Taking the next evolutionary step when it comes to guitar and bass synthesis, Boss offer up the GM-800 Guitar Synthesizer unit. Combine this progressive treat with the Roland GK-5 or GK-5B Divided Pickup and gain access to the Roland ZEN-Core Sound Engine. Once fitted, your specialised synth-pickup is simply connected up via a Boss BGK cable, and besides Roland-developed sounds (including iconic Roland models like a Juno, Jupiter or Fantom), this system provides more than enough space for your own custom sounds.The Boss GM-800: Zen Core Options + Progressive Pitch-Detection Technology for Every StringAs well as a mass of Zen Core options and effects, your synth sounds can be edited in depth to create fully customised sounds. Tweak the pitch, select an alternative tuning and adjust the string and fret configuration and, to really boost inspiration, you're free to layer up to four different sounds and completely transform the output of your four-string, five-string or six-string sidekick. With the help of the onboard rhythm kit and seventy drum kit presets, you can even spit beats and your timing. All of this is backed up by the latest and best pitch-detection technology that Boss and Roland has to offer and, even if your guitar or bass is already kitted out with an older Roland pickup, with the help of a GKC-AD Guitar Synth Converter, you can plug it straight into the GM-800 pedal unit.But Wait! There's More!The library of 100 high-grade sounds that already come included with the GM-800 can be expanded even further - just dip into the Roland Cloud for some extra wave expansions and sound packs. Space for 150 scenes is provided and the 100 presets can be edited and overwritten as needed. Piling on the flexibility, this unit also supports USB audio, MIDI and MIDI I/O and comes fitted with extra ports for hooking up an expression pedal, a footswitch or external MIDI devices for even deeper hands-free control.

Part of the Boss Next-Generation Serial GK System, the GK-5 divided guitar pickup can be connected to the GM-800 guitar synthesizer and other Boss-designed guitar synths for a mass of sonic options. The special flat pickup design and included mounting materials ensure fuss-free installation in combination with most modern electric guitars - in fact, the Boss GK-5 even comes with a special bridge mounting plate to support LP-style guitars.The GK-5: Smaller and Better Than EverUnlike standard guitar pickups which send out a combined signal, the GK-5 sends out a signal for each string, giving you a host of options for tweaking the sound. The GK-5 is not only slimmer than its predecessors, it also boasts more stable signal transmission and less noise. Hook it up using a specially-designed Serial GK jack cable and be assured of optimum performance. By the way, hooking it up to the aforementioned GM-800 gives you access to the inspiring synth sounds of the Roland ZEN-Core synthesis system - just saying!

Install the Boss GK-5B Electric Bass Guitar Divided Pickup and plug it directly into a compatible synth unit via a Serial GK format TRS jack cable to completely flip and transform the sound. Besides turning your bass into a synthesizer, this setup opens up a completely new world of sound. The MIDI-pickup captures the vibration of the strings and translates it into MIDI data that, via a module like the Boss GM-800 Guitar Synthesizer pedal, can then be turned into the sound of a completely different instrument - like, any of the instruments found in the ZEN-Core Synthesis System.The Boss GK-5B: Smaller, Easier & More StableThis Boss-designed synthesizer pickup is compatible with four, five and six-string electric basses, and since this is the latest generation, is also a touch more durable than previous models. For a start, the redeveloped, more compact design is much easier to install, especially since the pickup comes including a neat mounting bracket and double-sided fastening tape. Meanwhile, the MIDI signal transfer is much more stable and the noise caused by interference has been pushed right down.

The Boss GKC-DA Guitar Synth Converter can be teamed up with various Roland and Boss GK gear to act as a digital to analogue converter when linking different socket types. This way, a guitar synth pickup fitted with the new Serial GK output can be adapted and easily be hooked up to a Boss or Roland synthesizer module fitted with a 13-pin GK port. The module also features a guitar output for directly connecting a compatible synth pedal and/or module as well as a USB port for firmware updates and, using the included power supply, you're assured of the best performance.

Specially designed for BOSS GK Series gear like the GM-800, GK-5, GK-5B, GKC-AD and GKC-DA, the BGK-15 Guitar Synth Cable is 4.5-metres-long and has been fitted with a right-angled, gold-plated stereo jack plug at either end. To counter interference and noise, BOSS have applied twisted aluminium foil and tin-plated copper shielding, while keeping things flexible by opting for a woven cable jacket. Cable binder included.

Specially designed for BOSS GK Series gear like the GM-800, GK-5, GK-5B, GKC-AD and GKC-DA, the BGK-30 Guitar Synth Cable is 9-metres-long and has been fitted with a right-angled, gold-plated stereo jack plug at either end. To counter interference and noise, BOSS have applied twisted aluminium foil and tin-plated copper shielding, while keeping things flexible by opting for a woven cable jacket. Cable binder included.

Built for brick-wall tone, the DiMarzio DP 713BK Titan 7 is relied on by Jake Bowen (Periphery) and many other modern progressive metal-heads. This ceramic neck humbucker offers a balanced mix of low, mid and high frequencies, can even support more atmospheric parts, and can technically be mounted in the bridge position as well.

The DiMarzio DP 714BK Titan 7 Bridge pickup is endorsed by Periphery guitarist, Jake Bowen - and for good reason! Where many 7-string guitar bridge pickups sound either too bright or too dark, the Titan 7 boasts proper sonic balance and keeps the seventh string from sounding muddy. At the same time, the trebles sound nicely rounded off and defined, resulting in highly recognisable tone.

The DiMarzio DP 759BK PAF7 humbucker harks back to the 1950s humbuckers and can be dropped in either the neck or the bridge position. This purpose-designed 7-string electric guitar pickup features the same technology as DiMarzio's Virtual Vintage pickups, which guarantees clear, transparent tone full of warm lows and round highs.
