This is the list of non dickhead guitar YouTubers:
Papa Stache
Justin
Corey
Carl
Dave Simpson
Marty
Signals
Let's Play All
Nico & Demi
Anyone not on the above list can be assumed to be a knob head.
List of confirmed knob heads:
Rick Beatoff
MIW
Dutch knobhead (Paul something)
Tim Pearse (you used to be cool, man)
I would add to the list of non-dicks;
Joey Wiedner (from West Cork)
Anyone Can Play Guitar (bit of a misnomer, not really for beginners)
Does It Doom?
Rig Rundown
That Pedal Show (up to a point)
Ben Eller (up to a point)
And to list of Knob-Heads;
The lad who looks like Russell Brand - does a lot of Anderton's videos.
Mark Zabel (also used to be cool, man)
Rick Beato is fucking insufferable. I saw one video where he talked about the fact that you even the cheapest guitar will allow you to wring a monster tone from it - "Here are some bends that you can try."
To demonstrate his point, Rick pulled out a Gibson Les Paul Custom Black Beauty - RRP about €6,000 and ran it into a rig worth about €20k
Paul Davids (the Dutch lad) is also painful. "Theesh progresshhions and schalesh are sho shimple, I wonsh evensh exschplain." and plays a fucking impossible lead line.
The Music Is Win fella is total asshole.
