This Roland GR-55 Guitar Synthesizer Review shows a powerful and versatile guitar synthesizer and modeling unit. It combines advanced guitar synthesis technology with an extensive collection of sounds and effects, allowing guitarists to explore a wide range of creative possibilities.
At its core, the GR-55 is designed to transform the guitar’s sound into various synthesizer sounds and other instruments. It features a divided pickup system that captures the guitar’s string vibrations and sends them to the synth engine for processing.
This allows you to play realistic and expressive synth sounds, including pianos, strings, brass, synths, and much more, directly from your guitar.
Available Features in the Roland GR-55
The GR-55 offers a wide selection of built-in sounds, with over 900 presets available. These presets include a variety of instruments, such as electric and acoustic guitars, basses, keyboards, synthesizers, and even drums. The unit also provides editing capabilities, allowing you to customize and create your own sounds using various parameters like attack, release, filter settings, and more.
One of the key features of the GR-55 is its COSM (Composite Object Sound Modeling) technology, which faithfully reproduces the characteristics and nuances of different instruments and effects. It provides realistic emulations of vintage and modern guitar amps, cabinets, and effects pedals, allowing you to achieve a wide range of tones and textures.

About Guitar Synthesizers
A guitar synthesizer is a device or system that allows guitarists to produce synthesizer-like sounds using their guitar. It combines the expressive capabilities of a guitar with the synthesis technology typically found in electronic keyboards or synthesizers. The goal is to expand the sonic palette of the guitar beyond traditional acoustic or electric guitar sounds and create a wide range of synthesized sounds, including pianos, strings, brass, synths, and more.
A guitar synthesizer typically consists of two main components: a guitar pickup system and a synthesizer engine. The pickup system captures the vibrations of the guitar strings and sends them to the synthesizer engine for processing. The synthesizer engine then generates the desired synthesized sounds based on the input from the pickups.
There are different types of guitar synthesizers available, ranging from hardware units to software plugins. Hardware guitar synthesizers often feature specialized guitar pickups, which are designed to detect the nuances of the guitar’s sound accurately. These pickups may use divided pickup technology, where each string’s vibrations are individually tracked, allowing for more precise control and articulation.
Synthesizer Engine on the Roland GR-55
The synthesizer engine in a guitar synthesizer can be based on various synthesis methods, including sample-based synthesis, virtual analog synthesis, or physical modeling. Sample-based synthesis uses recorded samples of real instruments to generate the sounds, while virtual analog synthesis emulates the characteristics of analog synthesizers. Physical modeling synthesis recreates the physics and behavior of acoustic instruments to produce realistic sound simulations.
Guitar synthesizers also often include additional features like effects processors, onboard sequencers, MIDI compatibility, and integration with software-based music production tools. These features provide more flexibility and control over the synthesized sounds and allow for seamless integration into different musical setups.
Advantages Of Synthesizers
One of the key advantages of guitar synthesizers is their ability to combine the expressiveness and familiarity of the guitar with the versatility and sonic possibilities of synthesizers. They allow guitarists to explore new sounds, create unique textures, and experiment with different genres and musical styles. Guitar synthesizers are used by guitarists in various genres, including rock, jazz, fusion, experimental, and electronic music, as well as in studio recording and live performances.
It’s important to note that learning to use a guitar synthesizer effectively may require some additional understanding of synthesis concepts and programming. However, once you grasp the basics, a guitar synthesizer can open up a world of sonic exploration and provide endless creative possibilities for guitarists.
GR-55 Multi Effects Processor
In addition to its synthesizer capabilities, the GR-55 includes a versatile multi-effects processor. It offers a comprehensive selection of effects, including distortions, modulations, delays, reverbs, and more. You can combine these effects with the synthesizer sounds or use them independently with your guitar signal.
The GR-55 also features a USB audio/MIDI interface, allowing you to connect it to your computer for recording, editing, and integrating with software-based music production tools. It supports MIDI communication, enabling you to control external devices or use the GR-55 as a MIDI controller for software synthesizers and virtual instruments.
Furthermore, the GR-55 can be used as a performance tool with its built-in phrase looper and onboard rhythm patterns. It allows you to create loops on the fly and play along with backing tracks or rhythm sections, making it suitable for live performances, songwriting, and practicing.
The GR-55 COSM (Composite Object Sound Modeling)
The GR-55 COSM (Composite Object Sound Modeling) is a technology developed by Roland that is at the core of their GR-55 Guitar Synthesizer. It is a powerful sound modeling technology that accurately reproduces the characteristics and nuances of various instruments, amplifiers, and effects pedals. COSM technology enables the GR-55 to provide a wide range of realistic and expressive sounds for guitarists.
The concept behind COSM is to analyze and model the sonic components of an instrument or effect to create a virtual representation of its sound and behavior. Instead of relying solely on samples, COSM technology uses mathematical algorithms to simulate the complex interactions and characteristics of real-world musical elements. This allows for greater flexibility, dynamic response, and control over the synthesized sounds.
With the GR-55’s COSM technology, guitarists can access a vast collection of high-quality instrument emulations. It offers a wide variety of guitar and bass models, ranging from classic vintage instruments to modern high-gain options. The GR-55 can faithfully replicate the tonal characteristics, playing dynamics, and response of different guitar types, such as Stratocasters, Les Pauls, hollow-body guitars, and more.
Modeling Cabinets
In addition to guitars, COSM technology in the GR-55 can accurately model a range of amplifiers and speaker cabinets. This allows you to choose from various amp models, including iconic classics and contemporary favorites, to shape the tone of your synthesized guitar sounds. You can even combine different amp models with the guitar models to achieve unique and customized tones.
Furthermore, the GR-55’s COSM technology provides realistic emulations of popular effects pedals. This includes distortion, overdrive, modulation, delay, reverb, and more. You can dial in your desired effects and customize parameters to create your own unique sounds or replicate the characteristics of well-known pedal configurations.
Other Emulated Instruments
COSM technology is not limited to traditional guitar sounds only. It also offers a wide range of synth sounds, pianos, strings, brass, and other instruments. The GR-55’s COSM engine allows for complex sound layering and blending, giving you the ability to create rich and textured compositions.
Overall, the GR-55 COSM technology is a significant factor in the versatility and realism of the sounds provided by the Roland GR-55 Guitar Synthesizer. It enables guitarists to explore a vast sonic landscape and access a wide range of expressive and high-quality instrument emulations, amplifiers, and effects.
Whether you’re looking for authentic guitar tones or experimenting with unique synthesized sounds, the GR-55’s COSM technology delivers a powerful and immersive playing experience.
Conclusion
Overall, the Roland GR-55 Guitar Synthesizer offers an extensive range of sounds, effects, and synthesis capabilities for guitarists looking to explore new sonic territories. It provides a versatile platform for unleashing creativity and expanding the sonic possibilities of the guitar.
