An amplifier, or amp, is a device that boosts the electrical signal from your guitar to produce sound through speakers. It plays a crucial role in shaping your tone and controlling volume. Amplifiers come in various types, including valve (tube), solid-state, and digital modelling, each offering different sound characteristics. Whether used for practice, recording, or live performance, an amp helps bring your guitar’s voice to life with clarity, power, and personality.

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.
