One technique will be banished from guitar history which is it?

Sweep picking, mostly because it usually sounds sh*t, but partly because occasionally it sounds like the sh*t and I’ve never quite mastered it.

Schnozz

Pinch harmonics and guitar faces.

Slap bass please!

Why so many people use such a fine instrument to make such a rubbish noise...

Litterick

Sitting.

Having a bit in your song where you chug on open E so you can point at the crowd with your left hand.

Derek Smalls labelled this move "projecting power".

The string rake. I can't do it, and it's overused so much, so bin it.

These are all minor infractions compared to the tragedy of the budding YouTube wannabe who starts his “shot on iPhone resting on the desk” video by waving the headstock of his guitar in front of the camera to show you an out of focus close up of the manufacturers logo emblazoned on said headstock. 

Wow, how impressed we are that you are playing an original Harley Benton.

People who thump, slap and otherwise whack their acoustics. The strings are on there for a reason, mate.

Pinch harmonics. 

Sesh

Mouthing along to the wah wah. 

Alexlotl

Tapping, no contest.

I don't mind any on the list... the trick is to not over use things. Not even VH1 has tapping on every tune. Be judicious eh?

Eric Roche may have disagreed (may God rest his soul)

Three chord blues.

I would ban tuning whilst miming, which happens all too often on TV, eg. at 48 seconds in, this video (which will start at 40 seconds in) the singer retunes a string on his guitar. Oh, how so professional looking to those that have no idea that he has no cable and is miming!

Playing with a bow. I don’t care if you are a Rock God Mr Page, you should NEVER play with a bow.

This.

Not a technique - but people not trimming their string ends.

Why? WHY??

Oh, and destroying your equipment during a gig. What a stupid thing to do.
