500W refers to an amplifier with a power output of 500 watts. This very high wattage amp is designed for large venues, professional touring, and situations where maximum volume and headroom are essential. A 500-watt amplifier can deliver powerful, clean tones even at extreme volumes and handle complex dynamic playing without distortion. It’s ideal for musicians who require robust sound reinforcement and reliability on big stages.

Bass amps are specialised amplifiers designed to reproduce the low frequencies of bass guitars with clarity and power. They deliver deep, punchy tones and are built to handle the demands of low-end sound without distortion or loss of definition. Bass amps come in various forms, including combo units and separate heads with speaker cabinets, and often feature controls tailored to bass frequencies, such as EQ settings and built-in effects. They are essential for bassists seeking to fill the sonic space in any band or recording setup.
A head is the amplifier unit of a guitar rig that contains the electronics responsible for shaping and boosting your guitar’s signal. Unlike combo amps, a head does not include built-in speakers and needs to be connected to a separate speaker cabinet. This setup offers greater flexibility, allowing players to mix and match different heads and cabinets to tailor their tone and volume. Heads come in various types, including valve (tube), solid-state, and modelling, catering to a wide range of sounds and playing styles.

Since 1973, BOSS has pioneered the development of unique and innovative products for musicians of all styles and skill levels. From class-leading effects pedals, multi-effects, and Loop Stations to guitar synthesizers, amplifiers, and more, our trailblazing designs include several world firsts and have forever changed the way people make music.
BOSS has its roots in MEG Electronics, a dedicated guitar effects R&D division founded within Roland Corporation in 1973. The company was recast with the now-famous BOSS name and logo and introduced to the public the following year. Along with products that carry the BOSS brand, the BOSS engineering team has been involved with developing key Roland-branded guitar products since the beginning.
This spirit of innovation continues today as BOSS forges ahead with the creation of original, progressive, and impactful gear. And with plenty more exciting developments on the horizon, we’re looking forward to another half-century of musical evolution.
