Expensive guitars often contain automatic enhancers, e.g. auto harmonics and hammond organ reverb modulators built in. It's also impossible to play a guitar under £500 fast; the frets literally won't let you, they'll cower away and shrink until a coldplay lick is played at half speed.
I bet it sounds much better too, with those active EMGs (not that the Seymour Duncans are bad at all, probably even better for jazzy sounds). What do you play on them btw? (I'm assuming it's metal) Any Metallica?
