An amp, short for amplifier, is a crucial piece of equipment that boosts the signal from your guitar or other instruments, allowing you to control volume and shape your tone. Guitar amps come in various styles, including valve (tube), solid-state, and digital modelling, each offering unique sound characteristics. Whether you’re practicing at home, recording in the studio, or playing live, the right amp can make all the difference in achieving your desired sound—from clean and crisp to rich overdrive and distortion.
Here at GPAS we have everything guitar from music to guitars amps pedals and stuff. The guitar is a versatile stringed instrument played across countless genres, from rock and blues to classical and jazz.
Typically featuring six strings, it produces sound by vibrating strings stretched over a wooden body or solid frame, amplified acoustically or electronically.
We have Guitars in all types, including acoustic, electric, bass guitars and electro-acoustic, each offering different tonal characteristics and playing styles. For many, the guitar is both a tool of expression and a lifelong obsession—lending itself equally to raw power, subtle nuance, and everything in between.
Guitar FX (effects) refer to the wide range of pedals and processors that shape and manipulate a guitar’s signal to create different sounds. From classic distortion and overdrive to reverb, delay, modulation, and pitch-shifting, effects are at the heart of a guitarist’s creative toolkit. Whether analogue or digital, stompbox or multi-effects unit, Guitar FX allow players to express mood, texture, and dynamics in unique ways. Used thoughtfully, they can transform a simple riff into something atmospheric, aggressive, or entirely otherworldly.
We have new and used Boss musical equipment available on our website for fast direct delivery from sellers across the UK & Europe.

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.
