It's hard to believe now, but before Yamaha launched its THR series just over a decade ago, the average practice amp (trust us, they were very average) sounded remarkably like an enraged wasp in a tin can. Full of custard. 

Typically thin, nasally, gutless and muddier than the Mississippi Delta, it's no wonder that players dreamed of upgrading to something like a Fender Twin, an AC30, a Mesa Boogie Mark IIC+ or a Marshall JCM800. Sadly, the well-healed ones who did would have made two alarming discoveries. First, noise abatement orders are ruinously expensive, and second, playing at neighbor-friendly volumes sucks all the tone from even the finest guitar amps.

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.
