can send multi-track audio (including individual string outputs) and MIDI to your favorite software, making it easy to record with the GP-10 tones you love and to play any virtual instruments you can get your hands on.

BOSS GP-10 Guitar Processor Features:
  • An exciting and affordable way to experience the power of Roland's GK guitar technology
  • 13-pin input accommodates guitars equipped with a Roland GK-3 Divided Pickup (included) or other GK-compatible pickups
  • Get instant access to drop tunings, open tunings, custom tunings, and 12-string sounds
  • COSM instrument modeling lets you dial in a wide range of electric, acoustic, and bass guitars
  • Other modeling sounds include sitar, banjo, fretless guitar, and many others
  • Analog guitar synthesizer modeling driven by real-time DSP, which lets you play expressive, ultra-responsive synth tones
  • Create totally new sounds by blending modeled and normal guitar tones together
  • Enjoy a wide selection of high-quality COSM amps and multi-effects derived from the GT-100
  • Standard 1/4" guitar input allows for use of modeled amps and effects with any guitar
  • USB connectivity provides multi-channel audio recording (including individual string output) and guitar-to-MIDI conversion with GK pickup
  • BOSS Tone Studio editor/librarian for Mac/Windows and custom patches available at bosstonecentral.com
  • Play the GP-10 and another 13-pin GK device at the same time using the GKP-2 Parallel Cable (optional)
  • This version of the GP-10 comes with a GK-3 Divided Pickup
Discover the power of Roland's GK technology with a BOSS GP-10 guitar processor!

Tremendous options in one unit

Any cons are greatly outweighed by the pros. It doesn't excel on every front, but it does on many. I originally bought the GP10 to use as a midi controller, but I now I use all of its features variously. I just keep coming back to it because it often solves many problems. I've come to adore the oddball little box, because so many disparate features have been packed into one. You won't discover all its possibilities in a single review or description. It will take time to fully unload what it can do. Fortunately, the documentation is very thorough, although not in a single write-up. I suspect the GP-10 may eventually become a classic piece, but in the meantime it's an overlooked underdog. Get one before they're discontinued.
As with any device, keep your expectations in check. It's not a replacement for your great classic amps and pedals. It's a TOOL like any other, it solves some problems, not all of them. If you only want a bunch of standard guitar effects in one box, you may want something else, although this has some basics in that department. If you want a swiss army knife-esque palette of seemingly unrelated tools in one, this should do it.

One guitar is all you need!

The modeling and alternate tuning features allow me to pick up one guitar and do everything I need. Even without those features it's an excellent multi effects unit. Compared to other boss/roland guitar synths this is entry level only, but even so it has some really good synth sounds. All together it's a really good bang for your buck with the universe of custom tones you can create with it.

Before this I had one LP in standard tuning, one ESP in C#, one acoustic in standard, one in open D and a loaner strat in open D just so I could record some stuff in that tuning. Now I stick with my LP only and can do everything those other 4 were doing and then some.

With midi over USB I am able to play software synths from my guitar as well. You also get 6 separate audio outputs, one for each string, in addition to the standard stereo out. Which means you can use guitar-to-midi software to track each string monophonically, then the sky is the limit for synth possibilities.

If course, being able to track each string separately is an amazing feature in the studio as well. Especially when you consider this device can then be used to re-amp and even re-guitar those tracks to your heart's content.

In short, I highly recommend!

Still a tech wonder!

I use a GP-10 with a Godin XTSA guitar (with GK divided pickup/output). And though I recently moved up to the SY-1000 (which is like GP-10 on steroids)-- the GP-10 still punches way above its class. The design is excellent, and it is built like a tank-- metal chassis, metal i/o jacks.

Not only does the GP-10 do fantastic models of a wide variety of electric and acoustic instruments, it also has splendid selection of amp models and effects. The editing features are surprisingly deep, for the models, fx path, and for realtime control with switches & pedals.

The reverbs are a little weak, but they're ok.

There's a cool, little-known secret config that you can use to create an external FX send/return loop. It involves using a combination of the GK input and normal input. Be warned, it requires careful setup, as it can create a feedback loop if you don't understand how to set it up and use it. I doubt if SW wants me to paste the instructions here. :)

Amazing range of sounds

Bought this a while ago, never reviewed it, since I still use it all the time I thought I'd give my views.

I use a lot of different guitar sounds and this box just makes my life so much easier. Being able to switch from acoustic to electric and back mid-song, for example, is just awesome. If you're obsessed with just getting one perfect tone, you might prefer something else, but if you play a range of different styles, and you need to fill a lot of sonic space, this is the perfect tool.

Some detailed thoughts:
- it's worth putting effort into the hex pickup setup, especially if you want the acoustic models to sound good. I have a Godin guitar with a built-in hex pickup, needed a few tweaks to the settings, now it tracks perfectly.
- There is a TON of flexibility in things like signal routing. Programming without a laptop is do-able but fiddly. Get the Tone Studio App and you'll find things much much easier.
- the GP-10 accepts external pedals and footswitches, and has the same powerful/deep control programming features as the GT-10. With a little extra investment in a second foot control pedal and a couple of footswitches, you have a LOT of control of live performance.
- Because the tracking is instantaneous, blending synth and guitar sounds works really well. Also blending modeled guitar sounds with "real" guitar sounds.
- As with a lot of Bose/Roland products, some sounds that don't sound great in isolation work really well in a band setting. I found this to be especially true of the amp models. No idea if they sound like the amp they are supposed to be modeling, but they sound good.
- To my ears, you can get the same wonderful crystalline clean tones as you can with the GT-10.
- I don't use alt tunings much, they seem to work very well as long as you're not detuning very far from the original guitar strings.

Boss GP-10 Guitar Processor with GK-3 Pickup

Works exactly as advertised, amazing sound, endless configurations, really a pleasure to use.
For anyone who has limited space you get tons of functionality with this compact device.
I am more then satisfied with my purchase ... now for the GK-3 pickup, I dont like the design of the control module... the GK-2 was better looking and fit better on my V-cut style guitarbody, other then that it works fine.
For those on a budget its alright but if you want a cleaner look and can afford it you might want to look into the graphtech piezo ghost internal pickup.
