Florestan! As far as my playing experience goes, the Stratocaster tremolo unit was a first.
Up to then, every other tremolo created tuning problems, or wasn't pitch sensitive.
I'd call that the rockabilly style, or surf style, an effect, more than a playing device.
What made Jimis' use of it different, was a first time use.
When you had a Marshall feeding back, you controlled the feedback,
by detuning, keeping it at bay, or detuning to bring it back from being uncontrollable.
That's when you kept it in your hand all the time, riding the feedback.
A good way to think of that is looking at Jimi and Ritchie Blackmore, both with Strats and Marshalls.
Ritchie was loud, but wasn't about using effects and feedback, just plugging straight into the amp.
That was big back then, Jeff Beck advertising that as another big name.
Plugging straight into the amp was about being straight, not an acid-rock musician.
When you hear Ritchie, with his Stratocaster, he uses it like a rockabilly tremolo,
moving it up and down for a big effect, not riding it for detuning or bringing up chords in pitch.
The first effect he used, a few albums in, was a Dr. Q, a kind of wah-wah simulator,
for "Stormbringer", again, not something as part of song arrangement, just a stand-alone effect for the intro.
It's easy to see Jimi in so many original ways, but it was about the use of new, inventive electronics and guitar.
For me, Mr. George Benson was a genius with his fingers, just with the strings.
Johnny was more of an acoustic guitarist right from the start, and slide player,
finding his own tone as a loud guitar player.
Now, about capos, and I've seen a lot.
It's a big jump from playing chords at the bottom of the neck, to playing a barre chord.
If a beginner guitarist is asking me for advice,
I show them how I can play chords at the bottom of the neck with my barre chord finger sticking up.
I encourage everyone to start playing with that finger in the air,
to prepare themselves for the day when they lay it down across the frets.
If there is one nice thing about using a capo, it's using one higher up the neck.
That can make your playing sound more like a ukelele, or a smaller, treble instrument,
allowing a different sound for a mix, if you have two or three guitars.
When rock videos were making it, actually when rock videos were where it was at,
I always expected to see one where a rocker was playing away on guitar,
and a sexy woman came up and put her finger up on the guitar, as a sexy move,
and acting as a barre chord finger, but I never saw that.
As far as giving someone the finger, using that upright finger as a barre chord finger,
I never saw that either.
There were a lot of statues of the middle finger giving someone the finger,
but I never saw anyone use one of those as a capo or slide.
I can see calling it a crutch, something to carry to help your playing.
Oh-oh! I must be getting to be a senior player.
I can see using a crutch as a slide, or stringing one up as a bass.
Oh, the time before synthesizers, when audiences and dancers were more a-tuned to lead guitarists.
Playing barre chords with the bass string on the bottom,
I could take my thumb and stick it out under the neck towards them and wiggle it,
and that could be a request, or when I started doing that,
people could gather up, saying he's wiggling his finger at me.
I had other guitar players come up to me, saying they heard about my wiggling finger,
and ask me to show them that.
A properly set up Stratocaster really doesn't go out of tune.
You can press the tremolo down and be playing one or two frets down,
with strings that feel very soft, letting the pitch slide up.
Leo Fender invented the Stratocaster to be a stand-up steel guitar,
and you can play it that way, if you can call that the Jimi Hendrix technique with feedback.
I could be playing with any number of other guitarists, all blending together,
but if I was riding the tremolo arm and pitch bending all the time,
that made me a unique sound that set me apart. It still works that way.
I'm surprised no violinist has ever paid someone to build one,
that would be truly singular, and I can see using your chin to control it,
or have a wire to the floor with a foot pedal.
