Ya see, most guitars, they got three pickups wot produce the sound.
They have different characteristics.
The one wots nearest the neck has a deep sound, the one in the middle a balanced sound and the one nearest the end of the guitar is the bridge pickup and has a trebly sound.
You can choose any combination of them by using the pickup selector.
The guitar also has separate tone controls so it gives you a huge variety of sounds.
It's a fabulous bit of design.
So, our guitarist has spent so much time listening to music at high volumes he's lost the ability to hear the higher frequencies.
So to compensate for this he boosts the treble as far as it will go.
Result: horrible screeching banshee wailing.
And being a guitarist you can't tell him owt because it sets off his PMT.
Mirrors and copulation are abominable, since they both multiply the numbers of men.
