He was racist, red-neck piece of shit.
Go look up what he said when Obama was elected.
i was just providing information about ,
a guitar player that people likely know ,
i don't care what anyone thinks he was
MAKES YOU AN IGNORANT , RACIST, PIECE OF SHIT TOO
I'll bet he's smart enough not to try to run a
guitar amp on a light dimmer, though.

You have not lived until you put a Variac on a Kemper.
Many digital devices shit the bed if you try to take
them up slowly. Especially the ones which taste the
mains to see what flavor they are before deciding on
how they will operate. Fuck it - you probably won't
blow more than three or four fuses before you figure
out where the fun zone is. If you have a FLIR camera
you can sometimes spot temp rise from even a couple
of seconds worth of operation between power up and
the fuse blowing. Digital has its own mojo and the
digital dudes have their own tricks for finding faults.
As for me, make mine tubes - I'm too fucking old to
learn new tricks, even though I could if I wanted to.
I know a shit-ton of the ancient mojo, and that's why
I get the big money.

Semiconductors are incredibly reliable. If a device, whether
it be a lowly 1N4001 diode or the latest whiz-bang Intel CPU,
passes probe and final test it's likelyhood of failing due to
defects in materials, workmanship, or design are extremely
small. Occasional fuck-ups happen; the Seagate electromigration
debacle comes to mind. But even basic commercial grade silicon
has an astonishingly low defect and failure rate IF USED WITHIN
THE SPECIFICATIONS.
Now, board-level engineers don't generally run devices outside
of specs. They don't even usually run them close to the limits.
What they DO do is cut corners in design to save production costs.
This causes probably 98% of the failures you see in consumer gear.
Of the remaining 2%, probably around 1% are design shortcomings
due to something being overlooked, while probably 99.9% of the
remaining 1% is a board-level manufacturing defect that makes it
through testing. The remaining .001% is random defects that crop
up during operation, but even most of that is avoidable if one
is willing to spend the money. See defense, aerospace, and medical
electronics for an example that generally avoids all of the
issues because it HAS TO, and cost is no object.
Part of the "board level manufacturing defects" are self-inflicted
due to RoHS idiocy. Most common lead-free electronic solders require uncomfortably high temperatures during the reflow or wave solder
process, and the alloys lack ductility which makes them susceptible
to strain-induced failures. Due to RoHS, most leads in electronic
components are finished in straight tin plating. A large number of
random failures in consumer electronics can be traced to tin whiskers.
They are never identified because the item in question is usually
cheap, so it just gets tossed and replaced with a new one.
I could go on and on, but electronics failure analysis and prevention
is an enormous subject. There is plenty of free info online if you're interested, not to mention scores of papers written on all kinds of
failure modes, some pretty esoteric in nature.
In the case of music/audio/studio gear, most failures are caused by
what I mentioned above. "Pro" gear should be engineered and manufactured
to a higher standard, but much of it is no different design-and-build
wise from cheap consumer rubbish. Especially the shit made in China,
as we all know.

Expert, and generally arrogant prick. (Deal with it, lefturds.)
