Nothing speaks to a guitar aficionado like the sound of a well-chosen guitar speaker. Funny though, isn’t it? Everyone, from geeky audiophiles to spotty boy racers in their earth trembling, modded wagons, knows that speaker choice has a vital part to play in the pursuit of paradisical  tone. So, why is it that we guitarists hold back when it comes to swapping out one speaker for another? That's what this guide to the best guitar speakers is here to answer.

The often-overlooked guitar speaker is significant because it’s the last link in your audio chain before your ears or, if you’re recording, your mic. Every piece of carefully curated kit that comes before it, from precision-formed string, through hand-wound pickup to point-to-point wired amp will sound compromised if they’re being fed through a duff speaker. Or the wrong speaker, for that matter.

Simon Fellows

When Simon's childhood classical guitar teacher boasted he 'enjoyed a challenge', the poor man had no idea how much he'd underestimated the scale of the task ahead. Despite Simon's lack of talent, the experience did spark a lifelong passion for music. His classical guitar was discarded for an electric, then a room full of electrics before Simon discovered the joys of keys. Against all odds, Simon somehow managed to blag a career as a fashion journalist, but he's now more suitably employed writing for Guitar World and MusicRadar. When not writing or playing, he can be found terrifying himself on his mountain bike.
